# Timegrapher X vs Clockwork

The clearest difference is price: Clockwork at Free against Timegrapher X's $29.99. Clockwork also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (16.4 vs 18.0). Timegrapher X's advantage is review sentiment (70% vs 43%). On rating, ratings volume, ads and in-app purchases there is nothing between them.

Clockwork is free to download; Timegrapher X costs $29.99 up front. Timegrapher X sells 1 one-off in-app purchase and Clockwork 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 4.2. Both are backed by a comparable volume of ratings — 23 and 24 respectively. Written reviews complicate that: 70% of Timegrapher X'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.

Timegrapher X ships an update every 2 months, Clockwork every 3 weeks. The most recent releases landed on October 22, 2026 and October 19, 2026 respectively.
