WidgetCraft
量産型おしゃれウィジェット
- WidgetCraft Getting Started: Your First Widget on the Home ScreenWhat WidgetCraft actually is, the two different things you can make in it, the four steps to a widget on your home screen, why iOS hides or delays it, and what the free tier does and does not include.
- Installing WidgetCraft: System Requirements, Permissions, Price and the First LaunchWhat WidgetCraft needs before you install it: iOS version, device, storage, which permissions it asks and when, what the free tier covers, what VIP costs, what happens on first launch, and why the App Store screen will not tell you half of this.
- Creating Your First Widget in WidgetCraft: Templates, Community, Blank CanvasThree ways to start a widget in WidgetCraft — a 200+ template, a community remix, or a blank canvas in one of six sizes — plus what the editor can change, what stays free, and why the first home screen add takes longer than it looks.
- WidgetCraft Templates: What the Library Holds, Which Are Free, and How to Use OneWidgetCraft ships 200+ preset templates across weather, calendar, photos, health rings and countdowns. Which are free, which need Premium, what the Apple Health badge on a template means, and where the limits are.
- Custom Widget Editing in WidgetCraft: Layers, Data and Real LimitsHow WidgetCraft's editor works: the layer system, every data source you can bind to, the effects and animations, and the real constraints — the 15 MB memory ceiling, iOS widget caching and the free tier's one-widget-per-size cap.
- WidgetCraft Community: Browse, Publish and Remix Widgets Made by Other PeopleHow the WidgetCraft community works: browse by category, use a widget in one tap, remix it in the editor, publish your own. What runs locally, what needs a network, and where the limits are.
ReelCraft
トランジション・アフレコ・縦動画
- How to Add Captions to a Video | ReelCraftAdd captions in ReelCraft two ways: generate them from a system-wide screen recording with speech recognition, or type them as styled text layers. Both stay editable on the timeline and ship inside the exported file.
- How to Sync Video Clips to the Beat | ReelCraftPut cuts on the beat in ReelCraft two ways: one-tap templates that are auto-timed to the music, or a frame-accurate playhead with pinch-to-zoom for placing every cut yourself.
- How to Edit a Video on Your Phone: What the Timeline Can Actually Do | ReelCraftReelCraft is a multi-track editor on the phone: split, trim, speed-ramp, reverse and keyframe under a frame-accurate playhead, import only the clips you pick, edit on-device with no account, and export up to 4K 60fps without a watermark.
- Make Reels Without a Watermark | ReelCraftReelCraft Pro exports up to 4K 60fps with no watermark straight to Photos, Share or Files. What the free tier actually adds, what Pro costs, and how to check before you export.
WaveCraft
DTM・多重録音スタジオ
- How to Remove Vocals from a Song | WaveCraftRemove the vocal from any track on your iPhone in one pass. What separation actually does to the mix, which sources separate cleanly, what no tool can fix, and what the two outputs really give you.
- Vocal Separation vs Stem Separation: What Each One Is For | WaveCraftVocal separation gives you two files; stem separation gives you four. What each one is actually good for, why four-way separation can sound worse than two-way, and how to tell which one your track needs.
- How to Denoise a Recording on iPhone: What the Tool Actually Measures | WaveCraftNoise reduction estimates the steady noise in your take and subtracts it, frequency by frequency. What it measures before it runs, what the strength slider does, what it cannot fix, and the order that works.
- How to Make a Karaoke Track: Vocal Removal, Bleed, and Rights | WaveCraftMake a karaoke track on your iPhone with WaveCraft: separate the vocal, keep the instrumental, clean the bleed, and understand the copyright line between private practice and public upload.
- Can I Record a Full Song on My Phone? | WaveCraftYes — a full song can be recorded and finished on a phone. The whole WaveCraft session from first take to lossless export, which stages are free, and exactly where a phone session stops.
- Audio Mastering on Your Phone: What the Chain Actually Does | WaveCraftWhat mastering on a phone actually is: the compressor, the limiter and the loudness target behind WaveCraft's three presets, the real LUFS and ceiling numbers, and the four things mastering cannot fix.
