Ukrainische Sprache

Ich nutze die App regelmäßig und schätze ihre Qualität sehr.
Ich halte es für wichtig, die ukrainische Sprache als Übersetzungsoption hinzuzufügen. Das würde vielen Menschen helfen und die sprachliche Vielfalt der App sinnvoll erweitern.

Die Unterstützung der ukrainischen Sprache trägt außerdem dazu bei, die kulturelle Identität und den europäischen Austausch zu stärken.

Ich würde mich sehr über diese Erweiterung freuen. Vielen Dank!

Ad infested.

LEO was the “go to” German dictionary, but recent updates have made the app frequently unresponsive and laden will full screen, unskippable ads.

Not usable anymore

I’ve used it for years and was fine with the addition of ads, but they’ve reached a point where the app is no longer practical to use properly. I deleted it.

Werbung

Leo seit mindestens 15? Jahren benutzt, kein Problem mit statistischer Werbung, aber Fullscreen-Werbevideos sind einfach zu viel.

Ea war ne schöne Zeit. ChatGPT und Gemini sind eh besser.
