# MARS vs Ride On Flex

The clearest difference is rating: Ride On Flex at 4.7 against MARS's 4.2. MARS's advantage is review sentiment (80% vs 64%) and monetization model (free vs ad-supported). On price, ratings volume, update cadence and ads there is nothing between them.

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

Ride On Flex holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 24 and 57 respectively. Written reviews complicate that: 80% of MARS's written reviews are positive against 64% of Ride On Flex's, so the app with the better star average is not the one people write more warmly about.

MARS ships an update monthly, Ride On Flex every 5 weeks. The most recent releases landed on September 19, 2026 and October 12, 2026 respectively.
