Comments on Seconds Pro - Interval Timer for Android

★★★★★ Aimee Lyons · Dec 12, 2025

Great for interval workouts and can still listen to music. Love the talk with countdown alarm option.

★★★★★ Margarita Lane · May 30, 2026

Subscribed to an exercise app, easy to export the timers they give me to seconds pro so icanhave a different workout every day. Haven't tried myself to make my own timer sequence so can't comment on this. Would be amazing if I could synch it to my Garmin watch, that would be next level!!!

★★★★★ Michael Sevier · Jul 20, 2026

Use it all the time for interval training and stretching/yoga great - love using it for stretching and meditation.

★★☆☆☆ Mig N · Jun 10, 2025

Poor updates, app not set up for Android bottom navigation buttons anymore

★☆☆☆☆ Stephen Murrish · Aug 3, 2025

I paid for the pro version. The app is now not allowing me to use it, saying I need to upgrade. The option to upgrade says "upgrade unavailable." the app is unusable. And I paid for it.

★☆☆☆☆ Philip Himmelstein · Jun 29, 2025

Timers are broken & loop when adding default beeps or custom audio. Went ahead and requested a refund after recent reviews cite no response from developers. Do not download the app on Android as of 6/29/25 until the developers note explicitly these issues are resolved.

Trust & Safety: The app requests standard permissions for network access, foreground service, notifications, storage, and ad IDs. This set aligns with typical timer apps and supports features such as background operation, music integration, and timer sharing; no unusually invasive permissions are requested.