AllergyLens
乳糖・食物過敏を判定
- Scan Food for Allergens Before You Eat: How Camera Scanning WorksCamera allergen scanners see whole ingredients well and trace amounts badly. What AllergyLens detects, what it misses, how its four-level verdict differs from reading a label, and how to use it on a restaurant menu.
- Keep a Separate Allergen Profile for Everyone at Home | AllergyLensA shared allergen list is wrong for a household with one anaphylactic sibling and one shellfish intolerance. How AllergyLens models per-person profiles, per-allergen severity and per-profile emergency details, and what stays on device.
- Where Is My EpiPen When I Need It? | AllergyLensAllergyLens keeps a permanent one-tap SOS on severe-grade profiles: your EpiPen location, emergency contact, hospital and the emergency number. Here is exactly what that screen is worth, what it is not, and the minute of setup it depends on.
CosmeticLens
敏感肌の成分解析
- Reading a Skincare Label With No Barcode and No Product Database | CosmeticLensBarcode scanners can only read what is already in a product database. CosmeticLens reads the printed INCI list itself with on-device vision plus a backend model — what that changes, how it fails, and what it costs.
- Your Own Sensitivity Profile: Skin Type, Life Stage and 12 Avoidance Categories | CosmeticLensCosmeticLens matches every scan against a profile you build and edit yourself — skin type, life stage and 12 avoidance categories — and never puts the profile behind a paywall. What it changes, what it cannot know, and where the free tier actually ends.
- Will an Ingredient Scanner Ever Say a Product Is Safe? | CosmeticLensMost ingredient scanners quietly imply a verdict. CosmeticLens does not: it labels each risk as coming from a published source or AI inference, shows the failure modes, and leaves the call to you.
Cozy
気分記録・癒しの育成ペット日記・メンタルケア
- What a Five-Second Mood Check-In Actually Includes | CozyA five-second check-in is a mood, the factors that mattered, and an optional note. Here is what those five seconds do and do not capture, what changes with Premium, and how to tell whether the habit is working.
- Mood Tracker App for iPhone: What Actually Makes One StickMost mood tracker apps are abandoned within three days — not because the app is bad, but because the daily act costs more than it returns. What fixes that, what Cozy does differently, and what to look for before you install anything.
- Read HRV Stress Insights from Apple Health | CozyCozy reads SDNN heart rate variability from Apple Health read-only, classifies stress against your own 30-day baseline on-device, and pairs weekly and monthly trends with your moods. Here is the exact math, what it needs, and where it stops.
- Cozy's Home Screen Widget: What It Actually Does, Size by SizeCozy ships a free Home Screen widget for logging a mood: small opens the add page, medium and large put five mood levels one tap away. Sizes, setup, limits, and what it costs.
ProofLens
法廷レベルの電子証拠
- Prove a Photo Wasn't Edited: How Tamper-Evidence Works | ProoflensA SHA-256 hash proves a file has not changed since it was hashed, an RFC 3161 timestamp proves when, and a Bitcoin anchor stops the timestamp being rewritten. What each layer does — and does not — establish.
- Burn GPS, Time and Notes into a Photo | ProoflensHow Prooflens bakes date, time, GPS, altitude and a free-text note into the pixels at capture: the exact order of operations, the UTC timestamp, the five templates, the free-versus-Pro line, and where a burned watermark stops and the cryptographic proof begins.
- Court-Admissible Photo Evidence: What Prooflens Actually ExportsA photo is only evidence if the person receiving it can check it. What Prooflens puts in the exported .zip and PDF legal statement, how a third party verifies it without the app, and what admissibility still depends on.
Sleeve
FLAC対応 オフライン音楽プレイヤー
- Does Sleeve Copy or Import Your Music? No — It Reads In PlaceSleeve has no import step. It reads FLAC, ALAC, MP3 and the rest where they already sit — a folder, iCloud, Dropbox or a WebDAV NAS — so nothing is duplicated, storage cost is zero, and renames at the source propagate.
