About this app

Tessera is a personal time tracker for people who already think in quarters of an hour.

You split the day into named sections — two hours, or whatever you actually live. Every 15 minutes becomes one tile. Tap what filled it. Add a note if you want. Done.

Four ways a quarter can go
• Work
• Skill
• Soul & Body
• Wasted

A quiet reminder at the end of each quarter asks what just happened. Answer from the notification in one tap, or open the day mosaic and write a line.

See the week and the month as a mosaic, not a spreadsheet. Hours land in the four categories so you can see where focus actually went.

Built to stay on the phone
• No account
• No Tessera server for your logs
• English and Persian
• Dark or light
• Backup and restore as JSON
• Export to Excel or CSV when you want a file you control

Reset clears logs if you need a clean slate. Sections, language, and theme stay.

Tessera keeps the ritual: fifteen minutes, one tile.
