Verdict

The call

The clearest difference is ads: Intervals Pro at none against Workout Timer's shown. Intervals Pro also leads on rating (4.8 vs 4.4) and ratings volume (14K vs 50). Workout Timer's advantage is iOS requirement (15.1 vs 17.5). On price, in-app purchases, monetization model and device support there is nothing between them.
