# F vs Zen AutoPan

The clearest difference is price: Zen AutoPan at Free against F's $2.99. F's advantage is rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.0). On review sentiment, ratings volume, update cadence and ads there is nothing between them.

F holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 18 and 15 respectively. Written reviews complicate that: 78% of F's written reviews are positive against 80% of Zen AutoPan's, so the app with the better star average is not the one people write more warmly about.
