# MR vs Clockwork

The clearest difference is rating: Clockwork at 4.4 against MR's 3.5. Clockwork also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (24 vs 6). MR's advantage is in-app purchases (none vs 1) and review sentiment (55% vs 43%). On price, ads and device support there is nothing between them.

Both are free to download. Clockwork sells 1 one-off in-app purchase. MR asks for nothing beyond the download.

Clockwork holds the better App Store score, 4.4 against 3.5. Both are backed by a comparable volume of ratings — 6 and 24 respectively. Written reviews complicate that: 55% of MR's written reviews are positive against 43% of Clockwork's, so the app with the better star average is not the one people write more warmly about.

MR ships an update every 3 months, Clockwork every 3 weeks. The most recent releases landed on September 20, 2026 and September 11, 2026 respectively.
