Phi Focus

A simple, offline study-time tracker. No sign-up, no cloud sync, no ads.

Four ways to log time

Stopwatch: start, pause, stop.
Pomodoro: your own focus and break lengths.
Phone-down mode (Pro): put your phone down and the timer runs. Pick it up and it pauses.
Manual entry: forgot to start the timer? Log it afterwards.

Subjects, targets and insights

Make subjects for what you study, set a daily target and watch it fill up. Weekly, monthly and yearly charts, a year heatmap, and a full session timeline show how you are really doing.

Your data stays on your phone

Subjects, sessions, to-dos and schedule never leave your device. There is no account to make.

Study with friends (optional)

Make a room, share its code, and see who has studied the most today. You get a random name, and only today's total minutes are shared, only with people in your rooms. It is off until you turn it on.
