User Reviews

The app is praised for its simple, free-friendly timer and ability to store several workouts with reliable basic timing. However, recurring complaints center on monetization and paywalls, interruptions that disrupt timing, missing customization options, weak cross-device support and support responsiveness, and a clunky UX/time-format experience.

Pros

Simple, intuitive timer interface that’s easy to use.
Free version provides the core timer functionality and value.
Reliable basic timer that works without unnecessary complexity.
Ability to store and manage multiple timed workouts.
Timely notifications/alerts during workouts.

Cons

Aggressive paywall and free-version limits; many features require purchase.
Timer reliability issues when interrupted (phone calls, other apps, or leaving the app).
Lacks important customization and sequencing features (precise interval lengths, rest between sets, next-interval cue, exercise naming/announcements).
Poor cross-device support and inconsistent data sync; reports of data not carrying over to tablets/Watch and slow/support responsiveness.
Clunky UX and time-format quirks (weird UI patterns and military-time display).

Recent reviews

Most interval apps are incredibly clunky. The interface for this app is very smooth, once you take a couple minutes to learn it — the interface is pretty intuitive, but it won’t hold your hand if you’re having trouble figuring it out. More importantly, after updating this morning, the app isn’t reliably making sounds anymore! I hope they catch this and patch it.

I’ve had this app for quite some time only thing I wish they’d add is individual seconds not just hoping 5-10-15 and after some numbers it skips too much it’d be nice to just type the time needed and for it to go off of that
