What is inside
The essentials for recording real hours.
Proof is intentionally small: a private record, useful stats, and share cards without accounts or feeds.
Work and sleep sessions
Track active blocks with simple start and stop actions, then review each session later.
Weekly insights
Understand totals, averages, streaks, trends, and the relationship between work and rest.
Local share cards
Turn selected stats into story or square PNG cards generated directly on your device.
Private by design
Your history stays local. Purchases are handled through the App Store or Google Play.
Daily flow
Record the block, then let the archive build itself.
Proof is designed for repeated, low-friction use rather than setup-heavy time tracking.
01
Start a work block
Tap once when focused work begins and keep the timer running in the background.
02
Record sleep
Start sleep at night, stop when you wake up, and assign the rest to the right day.
03
Review the pattern
Use history and insights to see what actually happened across the week.
Privacy
A personal record should not need an account.
Proof does not use a custom server, ads, or analytics. Export and import are local backup tools, and deleting the app may delete local history unless you back it up first.
