User Reviews

Overall, Seconds Pro is praised for its high customizability, class-ready workflows, and a straightforward, low-friction experience, plus a one-time purchase model and solid backups. However, multiple reviews report recurring reliability problems with Apple Watch syncing and complications, timing glitches during workouts, and occasional failures to save workouts to Health data, especially after updates. These issues can disrupt live sessions, though the core features remain valuable for planning and delivering timed workouts. The app shows strong potential with continued stability improvements on watchOS and iOS.

Pros

Highly customizable timers and routines; easy to set up.
Great for workouts and group classes; ideal for trainers.
Robust backups and data recovery; cross-device syncing (iCloud) and offline functionality.
One-time purchase with no ongoing subscription.
Simple, intuitive interface with large clear controls.

Cons

Unreliable Apple Watch integration and complications; syncing issues and difficulties adding to watch faces.
Timing glitches: beep irregularities and countdown inaccuracies.
Saving workouts/Health data can hang or fail at the end of a session.
Stability issues after OS/watch updates; occasional crashes and sync failures.

Recent reviews

If you need timers for exercise, or potentially many other uses (sports, competition, ...) this is the best I've found. Best features and customization around behavior, appearance and audio. Lots of templates and the ability to easily design and edit any pattern you want.

I use this almost every day when I workout. Easy to create your own routines. As an added bonus, it backs up data so in event of major crash you can restore your data and go on with your workouts with out trying to remember what you created. I also like that it has a great backup. My only regret is I have have not figured out how to combine different times into one workout.

Helps me stay on track with my classes, ppl love the creativity and it allows me to focus on cueing and the flow. Thanks for this great customizable app. Sometimes takes a few times to sync with Apple Watch. Also is there a way to sync app with Mac and copy/paste from Excel into here? Is there a way to pick and choose what timers to send to Apple Watch? Can you create folders to group timers? Can you set up personalized defiant custom timers? Can you change vibration for 15 second reminder before next interval?
