Seconds Interval Timer25.4 - App Store

Seconds is an interval timer for HIIT, Tabata, EMOM, circuits and any workout built from timed intervals. It calls each interval out loud, keeps running with the screen off, and runs on iPhone, iPad and Apple Watch.

Apple has featured it, and Joe Wicks, The Body Coach, has said it is the fitness app he uses more than any other.

BUILD ANY WORKOUT

- Start from a HIIT, Tabata or circuit template, or build a timer from scratch with sets, rounds and intervals of different lengths.
- Chain timers into one compound timer, so a warm-up flows into the main set and then a cool-down.
- Color-code every interval so you know what is coming before the beep.
- Share a timer with a friend in one tap.

HEAR IT, DON'T WATCH IT

- Voice cues call out each interval by name and warn you before the next one starts.
- Beeps and bells are there too if you would rather not be talked at.
- Play your own music, per timer or per interval. Cues duck the music and it comes back up when they are done.
- The timer keeps going in the background while you use other apps or the screen sleeps.

ON THE GYM FLOOR

- A full-screen, color-coded display you can read from across the room, in portrait or landscape. On iPad it uses the whole screen.
- A lock button stops a stray tap from pausing your set.

APPLE WATCH

- Seconds runs on the watch by itself, so the phone can stay in the locker. Timers you build on the phone sync to the wrist, and Quick Intervals builds a basic circuit on the watch itself.

MORE TIMERS

- A stopwatch that marks your best and worst laps.
- A countdown timer with five preset durations (three on Apple Watch).

APPLE HEALTH

- Save workouts and mindful sessions to Health. With a heart rate monitor connected, Seconds reads your body measurements and year of birth from Health to estimate calories burned.

FREE TO TRY, ONE PAYMENT TO UNLOCK

- Everything is available from the first launch. Build any timer and run it.
- Each timer locks after you run it once. A single in-app purchase removes the lock on every timer you make.

SECONDS AND SECONDS PRO

- Seconds Pro is the same app, paid once up front, with nothing to unlock. The two are separate products and a purchase in one does not carry over to the other. If you bought Seconds Pro, download Seconds Pro. If you bought the unlock in Seconds, download Seconds and use Restore Purchases.

- Added new setting for intervals template
- Added option to remove the info bar during workouts
- Added link to Settings from timer controls
- Added option to exit to the home screen
- Restored haptic feedback only alerts
- Restored haptic feedback to all alerts
- Fixed volume control from settings

- Fixed watch countdown timer not using user defined times
- Fixed delay of alerts and haptic feedback
- Fixed indefinite intervals
- Updated minimum supported watchOS to version 26

watchOS 26 introduced changes that made the previous version of Seconds for Apple Watch stop working. Unfortunately, there was no way to fix it—I had to rebuild the watch app from scratch.

In order to function as expected, the app now requires watchOS 26. This means Apple Watches older than Series 6 are no longer supported—I'm sorry if this affects you. All Series 6 and newer watches can update to watchOS 26 (you may also need iOS 18 on your iPhone).

If these improvements have resolved any issues you had, an updated review would mean a lot. 3.24.2 11/30/2025 Thank you for your feedback on the previous version. This update resolves:

- Apple Watch navigation issue
- Cut & Paste toolbar hidden
- Apple Watch timer sort order

If these improvements have addressed your concerns, we would greatly appreciate an updated rating. 3.24.1 11/16/2025 New Apple Watch app!

As has been pointed out, the latest update to watchOS 26 broke the existing Apple Watch app. The previous version was developed when Apple Watch was first introduced and many workarounds were required to get something that behaved as I wanted. Apple changed how they wanted developers to build apps several years ago and the old version of the watch app and this approach were incompatible, but the new approach was also a step back in many ways and some features were not possible. This led to difficulties updating the app.

The issues relating to watchOS 26 and the previous version of the app have meant that I have had to redevelop the app from the ground up. This means that finally some features that people have been requesting are now included in the app where they were not possible before. But it also means that, in the short term, there may some missing features and inconveniences. These will be ironed out over time. My priority has been to get a working version of the Apple Watch app ready as quickly as possible so that users are still able to use it for their training. 3.24 11/03/2025 SDK Updates 3.23 08/26/2025 - Haptic feedback in iPhone app now stronger with different feedback at end of timers.
