FIND YOUR RHYTHM Explore 7, 30, and 90-day views with daily totals, activity balance, a twelve-week consistency map, outcome distribution, and Rhythm Lens, which highlights the time of day when focused work tends to go best. BUILT FOR PRIVATE PROGRESS - Works offline with no account - Stores app data on your device - Exports JSON backups and CSV session history - Offers optional Calendar export and timer notifications - Switches instantly between English and Simplified Chinese - Supports light and dark appearance Hourproof - Ledger helps you make your hours accountable, one honest receipt at a time.
