Planck Timer is a focused time tracker for people who want to know where their hours actually go. Clock in and out of tasks with a single tap, run multiple timers at the same time, and see honest reports across your week, month, and year. WHY PLANCK TIMER Most time trackers force you to pick one thing at a time. Real work isn't like that. You start a deep work block, then a build kicks off and you start reading docs while it runs. Planck Timer handles concurrent tasks the way your day actually works. FEATURES • Concurrent timers run as many tasks at once as you want • One tap to start, one tap to stop • Categories with custom colors so reports read at a glance • Week, month, and year views with stacked bars and per-task totals • Full history grouped by day, with quick edits and manual entry • Trim idle time on a running entry without losing the start • Private iCloud sync between iPhone, iPad, and Mac (your data, your account) • Native dark interface designed for long sessions • No accounts. No subscriptions. No ads. No analytics.

Flip your phone face down. The timer starts. Lift it, and the timer stops. Flip Focus is a deep work timer for people who are tired of promising themselves they'll concentrate. There is no honour system here and no button to press when you get distracted. The session is physically bound to your phone: face down on the desk, you are working. In your hand, you are not. WHY THIS ONE HOLDS UP Every other focus timer runs happily in your pocket while you scroll something else. This one cannot. Flip Focus reads your phone's motion sensors and only accumulates time while the phone is actually face down. You cannot quietly cheat a session, which is precisely why the hours in your history mean something. START IN ONE MOVE Choose a session and flip. That is the entire ritual. No setup to work through every time you sit down, no timer to remember to start, no excuse to open the phone "just to begin". BLOCK EVERY DISTRACTING APP While a session runs, Flip Focus uses Screen Time to put your distracting apps behind a lock screen. It works as an allowlist rather than a blocklist: everything is blocked except what you deliberately permit, so a newly installed app cannot slip through a gap you forgot to close. AUTO-PAUSE KEEPS YOU HONEST Pick the phone up mid-session and the timer pauses itself and tells you to put it back down. Your streak is not broken by the pause; it is broken by pretending the pause never happened. Flip Focus simply refuses to pretend. QUITTING TAKES A MOMENT Ending a session early is still possible, it just isn't two taps any more. You copy out a short passage that makes the case for staying, then hold a button for a few seconds. Neither step is hard, and the way out is always there when you genuinely need it. It simply stops being something you can do without thinking. Most urges to quit don't survive the minute it takes. SESSIONS THAT MATCH REAL WORK Start from ready-made blocks for deep work, quick focus, study and creative work, or build your own with the length, name and colour that suit how you actually work. Long, uninterrupted blocks for hard problems. Short ones for clearing the deck. SEE WHERE THE TIME WENT After every session, mark how it went. Every minute you stay face down earns focus points, and your dashboard tracks your daily streak, personal bests, total focused time and success rate. Tap any session to turn it into a share card for your friends. Because the timer cannot be gamed, every number is real. BUILT TO STAY OUT OF THE WAY A Live Activity keeps the countdown on your Lock Screen so you can check the time remaining without unlocking anything. Haptics confirm the start and finish of a block. The app is quiet, quick and does not ask for your attention while you are trying to give it to something else. WHO IT IS FOR Engineers, writers, designers, founders, analysts, researchers, students — anyone whose output depends on long stretches of uninterrupted attention, and whose phone is the single largest threat to getting them. If you have tried focus apps before and drifted away from them, the reason is usually the same: they asked you to be disciplined about the tool itself. Flip Focus asks for one physical action, once, at the start. The desk does the rest. Flip the phone. Do the work.
