Verdict
The clearest difference is in-app purchases: Ace Workout at none against 1RM Calculator's 3. Ace Workout also leads on update cadence (fortnightly vs every 4 months) and iOS requirement (11.0 vs 15.0). 1RM Calculator's advantage is ratings volume (130 vs 3) and review sentiment (100% vs 80%). On price, rating, ads and device support there is nothing between them.
