What's New

Version 3.24.2·Nov 30, 2025

Seconds for Apple Watch • Added new compact interval template • 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 alert enabling from settings • Fixed watch count down 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.

Now down to 1 star. I PAID for the app and now it is saying that as an UNPAID user, I can only use 1 timer. I'm sorry?! I've used this app for years with no issues. Now all of a sudden the timer just stops. When I restart, it goes for 2 exercises and then stops again 🙄

Does exactly what I want. Easy to use and doesn't require a subscription like many similar apps.

keeps cutting out when my phone (android) receives a notification... not great when you're on a run and want to keep your phone in a pocket.
