# Dotty vs Arm Simulator

The clearest difference is review sentiment: Dotty at 100% against Arm Simulator's 42%. Dotty also leads on ads (none vs shown) and rating (4.8 vs 4.6). Arm Simulator's advantage is ratings volume (36K vs 22). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Dotty 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.

Dotty holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Arm Simulator has 36K ratings behind it against 22, so its average is the more settled of the two. Written reviews point the same way: 100% of Dotty's written reviews are positive against 42% of Arm Simulator's.

Dotty ships an update every 6 days, Arm Simulator fortnightly. The most recent releases landed on September 21, 2026 and October 15, 2026 respectively.
