# Uvol vs Chai.X

The clearest difference is review sentiment: Uvol at 90% against Chai.X's 0%. Chai.X's advantage is rating (4.1 vs 3.2) and chart position (#208 vs unranked). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Uvol sells 10 in-app purchases, starting at $4.99 per 7 days and Chai.X sells 9 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chai.X holds the better App Store score, 4.1 against 3.2. Both are backed by a comparable volume of ratings — 18 and 15 respectively. Written reviews complicate that: 90% of Uvol's written reviews are positive against 0% of Chai.X's, so the app with the better star average is not the one people write more warmly about.

Uvol ships an update weekly, Chai.X every 2 weeks. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
