Verdict

The call

The clearest difference is rating: Intervals Pro at 4.8 against NetGym App's 4.2. Intervals Pro also leads on review sentiment (85% vs 57%) and ratings volume (14K vs 6). NetGym App's advantage is in-app purchases (none vs 8) and iOS requirement (15.1 vs 17.5). On price, update cadence, ads and device support there is nothing between them.
