What's New in Seconds Pro Interval Timer

25.3

September 26, 2026

25.0 No new features this time. This release is maintenance work behind the scenes, and everything works exactly as it did before. 25.1 Creating an account with Google, and signing in with one, work again in the free app. 25.2 The tabs at the bottom of the screen no longer disappear after you edit a timer. 25.3 Apple Watch now fetches your timers and settings from iPhone. Request Sync is at the top of the watch's Settings, and My Timers fetches them the first time you open it. Sync Timers Now has gone from the Apple Watch settings on iPhone.

User reviews

3rd review, comments are mainly for watch app

Just bought new iPhone and new Watch; I use this app on my Watch when I train, so my comments do not concern the performance on the iphone. My biggest issue is the syncing between the iPhone and the watch. It is a little bit of hit and miss, might take 2-3 times to sync correctly. Also, after an afternoon of research on gemini, I learned that if you put your training intervals into a folder, it just does not sync, you need to put them on the “home” page for them to sync with your watch.
I also wish there were more flexibility for the sound selection when you start and end an interval.

Finally, there is no compilation available, so I had to use a workaround by creating a shortcut and adding it to my watch face.
In summary, the previous version on my watch series 5 was much better.
————————-
Previous review: Unfortunately, I have to change my rating from 5 stars to one star. I was hoping that the developer would fix the fact that the app is not working on my apple watch series 5 anymore but I read the latest update and it seems clear that he will not fix it. There are a lot of similar apps on the store and most of them works with the watch series 5. For me the app becomes useless since it needs to work on my watch, as I don’t want to bring my phone to the gym when I use it.

Following is my original post of 5 years ago where I gave 5 stars: I like this app. You can set up almost any workout that you want. There are a few little things that I wish they would add. The countdown menu has less options than another app that Runloop makes, the Strech App (which is free). In the Strech app, you have the option of making each countdown repeat when the time has expired, which you cannot do in the Seconds App. Also, if you want to change the time for any countdown, you need to go to Settings; it would be easier if it could be done directly. I like the Quick Intervals option on the watch, but I wish it could remember the last set up. Currently, you need to set it up each time you use it. But overall, very good app, very versatile.

It just works

You *can* get as complicated as you wish. *Or* you can just set simple timers or routines that guide, and not stress out. Works either way. Highly recommend for anyone considering adding “timers” to their stretching, exercise, or practice regimen.

Very Intuitive

I definitely recommend this timer. The interface is easy to read and the audio cues worked with my AirBuds without fuss. I can play music and the timer still provides cues. This app works like it is super to do.
