The silent ADHD focus timer for Apple Watch — haptic time awareness, no clock.
Thrum hides the clock and gives you a gentle, rhythmic pulse instead — a quiet anchor in time that keeps working even when the screen is off. No numbers. No noise. Just focus.
This is the whole focus screen. No clock. No countdown. It tells you the plan — how often the pulse taps, when the heads-up comes — then a gentle rhythm keeps time on your wrist. You never have to look at it.
Apps for focus love to show you a clock. For an ADHD brain, a visible countdown is just one more thing to fixate on — or forget. Thrum takes the opposite path. What time blindness is, and what helps ›
The focus screen hides time by design — never a countdown. It tells you what will happen and how often you'll be tapped, then gets out of the way. Your attention stays on the work, not the timer.
A reliable session keeps pulsing even when your wrist drops and the display sleeps. The session never quietly dies on you.
Three taps you learn in a minute: a soft pulse that marks time, a firmer cue that asks for a small decision, and a heads-up two minutes before the end. Never a shock, never a buzz you'll learn to ignore.
Two modes, gentle transitions, routines, widgets, Apple Health, and an iPhone companion — all speaking the same calm language.
Timed sessions, or an open-ended WatchMinder-style cue mode.
Start a session — and see when one's running — right from your face.
A heads-up before the end, then a choice: I'm ready, or 5 more minutes. Nothing ends on its own.
A quiet prompt at a set time, and a firm tap at each step change. A prompt, never a surprise session.
Set your cue schedule on iPhone; it syncs to your watch. No Watch? Interval cues still reach your iPhone in the background, as a silent vibration.
Optionally save finished sessions as Mindful Minutes. Write-only — Thrum never reads your health data.
Start a 25-minute session from your Home Screen, or ask Siri. Works with Focus automations.
