Focus Timer - Pomodoro Study

Focus Timer is a Pomodoro timer built around one habit: 25 minutes of focus, then a 5-minute break. Open it, press start, and the ring begins to close — no account, no setup, no tour.
The circular ring shows how much of the session is left, with the exact minutes and seconds inside it and today's completed focus sessions just below.
Everything runs offline on your phone. There is nothing to sign in to and nothing to upload.

Focus apps tend to grow: projects, tags, trees to plant, leaderboards, subscriptions. This one has a timer, a week of statistics and a notification when the session ends.

One tap to start
• Press start and the focus phase begins immediately, 25 minutes by default
• Pause when you are interrupted and resume exactly where you stopped
• Skip moves to the next phase; stop clears the session and returns to the start
• A large ring and an mm:ss readout you can read from across a desk

Your own lengths, if 25/5 does not fit
• Focus: 15 to 60 minutes, in 5-minute steps
• Break: 3 to 15 minutes, in 1-minute steps
• New lengths apply from the next session, so a running timer never jumps
• 50/10 for deep work, 15/5 for flashcards — set it once and leave it

Step away; the session still ends on time
• The remaining time is recalculated from the moment the session is due to end, so switching apps or locking the screen never throws the count off
• At that moment a local notification tells you the session is over — you do not have to keep the app open and watch the ring
• A session that finished while you were away is recorded as soon as you return, stamped with the time it actually ended
• When a phase ends the app moves on but waits for you to press start, so a break you never took is never logged as one
• Notifications are scheduled without the exact-alarm permission, so in Doze or battery saver they can arrive a little late; your session records are not affected

Seven days at a glance
• Completed focus sessions for today, this week and all time
• Total focus time accumulated so far
• A bar chart of the last seven days, so a broken streak is obvious
• Only completed focus sessions are stored; breaks are not recorded
• Clear the whole history from Settings for a clean slate

Why the app asks for notifications
Focus Timer asks for one Android permission you will actually see: notifications, once on first launch and again when you switch notifications on in Settings. Decline it and the timer still works — you simply check the screen yourself. A second declared permission restores scheduled notifications after a reboot; it is not sensitive and is used for nothing else. There is no location, camera, microphone, contacts or storage access. Sessions stay in a database on the device and are never uploaded, so there is no account to create, and only the ad SDK uses the network. That also means there is no cloud sync and no automatic backup: change phones or uninstall the app and your history does not come with you.

Also included
• Works offline — a timer needs no network connection
• English, Korean, Japanese and Spanish
• Follows your system light or dark theme
• Notifications can be switched off entirely in Settings
• Small download and a fast start: open, press start, put the phone down

Free, with a one-time upgrade
Everything above is free, supported by a small banner under the timer and an occasional full-screen ad. Ads never interrupt a running session: the full-screen ad appears only when you leave the timer to open your statistics, and only after several completed sessions. If you would rather not see them, "Remove ads" is a single purchase of $2.99 — not a subscription — and turns every ad off permanently. It is the only thing sold in the app, and no feature is locked behind it.

Twenty-five minutes is short enough to start and long enough to matter. Press start and let the ring do the counting.
