Verdict

The call

The clearest difference is price: OneClock at Free against Flip Clock Pro's $2.99. OneClock also leads on review sentiment (83% vs 74%). Flip Clock Pro's advantage is rating (4.6 vs 3.9) and in-app purchases (none vs 2). On update cadence, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Flip Clock Pro holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Flip Clock Pro has 1.5K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 74% of Flip Clock Pro's written reviews are positive against 83% of OneClock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flip Clock Pro ships an update every 2 months, OneClock every 3 months. The most recent releases landed on September 30, 2026 and September 26, 2026 respectively.
