A quiet fitness tracker for weight, workouts, and progress photos. Everything stays encrypted on your phone — no accounts, no servers, no analytics, no one looking over your shoulder.
No nutrition tracking, no AI coach, no social feed, no leaderboard. Just the things that actually move the needle.
One tap to log. A clean trend chart. 7-day, 30-day, 90-day, and lifetime views. kg or lb, your call.
Cardio, strength, mobility, sport. Forms tuned to each — sets and reps for lifts, distance and pace for runs, intensity for yoga.
Black out faces, tattoos, anything you want — permanently baked into the saved file. The original never touches storage.
Optional two-way sync. Weights and workouts can flow in either direction, automatically — and the privacy story holds because Apple Health data stays on this device too.
The privacy story isn't buried in a settings page — it's part of the app's chrome. A small lock badge sits in the header on every tab. Tap it any time to see exactly how Notch handles your data, in plain language and in technical detail.
A welcome screen saying "we keep your data private" is just a claim. A small lock badge that you can tap to see the actual security parameters — file paths, encryption details, exactly what's stored — is a receipt.
Privacy chips on every entry surface mean you're reminded of the rule at the moment you're being asked to commit data, not buried three menus deep.
For the curious, every claim on this page is verifiable in-app and in the privacy policy.
Most fitness apps are hungry for your data. Notch is the opposite: nothing leaves your phone, because there's nowhere for it to go. No cloud, no account, no servers, no exceptions. Six rules, the same ones the app shows you on the inside.
Notch is free while it finds its footing. A small one-time price will land later — and if you grab it during the free window, that copy is yours forever. No subscription, ever.
Tap the lock badge in the top-right of any tab. A bottom sheet slides up with six plain-language bullets covering storage, photos, accounts, analytics, biometric lock, and exports. A "Technical details" expander reveals the cipher, the key location, and the framework names. For the full inventory — Face ID toggle, auto-lock timeout, what's actually stored on your device, the database file path — go to Settings → Security.
Your data is on the phone, encrypted. If the phone is gone, the data is gone. Use the JSON export regularly and stash the file somewhere safe — iCloud Drive, a USB stick, your call. Notch never makes the choice for you.
Not in v1. Sync is hard to do without compromising the privacy story, and we'd rather not ship it than ship it badly. If we add it, it'll be opt-in and end-to-end encrypted with a key only you control.
Yes — optional, two-way sync for weights and workouts. Four independent toggles in Settings → Apple Health (read activities, read weights, write activities, write weights). All four start off; you flip what you want. Imported items show a small "From Health" badge so provenance is always visible. Photos and habits never sync — HealthKit has no place for them, and progress photos stay strictly inside Notch. See the Apple Health section above for the full picture.
iPhone first, and probably iPhone for a while. The codebase keeps Android possible, but the privacy guarantees are tighter to deliver on iOS, so that's where we're starting.
SQLCipher (AES-256) via op-sqlite. The encryption key is generated per install and stored in the iOS Keychain. Photo files live in the app sandbox under NSFileProtectionComplete — Apple's strictest data-protection class. Biometric lock uses iOS LocalAuthentication.framework.
Free at launch while the app earns trust and gets feedback. Once it's stable, the plan is a small one-time price — never a subscription. If you download during the free window, that copy stays free forever; the price change applies to new downloads only.
One person, in their spare time, because they wanted it to exist. Email echo.2dma8a@bumpmail.io to get in touch.
