Verdict
The clearest difference is ads: Onyx Timer at none against Workout Timer's shown. Onyx Timer also leads on iOS requirement (7.0 vs 15.1). Workout Timer's advantage is rating (4.4 vs 4.1) and ratings volume (51 vs 16). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Onyx Timer sells 1 one-off in-app purchase and Workout Timer sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Workout Timer holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 16 and 51 respectively. Written reviews complicate that: 65% of Onyx Timer's written reviews are positive against 61% of Workout Timer's, so the app with the better star average is not the one people write more warmly about.
Onyx Timer ships an update every 2 weeks, Workout Timer every 3 weeks. The most recent releases landed on September 30, 2026 and October 20, 2026 respectively.
