# WHEELTOP vs X

The clearest difference is rating: X at 4.1 against WHEELTOP's 2.1. X also leads on update cadence (weekly vs every 2 months). WHEELTOP's advantage is review sentiment (23% vs 0%). On price, ratings volume, ads and in-app purchases there is nothing between them.

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

X holds the better App Store score, 4.1 against 2.1. Both are backed by a comparable volume of ratings — 15 and 7 respectively. Written reviews complicate that: 23% of WHEELTOP's written reviews are positive against 0% of X's, so the app with the better star average is not the one people write more warmly about.

WHEELTOP ships an update every 2 months, X weekly. The most recent releases landed on September 26, 2026 and September 13, 2026 respectively.
