# ConnectMySoftener vs A2O

The clearest difference is rating: A2O at 2.0 against ConnectMySoftener's 1.0. ConnectMySoftener's advantage is review sentiment (29% vs 0%) and update cadence (every 4 months vs every 11 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

A2O holds the better App Store score, 2.0 against 1.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 29% of ConnectMySoftener's written reviews are positive against 0% of A2O's, so the app with the better star average is not the one people write more warmly about.
