# Shootility SightSet vs AB Quantum

AB Quantum holds the better App Store score, 4.7 against 3.5.

Written reviews complicate that: 74% of Shootility SightSet's written reviews are positive against 45% of AB Quantum's, so the app with the better star average is not the one people write more warmly about.
