# ZenWorkout vs AI Workout Timer

The clearest difference is monetization model: ZenWorkout at free with in-app purchases against AI Workout Timer's subscription. ZenWorkout also leads on update cadence (daily vs fortnightly) and iOS requirement (13.0 vs 15.1). AI Workout Timer's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. ZenWorkout sells 1 in-app purchase, starting at $0.99 per month and AI Workout Timer sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ZenWorkout ships an update daily, AI Workout Timer fortnightly. The most recent releases landed on September 14, 2026 and September 17, 2026 respectively.
