# Thesys vs ULang

The clearest difference is rating: Thesys at 4.7 against ULang's 3.8. Thesys also leads on ratings volume (85 vs 4). ULang's advantage is in-app purchases (none vs 1) and review sentiment (71% vs 59%). On price, ads and device support there is nothing between them.

Both are free to download. Thesys sells 1 one-off in-app purchase. ULang asks for nothing beyond the download.

Thesys holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Thesys has 85 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 59% of Thesys's written reviews are positive against 71% of ULang's, so the app with the better star average is not the one people write more warmly about.
