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

I love how you can customize the timers to fit your needs and also that your music isn’t interrupted when starting, stopping and using the timer.

Seconds Pro makes my life easier as an OTF coach. Having it vibrate on my arm to remind me a change is coming up so I can better focus on a member without constantly checking the time allows me to level up as a coach and give our members me a better experience.
