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.

Practical and flexible

I have been using Seconds Pro exclusively for eight years now. It has so many useful features. Sure I can program intervals, Tabatas, rest periods, like with many timers. Here are some features I find particularly useful.
1. Text to speech gives me the name of the next exercise without looking at the timer.
2. Copying pasting of individual exercises between timers.
3. Forget my iPad with freshly programmed timers at home? Automatic continuous backups allow me to download the most recent iCloud backup to my iPhone.
4. Use my timers on my Apple Watch.
5. The Quick Intervals on the Apple Watch App is very well designed and permits the quick programming of intervals of several exercises with breaks in a breeze.
6. Easy and intuitive user interface.
This is the best fully featured timer for my needs. I use it on a daily basis.

Worked great the first time I played it, and then the songs wouldn’t play with the intervals.

This looks like a great timer for keeping me contract with the multiple Physical therapy exercise that I get assigned each week. I like that it comes with timer is already set up that I can modify for the specific exercises and timings prescribed by the physical therapist. I found this because I had thought of the idea of choosing a different song for each exercise and playing a clip of it. That is the length of time that I’m supposed to be doing that exercise such as 90 seconds for the first exercise with one song and then two minutes for the next song.

Before finding out about this app, I had tried to set this up manually, using song clips and imovie, but it was becoming really difficult to put the total time elapsed and interval timers visible on top.

A friend did an AI search for me to try to help me find a solution and this app was recommended by AI. So far it looks great. I did figure out how to upload multiple songs to the same timer so it can switch from one song to another. You add the audio to the individual intervals instead of using the ad audio prompt for the whole workout. It was awesome! However, after I did that and played it through once, I never could get any audio (music) to play again with the timer. After the first run through, all I heard were the voice prompts, no music.

Information not syncing after updating software and reset phone

I’ve had this app since 2019 with no problems. Now with new updates, my saved workouts are not syncing to my watch.

Great app

We use the app for everything from exercise, to tanning, to cooking. Very versatile!

I really like it but…

This is probably just me but I can’t seem to sync custom timers across devices (iPhone, iPad and Apple Watch). I don’t understand the ‘Signed in as Anonymous’ idea and when I look at the ‘intervaltimer’ website I end up with more questions - I can’t see how to log in or sync from there either. I have both he Seconds and Seconds Pro app and have paid for whatever I can pay for on both. I’m just confused. I also can’t seem to see a ‘contact us’ option anywhere which is why this review is going on here. Would love to be contacted…

Having said that, it is super easy to create a custom timers and the full colour screen, alerts and being able to use your own music synced to the timers are all great. This would be a 5 star review if I could sort out the above issues. It is only 1 star because I hope the developers will see it, read it and respond to me. Time will tell.
