What's New in Seconds Pro Interval Timer

3.24.2

November 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.

Hands down the best fitness app

Being able to create my own workouts, using my own music, tailoring ever prompt and interval to my own needs, has been a total game-changer on my fitness journey. All of the other fitness apps have so much noise, and they end up being overcomplicated….which means I just don’t use them! Seconds is actually a pleasure to use, very easy to manage, and within a couple of clicks I am off and running (or lifting, or walking, or yoga-ing, or whatever I have planned for the day!) Thanks so much.

A few requests: allow folders to be shown in the widget, allow a timer’s audio to be turned off only for one interval (like at the end of yoga, for shivasana, for example), and give us a user-generated template library where we can add or download timers created by each other!
