# Global Time Machine vs Chrono

The clearest difference is update cadence: Global Time Machine at every 2 weeks against Chrono's every 8 months. Global Time Machine also leads on review sentiment (58% vs 38%). Chrono's advantage is rating (4.0 vs 3.7) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Chrono holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 7 and 8 respectively. Written reviews complicate that: 58% of Global Time Machine's written reviews are positive against 38% of Chrono's, so the app with the better star average is not the one people write more warmly about.

Global Time Machine ships an update every 2 weeks, Chrono every 8 months. The most recent releases landed on October 16, 2026 and October 17, 2026 respectively.