- Stream Lossless from a NAS: WebDAV, the Cache, and When the NAS Sleeps | SleeveHow Sleeve streams FLAC, ALAC and the rest from a NAS over WebDAV without copying anything, what the local cache covers when the Wi-Fi drops, what it costs, and how it compares to SMB or AirPlay.
- Music Player With No Ads and No Account | SleeveSleeve embeds no third-party ad or tracking SDKs and has no sign-up, so there is no user table. What it does send, what stays on your device, and where the free tier ends.
SnapSweep
重複写真をまとめてスッキリ削除
- Bulk Delete Screenshots on iPhone: How SnapSweep Makes It SafeBulk-deleting screenshots only works when the app knows what each one is. SnapSweep classifies them into 11 categories on device, applies a per-category expiry rule, and lets you swipe left to delete, right to keep.
- Save the Info in a Screenshot Before Deleting It | SnapSweepSnapSweep's Info Vault pulls phone numbers, URLs, addresses, tracking numbers and verification codes out of a screenshot before you delete it, scores every candidate, and gives each one a button that does what it says.
- Find Duplicate Photos: What Near-Duplicate Detection Actually Does | SnapSweepSnapSweep groups near-duplicate photos with a two-stage matcher, proposes the best shot by a quality score you can override in one tap, and suggests video compression only when the estimate says it is genuinely worth the re-encode.
HourStamp
勤務時間と残業代記録
- Public Holidays and Make-Up Workdays: How HourStamp Counts the DayStatutory holiday calendars for 44 regions across 2024–2027, including mainland China's official schedule and Taiwan's labour holidays with their make-up workdays. Multipliers can be tiered by hour where the law says so, and every amount is an estimate, not a wage determination.
- How Is a Pay Estimate Calculated? | HourStampHourly basis, cycle dates and the day-type multiplier stay visible on every estimate, and the 21.75-day versus 166.64-hour dispute is spelled out so you can choose. HourStamp also checks a payslip on device.
- How to Keep a Personal Record of Hours Worked | HourStampA record only helps if it survives being questioned. HourStamp stamps device time, pay settings and the day calculation, keeps explicit edits as revisions, stores the ledger on device with no account, and exports a PDF summary.
Tinta
写真の配色パレットとカラーコード
- Get a Colour Palette from a Photo | TintaHow Tinta reads six colours out of a photo, why the biggest flat area often is not the colour you wanted, what the palette really contains, and when it goes wrong.
- Get Exact Hex Colour Codes from a Photo | TintaEvery colour Tinta pulls from a photo carries an exact HEX value. How the number is derived, what it does and does not tell you, and where the obvious alternatives fall short.
- Build a Colour Scheme from a Photo | TintaA palette is what the photo contains; a scheme is what you can build with. How Tinta's subject-aware palette, harmony suggestions and twelve mounts turn one picture into a usable, exact set of colours.
- Save a Colour Card as an Image: Export Sizes, P3 and the Free-Tier WatermarkWhat Tinta actually exports: JPEG 2K free, JPEG 4K and lossless PNG up to 6144px with Pro, P3 wide-gamut with an ICC profile on every tier, six aspect ratios, and which mounts carry a free-tier watermark.
Wick
ディープワークで勉強に没頭・先延ばし断ち
- Does Wick Actually Block Apps? What the Shield Really DoesWick's Shield uses Apple's Family Controls framework to genuinely block the apps you pick during a focus session — three friction levels, always lifts when the candle goes out. Here is what it blocks, what it does not, and where it falls short.
- Flowtime vs Pomodoro: Which Rhythm Should You Use?Flowtime counts up until you decide to stop; Pomodoro counts down from a fixed 25. Wick ships Pomodoro, Flow and a plain timer, with an almanac that records both honestly — here is what each rhythm actually does.
- Is Wick a One-Time Purchase or a Subscription? | WickWick's focus ritual is free in full and Wick Pro is a single one-time purchase with no subscription, no trial to expire and nothing to cancel. What the free tier covers, what Pro adds, and how the restore works.
