Verdict
The clearest difference is ratings volume: Intervals Pro at 14K against FitMate HIIT Stopwatch's 14. Intervals Pro also leads on rating (4.8 vs 4.4) and update cadence (weekly vs every 5 weeks). FitMate HIIT Stopwatch's advantage is iOS requirement (11.0 vs 17.5). On price, ads, in-app purchases and monetization model there is nothing between them.
