# Clockwork vs Precision Watch

Clockwork and Precision Watch both sit at 4.4 stars, but that hides the real split: 100% of Precision Watch's written reviews are positive against 43% of Clockwork's. Precision Watch also leads on device support (3 vs 1). Clockwork's advantage is ads (none vs shown) and ratings volume (24 vs 2). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Clockwork sells 1 one-off in-app purchase and Precision Watch sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for Clockwork against 4.5 for Precision Watch. That said, the two scores are not equally well evidenced: Clockwork has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 43% of Clockwork's written reviews are positive against 100% of Precision Watch's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 11, 2026 and July 18, 2026 respectively.
