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.
