# Phazr vs Lab | Audio

Phazr's advantage is rating (4.6 vs 4.0) and ratings volume (137 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

Phazr holds the better App Store score, 4.6 against 4.0.

Written reviews complicate that: 82% of Phazr's written reviews are positive against 100% of Lab | Audio's, so the app with the better star average is not the one people write more warmly about.
