# ATSim vs Comms

The clearest difference is in-app purchases: ATSim at none against Comms's 12. ATSim also leads on review sentiment (63% vs 36%) and iOS requirement (12.1 vs 15.1). Comms's advantage is ratings volume (207 vs 15). On price, rating, ads and device support there is nothing between them.

Both are free to download. Comms sells 10 in-app purchases, starting at $6.99 per 7 days. ATSim asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.1 for ATSim against 4.2 for Comms. That said, the two scores are not equally well evidenced: Comms has 207 ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 63% of ATSim's written reviews are positive against 36% of Comms's.
