Focus4Life is a Pomodoro timer, a real task planner and a distraction blocker in one calm app. Its timings and limits come from published research and from the original authors of each technique — the research-backed settings carry an (i) with the source behind them.

FOUR FOCUS RHYTHMS, EACH WITH A REASON
• Classic — 25 / 5 / 15 min, Cirillo's original Pomodoro Technique
• Deep Work — 50 / 10 / 30 min, after Cal Newport's "Deep Work"
• Sprint — 15 / 3 / 10 min, a low-resistance way into a hard task
• Ultradian — 90 / 20 min, the Basic Rest-Activity Cycle (Kleitman; Lavie)
Pro adds fully custom durations.

FOCUS LOCK — IT ACTUALLY STOPS YOU
• Flip to focus — put your phone face-down to work. Pick it up mid-session and it buzzes until you set it back down, even with the app closed
• Block distracting apps — open one mid-session and you meet a calm "Return to focus" screen, or a firm shield that holds until the session ends. You pick the apps, and you pick how firm
• Quiet notifications — Do Not Disturb switches on while you focus and off when you stop. Your own Do Not Disturb exceptions are left exactly as you set them, and the end-of-phase cue still reaches you
Focus Lock only ever runs during a focus phase — never during a break, never while you're paused, and never without a permission you granted yourself.

A REAL TASK PLANNER, NOT A CHECKLIST
• Priorities, due dates and repeats — daily, weekdays, weekly or monthly, ending never, on a date, or after a set number of times
• Estimate a task and the app works out how many pomodoros it needs
• Today, Week and Month views. On tablets and Chromebooks, Week and Month list your actual tasks under each day
• Notes on any task
• A gentle heads-up when one task passes two hours, and a prompt to split anything past four — deep focus has daily limits (Boksem & Tops; Ericsson)
• Nothing reschedules itself behind your back. Overdue work is a count and a button, never a scolding

PROJECTS WITH SOMETHING TO FILL
Group tasks into colour-coded projects, each with an optional note on when and where you'll do the work — an “implementation intention”, shown to make follow-through markedly more likely (Gollwitzer, 1999). Give a project a goal image, estimate its tasks, and the image uncovers itself as you focus your way through the estimate.

A GARDEN THAT REMEMBERS
Every finished session uncovers part of a hidden picture, and longer sessions uncover more. It is a quiet record of effort — not a leaderboard, and not a plant that dies if you take a day off. Missing a day never takes anything away.

HONEST STATS
Minutes focused, sessions completed, tasks done, and your longest single session — for today and the last 7 days. Pro adds 30-day and all-time history, plus a breakdown of which apps interrupted you.

BUILT FOR FOCUS, NOT FOR YOUR DATA
• Local-first — no account, no sign-up, nothing in the cloud. Your data stays on your device
• No ads, anywhere, ever
• Light, dark and system themes
• English and Tiếng Việt
• Phone, tablet and Chromebook — and there are Mac and Windows apps too

FREE, AND PRO
Free covers the whole core loop: unlimited focus sessions, all four research presets, the entire task planner with repeats and notes, two projects, the Garden, and flip-to-focus.

Pro is a one-time purchase — no subscription, no recurring fee — and unlocks unlimited projects, app blocking and Do Not Disturb, 30-day and all-time stats, custom timer durations, and your own photos in the Garden. It comes with a 7-day trial that asks for no payment card and simply ends.

Whether you're studying for exams, working remotely against a wall of notifications, guarding deep work, beating procrastination, or you simply concentrate better in clear intervals, Focus4Life helps you focus without the anxiety.
