Verdict

The call

The clearest difference is review sentiment: OneClock at 83% against Flip Clock's 45%. Flip Clock's advantage is monetization model (free with in-app purchases vs subscription) and rating (4.4 vs 3.9). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. OneClock sells 2 in-app purchases, starting at $0.99 per month and Flip Clock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Flip Clock holds the better App Store score, 4.4 against 3.9. That said, the two scores are not equally well evidenced: Flip Clock has 353 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 83% of OneClock's written reviews are positive against 45% of Flip Clock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

OneClock ships an update every 3 months, Flip Clock monthly. Both last shipped on October 24, 2026.
