What's New in Seconds 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 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.

Great App for Fitness instructors!

Love this app, my co-workers and I use it all the time, for a variety of different fitness classes and workouts. Love that you can copy and paste a workout to create a new one without starting over.

Too many bugs/freezes

I really like this app for programming the workout and classes I teach. However, on my Apple Watch, after I finish one class, I’m unable to go and pull up the next workout because it just spins and spins. I have to completely shut down my Apple Watch in order to get it to reset which is annoying.

Please Fix Widget Issue

Already paid for the app, but when click a preset timer from the lock screen widget, the app would open and direct to a screen page that says non-member can only use the timer set for once. Reclaim purchase and delete and recreate timers do not help, and there’s also no other way to reach out for feedback or assistance. So just leaving a review at here, and hopefully this issue will get addressed soon. Thank you!

Awesome but one recommendation

I love this app as a coach but I would love if there were different voices for the text to speech. Something more motivating than the Siri voice

Super simple, easy to use - could use some flexibility in custom timers. still a 5/5

This interval timer app works just as well as any physical timers if you’re a person that doesn’t mind running an app. Though even with some of the features lacking customizations to utilize in a custom timer. I’m still able to put together the timer I needed for my routine. If they gave the customization more flexibility instead of having to copy paste tediously and in addition to alternative music option for the audio… I’d give this app 10 stars if I could. foreals!
