# Scribble Rider vs Arm Simulator

The clearest difference is ratings volume: Scribble Rider at 302K against Arm Simulator's 36K. Arm Simulator's advantage is review sentiment (42% vs 31%) and update cadence (fortnightly vs monthly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Scribble Rider sells 1 one-off in-app purchase and Arm Simulator sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Scribble Rider against 4.6 for Arm Simulator. That said, the two scores are not equally well evidenced: Scribble Rider has 302K ratings behind it against 36K, so its average is the more settled of the two. Written reviews are what separate them: 31% of Scribble Rider's written reviews are positive against 42% of Arm Simulator's.

Scribble Rider ships an update monthly, Arm Simulator fortnightly. Both last shipped on October 17, 2026.
