Verdict

The call

The clearest difference is ads: Intervals Pro at none against Go&Rest's shown. Intervals Pro also leads on ratings volume (14K vs 8) and update cadence (every 8 days vs every 3 weeks). Go&Rest's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (15.1 vs 17.5). On price, rating, in-app purchases and device support there is nothing between them.
