Haptic Interval Timer

Feel time without watching the clock. Haptic Interval Timer taps your wrist with a silent vibration cue at the interval you choose, so your hands and eyes stay on what matters.

Built for Apple Watch first: pick a preset, press Start, and lower your wrist. Cues keep arriving with the screen off and the iPhone away.

WHAT IT DOES

• Repeating haptic cues every few seconds, minutes, or hours
• Countdown mode (pomodoros, presentations, workouts, breathwork) or count-up mode (stretching, pacing, rehabilitation)
• Eight named cue patterns to choose from: single, double, and triple taps, rise, fall, alert, success, and warning
• A Test Haptics screen that plays every pattern so you can pick one you can feel before you rely on it
• Saved presets, ready in three taps or fewer from the Watch, plus a complication that starts your last preset instantly
• Pause, resume, reset, and add five minutes without touching your phone
• A Setup screen that checks notification permission and explains every condition that can weaken a cue: silent mode, Theater Mode, Water Lock, wrist detection, Focus, Low Power Mode, and haptic strength

RELIABLE, AND HONEST ABOUT IT

Cues are scheduled ahead of time as local notifications, which is what lets them fire with the display asleep. A distinct alert marks the end of a countdown. The Watch keeps a window of upcoming cues pending and refills it in the background and whenever you open the app. The running screen always shows how far the current window reaches, so you are never guessing whether the next cue is really coming.

There is no sound. Not a quiet sound, none: cues are wrist taps only, so nothing you do here can interrupt a meeting, a class, or a patient.

ACCESSIBLE BY DEFAULT

Every control is VoiceOver labelled, the timer display scales with Dynamic Type, and the transport buttons are full-size tap targets. Cues are tactile, so the app works when sound is not an option, or not available to you.

WHO IT IS FOR

Anyone who needs a repeating silent cue: focus sessions and time blindness, interval workouts and stretching, presentations and teaching, breathwork and pacing exercises, and anyone who prefers or needs tactile rather than audible reminders.

PRIVATE AND OFFLINE

No account. No subscription. No tracking. No analytics. The app contains no networking code at all, so everything stays on your devices and works fully offline. The one-time purchase includes the complete app.

The iPhone companion mirrors your presets to the Watch over the air when both are nearby, and the Watch keeps working entirely on its own.

Note: haptic cues require an Apple Watch. The iPhone app configures presets and previews patterns using the iPhone's own haptics; the cues themselves play from the Watch.
