# Riduck vs IntervalCoach

The clearest difference is review sentiment: IntervalCoach at 100% against Riduck's 36%. IntervalCoach also leads on update cadence (every 3 days vs every 3 weeks). Riduck's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.8). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. IntervalCoach sells 4 in-app purchases, starting at $2.99 per month. Riduck asks for nothing beyond the download.

Riduck holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 11 respectively. Written reviews complicate that: 36% of Riduck's written reviews are positive against 100% of IntervalCoach's, so the app with the better star average is not the one people write more warmly about.

Riduck ships an update every 3 weeks, IntervalCoach every 3 days. The most recent releases landed on October 7, 2026 and October 12, 2026 respectively.
