Getting started
- Open Haptic Interval Timer on your Apple Watch.
- Allow notifications when asked. That permission is what lets the Watch tap your wrist while the screen is asleep.
- Open Test Haptics and tap each pattern until you find one you can feel reliably.
- Go to Presets, pick one, and press Start. Lower your wrist; cues keep arriving.
The two modes
Countdown runs for a fixed duration and ends with a distinct completion pattern. Use it for focus blocks, presentations, workouts, and breathwork. Count up runs until you stop it. Use it for stretching, pacing, and rehabilitation, where the cue matters and the end time does not. In both modes the cue repeats at the interval you set, from seconds up to hours.
During a session
Pause and Resume hold and restart the session without losing elapsed time. +5m adds five minutes to a countdown while keeping cues aligned to their original interval, so the rhythm never shifts. Reset stops the session and clears elapsed time.
If the Watch restarts or the app is force-quit mid-session, the session is restored as paused with your elapsed time preserved. Tap resume to continue. To start your last preset instantly, add the Haptic Interval Timer complication to your watch face.
If a cue feels weak or is missing
These are the conditions that can suppress or weaken a wrist tap. The Setup tab in the app checks notification permission for you and lists the rest.
| Condition | What it does |
|---|---|
| Silent mode | Haptic alerts still fire. Sound is muted; taps are not. |
| Theater Mode | Mutes display and sound. Haptics still fire when notifications arrive. |
| Water Lock | Touch is locked but haptics still fire. Turn the crown to unlock. |
| Wrist Detection | Must be on, or wrist-down alerts are silenced. Settings → Passcode → Wrist Detection. |
| Focus modes | Allow this app's notifications in your Focus settings, or cues are held while a Focus is active. |
| Low Power Mode | Reduces background work. Cues still deliver, but keep sessions under an hour for best results. |
| Haptic strength | Settings → Sounds & Haptics → Haptic Strength. Raise it if cues are hard to feel. |
| Notifications denied | Watch Settings → Notifications → Haptic Interval Timer, and allow them. |
If cues still do not arrive, restart the Apple Watch. That clears a stale notification queue more reliably than reinstalling.
How reliability works
Upcoming cues are scheduled ahead of time as local notifications, which is what lets them fire with the display asleep and the iPhone away. The Watch keeps up to 56 cues pending at once, below the system limit, and refills that window automatically as cues fire and whenever you open the app. All scheduling uses absolute times, so a time-zone change or a daylight-saving transition cannot shift a cue.
Common questions
Does it need my iPhone?
No. The Watch app is standalone. The iPhone app only makes editing presets easier on a bigger screen, and mirrors them across when both devices are nearby.
Can the iPhone tap my wrist?
No. Cues play from the Apple Watch. The iPhone's Test haptics screen uses the iPhone's own haptics so you can rehearse the pattern vocabulary; the real cue is the Watch's.
Do I need an Apple Watch?
Yes, for the cues themselves. The app is built around the Watch's haptic engine.
How many patterns are there?
Eight cue patterns — single, double, and triple taps, rise, fall, alert, success, and warning — plus a distinct completion pattern that marks the end of a countdown.
Is there a subscription?
No. Haptic Interval Timer is a US$0.99 one-time purchase with no subscription, in-app purchase, ads, or sign-in.
Does it collect any data?
No. The app has no networking code and works fully offline. See the privacy policy.
Will my presets move to a new Watch?
Presets live on each device. Open the iPhone companion near your new Watch and they mirror across.
Can I report a missed cue?
Yes, and it is the most useful thing you can send. Include whether Low Power Mode, a Focus, or Theater Mode was active at the time.
