# RapZap chess clock vs Chess Timer

The clearest difference is rating: Chess Timer at 4.2 against RapZap chess clock's 3.2. Chess Timer also leads on ratings volume (37 vs 6). RapZap chess clock's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (33% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. RapZap chess clock sells 2 one-off in-app purchases and Chess Timer sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chess Timer holds the better App Store score, 4.2 against 3.2. That said, the two scores are not equally well evidenced: Chess Timer has 37 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 33% of RapZap chess clock's written reviews are positive against 0% of Chess Timer's, so the app with the better star average is not the one people write more warmly about.

RapZap chess clock ships an update fortnightly, Chess Timer monthly. The most recent releases landed on June 6, 2026 and September 21, 2026 respectively.