YoloShell
SSHターミナル・踏み台・VNC
- Keep an SSH Session Alive When the Wi-Fi Drops | YoloShellWhy SSH dies when your phone changes network, what Mosh roaming actually changes, where roaming stops working — UDP blocks, a missing mosh-server, iOS backgrounding — and what roaming costs in YoloShell Pro terms.
- Run a Coding Agent on Your Server from Your Phone | YoloShellYoloShell's Herdr panel lists every workspace, tab, pane and agent on a remote machine, starts an agent in a shell pane, shows its real status, and lets you observe read-only or take control explicitly.
- Use tmux Panes and Tabs on an iPad | YoloShelltmux on iPad is usually a text screen. YoloShell runs tmux in control mode (-CC) for a native tab and pane UI, adds Chrome-style tabs, live titles from OSC sequences, a prefix key bar, and the honest limits.
Piko
写真で学ぶ中国語
- Learning Chinese by Photographing Things: What a Snap Actually ReturnsWhat a snap returns in Piko, what happens when the object is not in the 159-word table, the four ways recognition fails and the exact wording it uses, where the photos go, and how photographing compares with a flashcard deck.
- Stroke Order and Pinyin Tones: How Piko Teaches Both TogetherStroke order and tone are two different systems, learned by eye, hand and ear. Here is how Piko teaches both on one free character card — meaning, spoken pinyin with tones, stroke-order animation, and character origin — and where it stops.
- How Piko Reviews Saved Characters: Spaced Repetition, Grade by GradePiko brings saved characters back on a real schedule — 1 day, 6 days, then a growing interval — and tracks 730 grade-1 and grade-2 characters. What the review loop does, what it cannot do, and what Pro costs.
Encore
一年前の今日、忘れてた写真
- Photos Your Camera Roll Has Been Hiding: How Encore Finds Them | EncoreThe good run of photos is usually still on your iPhone, buried in a flat pile. Encore reads the whole library on device, ranks by rarity rather than recency, and shows the reason for every pick.
- Video of the People Who Keep Appearing in Your Photos | EncoreHow Encore decides someone keeps appearing, what it stores on your iPhone, how long it keeps it, and exactly what turning it on does and does not do — including the part that is still being built.
- Keep a Moment as a Film or a Live Photo: What Encore Actually Saves | EncoreEncore Pro saves a whole piece as a 1080x1920 film, or the frame you are watching as a 1.5-second Live Photo. What each one really contains, what fails, and where the app stops.
InkBoard
Notes, sketches, and whiteboards on one flexible canvas
- Notes and Whiteboards in One Document: How InkBoard Combines ThemWhy one page can hold a heading, a sketch, a screenshot and a PDF without any of them turning into a picture: InkBoard keeps every stroke as an editable, searchable object. Free tier, local-only, iOS 17+.
- Where InkBoard Notes Actually Live: On Your Device, and the App Says So | InkBoardInkBoard keeps each note as a file package in your device's app container, requires no account, and shows a disabled iCloud row reading "Sync isn't available yet" instead of a sync button that does nothing.
- Export a Whole InkBoard Document as PDF: What the Pro Line Costs | InkBoardInkBoard exports one page to PDF, PNG or JPEG free. Exporting a whole document as one multi-page PDF, and printing from the app, are Pro. Here is what the exported file contains, where it fails, and what Pro costs.
JobProof
Contractor Reports
- Required Job Photos Before Leaving Site | JobProofJobProof's default plan asks for 8 required shots across Before, During and After, and refuses to build a report until every one is filled. Here is what the 8 are, how the leaving-site check works, and where it stops.
- Detect Later Edits to a Job Photo | JobProofJobProof keeps the captured original immutable and computes local SHA-256 hashes of the image and canonical manifest, so a later change is detectable. What that establishes, what it does not, and what to know about the limit.
- Customer Sign-Off Tied to a Report Version: What It Proves | JobProofJobProof binds the customer's name, acknowledgement and optional signature to one exact report version, and refuses a duplicate or stale sign-off. What that proves, what it does not, and how it compares to a paper form.
