Verdict

The call

The clearest difference is monetization model: GymTimer at free with in-app purchases against Interval Timer's subscription. GymTimer also leads on review sentiment (100% vs 67%) and update cadence (every 4 days vs every 4 weeks). Interval Timer's advantage is ads (none vs shown) and ratings volume (3.6K vs 2). On price, in-app purchases, device support and iOS requirement there is nothing between them.
