Verdict

The call

The clearest difference is review sentiment: sofatutor at 81% against Klett Lernen's 25%. sofatutor also leads on ratings volume (138 vs 1) and update cadence (monthly vs every 2 months). Klett Lernen's advantage is rating (5.0 vs 4.2) and in-app purchases (none vs 5). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Klett Lernen holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: sofatutor has 138 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of sofatutor's written reviews are positive against 25% of Klett Lernen's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

sofatutor ships an update monthly, Klett Lernen every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
