# Ace Workout vs 1RM Calculator

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.

Both are free to download. 1RM Calculator sells 3 in-app purchases, starting at $1.99 per month. Ace Workout asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Ace Workout against 4.9 for 1RM Calculator. That said, the two scores are not equally well evidenced: 1RM Calculator has 130 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 80% of Ace Workout's written reviews are positive against 100% of 1RM Calculator's.

Ace Workout ships an update fortnightly, 1RM Calculator every 4 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
