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.

Importing Won't Work

I upgraded my device and now when I try to share time, it will not automatically import. I can pull it up on the web browser, but there is no option to "open in the app" also, the most frustrating part is there is no way to reach out to anyone for help.

I love this app

This app really does its job well. I use it to get to two minute dead hangs. I use a 10 second warm-up to get to Bar and get into position. I then do 30 seconds with a countdown and then staying on the bar doing a low intensity of one second and then doing a 30 second high intensity again.

What I Like are the alerts at 15 seconds and the countdown at three seconds although I would rather have it count at 10 second intervals and countdown 54321

This app is a very good app for the price

Love the app but…

I had all of my timers saved and didn’t use the app for a few months. Opened it and they’re all gone. No way to contact support and get help.
