# Time Master vs Dynamic Calendar

The clearest difference is rating: Dynamic Calendar at 4.2 against Time Master's 2.3. Time Master's advantage is in-app purchases (none vs 1) and update cadence (weekly vs every 3 weeks). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. Dynamic Calendar sells 1 one-off in-app purchase. Time Master asks for nothing beyond the download.

Dynamic Calendar holds the better App Store score, 4.2 against 2.3. Both are backed by a comparable volume of ratings — 3 and 6 respectively. Written reviews complicate that: 33% of Time Master's written reviews are positive against 23% of Dynamic Calendar's, so the app with the better star average is not the one people write more warmly about.

Time Master ships an update weekly, Dynamic Calendar every 3 weeks. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
