Phi Focus: Study Timer

Phi Focus is a study timer and focus tracker that works offline. No sign-up, no ads, no analytics. Time your study with a stopwatch or pomodoro, see where your hours go, and keep a daily streak.

Your subjects, sessions, to-dos and notes stay on your phone. They are never uploaded.


FOUR WAYS TO LOG TIME

• Stopwatch: start, pause, stop. Simple as that.
• Pomodoro: your own focus and break lengths, with sound and vibration alerts.
• Phone-down mode (Pro): put your phone face down and the timer runs. Pick it up and it pauses. Only real focus time counts.
• Manual entry: forgot to start the timer? Log the session afterwards.

The timer keeps running in the background and survives restarts. Go full screen with your own wallpaper and your to-dos beside the clock.


SUBJECTS, TARGETS & PLANNING

• Subjects for whatever you study: Physics, Maths, DSA, anything
• A daily target that fills up through the day, with a small celebration when you hit it
• An optional streak with your own minimum, so a 5-minute day doesn't count
• To-do list linked to your subjects
• Weekly schedule with reminders, so you know what to study next


INSIGHTS THAT MEAN SOMETHING

• Today's total and per-subject breakdown
• Weekly, monthly and yearly charts with week-over-week change
• Your best day and your strongest weekdays
• Subject share chart
• Year heatmap: your consistency at a glance
• Full session history, filtered by subject and date
• Share cards for your day, week or month, made for stories


STUDY WITH FRIENDS (OPTIONAL)

• Make a room and send one link. Friends tap it and join.
• See who has studied the most today
• You get a random name like "Quiet Falcon 27": no email, no phone number, no password
• Only your total minutes for today are shared, and only with people in your rooms
• Off until you turn it on. Turn it off and your data is deleted from the server.


BACKUP & RESTORE

Save everything to one file and bring it back on any phone. Restoring is always free.


FREE, WITH OPTIONAL PRO

Phi Focus is free, with no ads and no limits on subjects or sessions.
