Verdict
The clearest difference is rating: Klett Lernen at 5.0 against Untis Mobile's 4.5. Untis Mobile's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (1.7K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Klett Lernen holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Untis Mobile has 1.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Untis Mobile'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.
Untis Mobile ships an update every 2 weeks, Klett Lernen every 2 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
