5/5This app is really great for multiple reasons
I’ve been using Seconds Pro now for 4+ years. I purchase workout routines from various trainers (typically in 8-12 week segments), and I program them into the app utilizing custom timers. Over the years, I’ve fine tuned the style and look to suit my needs, and this app has accommodated everything I’ve wanted to do when creating these timers. I’ve also recently purchased an Apple Watch, and I use the Seconds Pro app on there during my actual workouts…it is incredibly helpful to have the intervals on my wrist while listening to the countdowns and up next announcements in my AirPod Pros…purchasing 8-12 week segments and having them programmed into this app keeps me on track and accountable to myself during the workouts as well as keeping me on track to each week’s programming allowing me to finish and keep progressing; this has been a critical part of my consistent training over time. (Hint: this is the key to fitness folks) I’m writing this review as a genuine thank you to the developers of this app…this has been and continues to be the perfect tool for me. Thank you!

1/5Ok timer that’s now bad
This was an ok timer. I was able to set up various workout routines. But in past 6 months, there’s been multiple issues. Some are minor but critical issues are: 1. Some intervals will randomly pause with 3 seconds left. Then about 5 seconds later, it would speed through the countdown 3-2-1-go within half a second. I know it’s not my device because it happened on multiple devices and the music still plays without pausing. 2. In past several months, if I have the music on then launch this app, the music volume would go down. Most of the time, during the first interval, the music would go back to the volume I had set before launching the app. But sometimes the music would stay low. i have to force close the app and music, then try again few times until I can hear the music. 3. Sometimes you can’t hear the countdown to an interval. So I’m having to keep an eye on the timer. I tried changing my settings, try on my iPhone vs iPad, etc but doesn’t fix it. Really frustrating if I am out for a run, again having to force close the app and music, then try again few times until I can hear anything. It was worth the $ I paid back then, but I would be very unhappy having to pay for this now.

4/5Almost great!
I’ve used Pro version of this app for over 5 years now and have created 150 interval timers that are essentially copies or modified versions of TrainerRoad workouts. I use them for training for kayak racing. Once you make about 10 timers you slowly pick up the built in shortcuts that are pretty cool. I can program even a fairly complex TR workout in about 5 min that took me 20 min when I was learning. Unfortunately there are 2 app problems. When you try to edit an app your changes are not saved. As soon as you close the edit process the timer reverts back to it’s original form. The only solution I’ve found is to delete the original and create a whole new timer. Thankfully that’s much easier for me than it used to be but still it’s annoying. The second problem is I can find no way to contact the developer to report this and ask if there is a solution. Read the manual page and no option on it to ask for help. Help option here leads to that manual page. Not even an email address. Lost a star for no support and that bug.

5/5Feature request
Please make it so that when I leave the app for a few minutes then come back the interval counter and timer is not reset. I like to be able to know the sum of all the intervals I have done in the entire day. Great app for practice questions in medical school and keeping pace. Text to speech is something only this app offers for the interval ending notification. Rich with features— other interval timers didnt work. Could be used for wokiny out. I would love to be able to leave my practice wiestion timer, do an interval workout, then come back to the practice questions without lost progress of my counter. 1) dont let the progress be lost for my current session if I go yo another app for a whole (opt-in feature so it doesnt disturb others) 2) let me pause an interval for a while, work on another interval timer, then come back later and resume the session. (Opt-in feature so it doesnt disturb others)

1/5Serious Version Update PROBLEMS
Overall I have loved this app for the 3 years I have used it as a fitness professional. Would have highly recommended until this week BUT the latest Apple update seems to have wreaked havoc on the app’s functionality. Until the app developer can fix whatever problems have resulted, the app is completely useless on an Apple Watch AND also frustrating to create or edit existing custom timers on an Apple iPhone. Watch literally will not load data. Phone has a problematic overlap between bottom task bar that list app options like ‘folders’ with the in-timer bottom task bar options like ‘cut’ and ‘copy’. Please fix. Fitness professionals have been using this app for years and without an IMMEDIATE UPDATE we will flock to the next best app, continue to write negative reviews for this app, and likely never return. UPDATE 16Nov2025: version update has fixed phone cut/copy/paste toolbar functionality BUT the watch still DOES NOT have any functionality whatsoever. Preexisting timers visible on the phone are completely absent from the watch, as if the app on the watch is merely a shell with zero contents.

