Private fitness tracking · iPhone

Notch by notch.

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.

Coming soon to the App Store Free during launch · No subscription
What it does

Three things, done quietly.

No nutrition tracking, no AI coach, no social feed, no leaderboard. Just the things that actually move the needle.

Weight, every day

One tap to log. A clean trend chart. 7-day, 30-day, 90-day, and lifetime views. kg or lb, your call.

Activities, all of them

Cardio, strength, mobility, sport. Forms tuned to each — sets and reps for lifts, distance and pace for runs, intensity for yoga.

Photos, redacted forever

Black out faces, tattoos, anything you want — permanently baked into the saved file. The original never touches storage.

A different approach

Your data, on your device.
That's the whole pitch.

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.

No accounts Open the app and start tracking. There's no signup because there's no us to sign up to.
Encrypted at rest SQLCipher protects your database with a per-install key kept in the iOS Keychain. Photos sit in the app's protected sandbox under iOS Data Protection. Optional Face ID lock on top, if you want extra friction.
No analytics, no trackers No analytics SDKs, no crash reporters that phone home, no third-party data-collection code. Nothing you didn't ask for.
Redactions are permanent Black out anything in a progress photo and the original is destroyed before save. EXIF stripped too.
Export anytime One tap exports your full data as JSON. Photos stay on your device — copy them out via Files or AirDrop when you want to.

FAQ

Reasonable questions.

What happens if I lose my phone?

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.

Will my data sync to my iPad or another iPhone?

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.

Does Notch work with Apple Health?

Not yet. After launch we'll add an optional, two-way HealthKit integration: pull weight and workouts in from Health, push your Notch entries back so they count toward your Activity Rings or show up in other apps you use. Both directions are off by default — you turn on what you want.

What about Android?

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.

Why free? Will it always be free?

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.
