Beta access

Try Return before the public launch.

TestFlight installs the beta. Telegram is where build notes, testing coordination, and feedback live.

What Return does

A quieter way to understand your days.

01

It reads what your Watch already knows.

Sleep, HRV, mindfulness, activity — Return uses the data your Apple Watch is already collecting. No extra logging, no extra wearables, no new habits to build.

02

Two questions. Not a questionnaire.

Rate your willingness and control in ten seconds. That's enough for a transparent model, grounded in forty years of self-determination research, to find the pattern.

03

See why, not just what.

Return doesn't just show a score. It surfaces the three factors — out of fifteen health signals and daily contexts — that moved your autonomy up or down.

Your Apple Watch already knows your body.
Return tells you what it means — tracking how free your days feel, not just how active they were.

Inside Return

More than two questions.

On your wrist

An Apple Watch app, not just a companion.

Record a check-in from your wrist with the Digital Crown — three steps, under ten seconds, no phone needed. Your autonomy estimate, today's timeline, and a seven-day trend live in complications for any watch face.

On your home screen

Widgets, Dynamic Island, and Siri.

Glanceable score on Home Screen widgets (small and medium), on the Lock Screen, and in Dynamic Island. "Hey Siri, record autonomy" works hands-free. Tap a widget to log or check your trend without opening the app.

Look ahead

A What-If simulator, grounded in your own model.

Move nine sliders — sleep, HRV, exercise, mindfulness, noise, mood — and see how tomorrow's autonomy might shift. Presets for an Ideal Day or a Recovery Day. The predictions come from your data, not averages.

Always private

On-device, end-to-end.

AES-256-GCM encryption with a device-only Keychain key. Records stay local by default, and iCloud sync is optional. No telemetry, no Firebase, no cloud analysis.

Data boundaries

Private by design, not by promise.

Local first

Every record, mood, note, and health metric is encrypted and stored on this device by default. With iCloud sync off, your data never leaves the device.

Apple Health

Sleep, HRV, and activity require explicit Apple Health permission. Optional mood write-back to State of Mind exists, but both directions are off by default.

iCloud sync

When enabled, your records and personal model weights sync through Apple iCloud across your devices. Apple Health-origin data is excluded from iCloud sync.

On-device AI

Apple Foundation Models run on-device on supported iOS and macOS releases. Off-device cloud AI is never used unless you explicitly turn on a separate toggle.

Built on forty years of research.

The model behind Return draws on forty-plus peer-reviewed papers across self-determination theory, sleep science, HRV, and psychophysiology. See the sources.
