# RetroClock vs Flip Clock 3D

The clearest difference is review sentiment: Flip Clock 3D at 100% against RetroClock's 50%. Flip Clock 3D also leads on update cadence (weekly vs every 3 weeks) and ratings volume (24 vs 3). RetroClock's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. RetroClock sells 1 one-off in-app purchase and Flip Clock 3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

RetroClock holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Flip Clock 3D has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of RetroClock's written reviews are positive against 100% of Flip Clock 3D's, so the app with the better star average is not the one people write more warmly about.

RetroClock ships an update every 3 weeks, Flip Clock 3D weekly. Both last shipped on September 24, 2026.
