# Clockwork vs Timegrapher

The clearest difference is rating: Clockwork at 4.4 against Timegrapher's 2.8. Clockwork also leads on update cadence (every 3 weeks vs every 8 months). Timegrapher's advantage is review sentiment (55% vs 43%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Clockwork sells 1 one-off in-app purchase and Timegrapher sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Clockwork holds the better App Store score, 4.4 against 2.8. Both are backed by a comparable volume of ratings — 24 and 44 respectively. Written reviews complicate that: 43% of Clockwork's written reviews are positive against 55% of Timegrapher's, so the app with the better star average is not the one people write more warmly about.

Clockwork ships an update every 3 weeks, Timegrapher every 8 months. The most recent releases landed on September 11, 2026 and September 25, 2026 respectively.