SDK Updates
3.24
New Apple Watch app! As has been pointed out, the latest update to watchOS 26 broke the existing Apple Watch app. The previous version was developed when Apple Watch was first introduced and many workarounds were required to get something that behaved as I wanted. Apple changed how they wanted developers to build apps several years ago and the old version of the watch app and this approach were incompatible, but the new approach was also a step back in many ways and some features were not possible. This led to difficulties updating the app. The issues relating to watchOS 26 and the previous version of the app have meant that I have had to redevelop the app from the ground up. This means that finally some features that people have been requesting are now included in the app where they were not possible before. But it also means that, in the short term, there may some missing features and inconveniences. These will be ironed out over time. My priority has been to get a working version of the Apple Watch app ready as quickly as possible so that users are still able to use it for their training.
3.24.1
Thank you for your feedback on the previous version. This update resolves: - Apple Watch navigation issue - Cut & Paste toolbar hidden - Apple Watch timer sort order If these improvements have addressed your concerns, we would greatly appreciate an updated rating.
3.24.2 · 30 Nov 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.

          "body": "I’ve been using Seconds Pro now for 4+ years. I purchase workout routines from various trainers (typically in 8-12 week segments), and I program them into the app utilizing custom timers. Over the years, I’ve fine tuned the style and look to suit my needs, and this app has accommodated everything I’ve wanted to do when creating these timers. I’ve also recently purchased an Apple Watch, and I use the Seconds Pro app on there during my actual workouts…it is incredibly helpful to have the intervals on my wrist while listening to the countdowns and up next announcements in my AirPod Pros…purchasing 8-12 week segments and having them programmed into this app keeps me on track and accountable to myself during the workouts as well as keeping me on track to each week’s programming allowing me to finish and keep progressing; this has been a critical part of my consistent training over time. (Hint: this is the key to fitness folks) I’m writing this review as a genuine thank you to the developers of this app…this has been and continues to be the perfect tool for me. Thank you!",

          "body": "This was an ok timer. I was able to set up various workout routines. But in past 6 months, there’s been multiple issues. Some are minor but critical issues are: 1. Some intervals will randomly pause with 3 seconds left. Then about 5 seconds later, it would speed through the countdown 3-2-1-go within half a second. I know it’s not my device because it happened on multiple devices and the music still plays without pausing. 2. In past several months, if I have the music on then launch this app, the music volume would go down. Most of the time, during the first interval, the music would go back to the volume I had set before launching the app. But sometimes the music would stay low. i have to force close the app and music, then try again few times until I can hear the music. 3. Sometimes you can’t hear the countdown to an interval. So I’m having to keep an eye on the timer. I tried changing my settings, try on my iPhone vs iPad, etc but doesn’t fix it. Really frustrating if I am out for a run, again having to force close the app and music, then try again few times until I can hear anything. It was worth the $ I paid back then, but I would be very unhappy having to pay for this now.",

          "body": "I’ve used Pro version of this app for over 5 years now and have created 150 interval timers that are essentially copies or modified versions of TrainerRoad workouts. I use them for training for kayak racing. Once you make about 10 timers you slowly pick up the built in shortcuts that are pretty cool. I can program even a fairly complex TR workout in about 5 min that took me 20 min when I was learning. Unfortunately there are 2 app problems. When you try to edit an app your changes are not saved. As soon as you close the edit process the timer reverts back to it’s original form. The only solution I’ve found is to delete the original and create a whole new timer. Thankfully that’s much easier for me than it used to be but still it’s annoying. The second problem is I can find no way to contact the developer to report this and ask if there is a solution. Read the manual page and no option on it to ask for help. Help option here leads to that manual page. Not even an email address. Lost a star for no support and that bug.",

I like to be able to know the sum of all the intervals I have done in the entire day. Great app for practice questions in medical school and keeping pace. Text to speech is something only this app offers for the interval ending notification. Rich with features— other interval timers didnt work. Could be used for wokiny out. I would love to be able to leave my practice wiestion timer, do an interval workout, then come back to the practice questions without lost progress of my counter. 1) dont let the progress be lost for my current session if I go yo another app for a whole (opt-in feature so it doesnt disturb others) 2) let me pause an interval for a while, work on another interval timer, then come back later and resume the session. (Opt-in feature so it doesnt disturb others)",

          "body": "Overall I have loved this app for the 3 years I have used it as a fitness professional. Would have highly recommended until this week BUT the latest Apple update seems to have wreaked havoc on the app’s functionality. Until the app developer can fix whatever problems have resulted, the app is completely useless on an Apple Watch AND also frustrating to create or edit existing custom timers on an Apple iPhone. Watch literally will not load data. Phone has a problematic overlap between bottom task bar that list app options like ‘folders’ with the in-timer bottom task bar options like ‘cut’ and ‘copy’. Please fix. Fitness professionals have been using this app for years and without an IMMEDIATE UPDATE we will flock to the next best app, continue to write negative reviews for this app, and likely never return. UPDATE 16Nov2025: version update has fixed phone cut/copy/paste toolbar functionality BUT the watch still DOES NOT have any functionality whatsoever. Preexisting timers visible on the phone are completely absent from the watch, as if the app on the watch is merely a shell with zero contents.",