Linea
One continuous family timeline, from planning to age three
- One Timeline from Planning to Age Three: What Actually Carries Over | LineaWhat really crosses the seam at birth: a five-tab spine that never moves, a stage computed from dates instead of stored, parent and baby as two subjects, and the three things one timeline deliberately does not merge.
- Stage-Aware Tasks and Reminders That Re-Derive Themselves | LineaHow Linea derives its task list from your gestational week or your baby's month age, why regional schedules differ, and exactly when a reminder fires.
- Family Records Not Designed to Be Sold | LineaWhat on-device-first actually means, what deletion really removes, and where the promise stops: the honest limits of keeping pregnancy records on your phone and nowhere else.
MenuLens
海外メニューをカメラ翻訳
- Getting Started with MenuLens: Your First Menu, Step by StepHow MenuLens works from install to your first translated menu: Apple sign-in, the five permissions, the 10 free scans, and exactly what a Premium subscription adds.
- How MenuLens Translates a Menu: Target Language, Region, and PreferencesA menu translation is only as good as its context. How target language, region, and your stated preferences change what MenuLens produces, and the limits to know before you rely on it.
- Dish Details in a Menu App: What MenuLens Shows and What It GuessesEvery dish page shows a name, an ingredient guess and a flavor note. Here is what MenuLens puts on that page, where the AI inference stops being reliable, and how a pick becomes an order sheet.
- MenuLens FAQ: Free Scans, Photos, Billing, and What AI Must Not DecideWhat happens to the menu photo you take, the free scans you get before Premium, how billing and refunds work, and the one question AI output must never be trusted to answer.
Loopal
Chinese typing that always knows what to say
- Ask a Question From Inside Any App | LoopalLoopal is a Chinese keyboard with a conversational assistant inside it: hold the space bar to open a conversation, and the answer lands in the field you were typing in. Here is exactly what it sends, what fails, and when it is the wrong tool.
- Bring Your Own AI Backend: Anthropic, OpenAI, Doubao, Gemini or Ollama | LoopalLoopal runs on platform credits out of the box, on your own Anthropic, OpenAI, Doubao or Gemini key, or on an Ollama server on your LAN — what each path costs, where the request goes, and which models it accepts.
- 9-Key, Handwriting and Full Pinyin in One Chinese Keyboard | LoopalLoopal ships three Chinese input layouts — continuous Pinyin, a 9-key grid for one hand, and handwriting for rare characters — behind one keyboard extension, with candidates and recognition running entirely on device.
Rifff
A feed of living content you can remix
- Living Content: What It Means When Each Feed Item Actually Runs | RifffLiving content means each item in Rifff's vertical feed is a program that runs on your phone, not a file that plays on it — what runs, what fails visibly, what it costs, and where the line is.
- How to Remix and Continue Someone Else's Post in RifffYes — tap riff on any item in Rifff to remix or continue it. What a remix actually copies, how the riff lineage tree works, and the one-at-a-time session limit.
- Create and Edit a Post Just by Talking | RifffRifff transcribes your voice in real time so you create and edit content by speaking, not typing. How hold-to-talk works, what happens on permission denial or an empty recording, what your words actually trigger, and the limits.
Selene
月相・月齢カレンダー・旧暦
- Is the Moon Worth Looking Up Tonight? A One-Line Verdict | SeleneSelene answers is tonight worth looking up with one line, not a percentage. Five fixed rules arbitrate cloud cover, moon altitude, your local horizon and rare events; when there is no weather source it says so instead of guessing.
- See the Moon on Any Date: Two Weeks Free, Any Date With Pro | SeleneSelene's date scrubber moves the moon through its real arc and sky for two weeks either side of today, free. The full calendar of rise/set, phases and folk moon names never sits behind a paywall.
- Find the Moon in the Sky: How Pointing at It Actually WorksFinding the moon is a pointing problem, not a compass problem. How the free AR overlay in Selene uses your camera's real field of view and the device's attitude to tell you which way to turn — and what it does when the moon has not risen yet.
