Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
