Verdict

The call

The clearest difference is ads: Gymboss Interval Timer at none against Workout Timer's shown. Gymboss Interval Timer also leads on rating (4.7 vs 4.4) and ratings volume (797 vs 50). Workout Timer's advantage is review sentiment (61% vs 37%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Gymboss Interval Timer sells 3 in-app purchases, starting at $1.99 per year 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.

ReceptionRating · Positive reviews · Number of ratings

Gymboss Interval Timer holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Gymboss Interval Timer has 797 ratings behind it against 50, so its average is the more settled of the two. Written reviews complicate that: 37% of Gymboss Interval 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.

UpkeepUpdate frequency

Gymboss Interval Timer ships an update every 5 weeks, Workout Timer every 3 weeks. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
