# S1Fun vs Off Day

The clearest difference is in-app purchases: Off Day at none against S1Fun's 4. Off Day also leads on ratings volume (33 vs 1) and update cadence (fortnightly vs monthly). S1Fun's advantage is iOS requirement (12.0 vs 16.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. S1Fun sells 4 one-off in-app purchases. Off Day asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for S1Fun against 5.0 for Off Day. That said, the two scores are not equally well evidenced: Off Day has 33 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 100% of S1Fun's written reviews are positive against 95% of Off Day's.

S1Fun ships an update monthly, Off Day fortnightly. Both last shipped on October 24, 2026.
