# eFlow vs mySigen

mySigen holds the better App Store score, 3.8 against 1.0. That said, the two scores are not equally well evidenced: mySigen has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of eFlow's written reviews are positive against 45% of mySigen's, so the app with the better star average is not the one people write more warmly about.
