## Review summary

Users praise Seconds Interval Timer for its strong customization, easy-to-use interface, ability to preset workout timers, audio alerts, and a one-time purchase model. However, recurring complaints center on Apple Watch support problems (watch complications missing, syncing issues), data loss where saved timers disappear, and confusing purchase/upgrade/restoration processes. Other recurring issues include a countdown timer bug and mixed or slow developer support with few tutorials. Overall, the app is highly regarded for tailoring workouts, but reliability across devices and clear purchasing support need improvement.
