Verdict

The call

Interval Timer and GymTimer both sit at 4.8 stars, but that hides the real split: 100% of GymTimer's written reviews are positive against 73% of Interval Timer's. GymTimer also leads on update cadence (every 4 days vs fortnightly). Interval Timer's advantage is ratings volume (297 vs 2) and device support (4 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
