Both are free to download. Chai.X sells 9 in-app purchases, starting at $6.99 per 7 days and Sonder sells 9 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Chai.X holds the better App Store score, 4.2 against 2.4. Both are backed by a comparable volume of ratings — 11 and 5 respectively. Written reviews complicate that: 0% of Chai.X's written reviews are positive against 33% of Sonder's, so the app with the better star average is not the one people write more warmly about.
