# Sand Timer vs Matrix Clocca

The clearest difference is review sentiment: Matrix Clocca at 50% against Sand Timer's 6%. Matrix Clocca also leads on ads (none vs shown) and update cadence (weekly vs every 8 months). Sand Timer's advantage is rating (3.8 vs 2.3) and ratings volume (150 vs 3). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Sand Timer sells 4 in-app purchases, starting at $0.99 per 7 days and Matrix Clocca sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sand Timer holds the better App Store score, 3.8 against 2.3. That said, the two scores are not equally well evidenced: Sand Timer has 150 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 6% of Sand Timer's written reviews are positive against 50% of Matrix Clocca's, so the app with the better star average is not the one people write more warmly about.

Sand Timer ships an update every 8 months, Matrix Clocca weekly. The most recent releases landed on October 19, 2026 and October 11, 2026 respectively.
