Comments on Karteto: Vocab Builder for Android

★★★★★ Ionut Copoiu · Jan 12, 2024
A hidden gem! I see that there are basically no reviews - time to write one! It's a pretty great app to learn any language. Give it a try! Looks like they are pretty new, but for me this has been the best flashcard app!
★★★★★ Mirela Rus · Jan 12, 2024
Fun, easy way to learn a new language, happy to see Croatian included, not many languages learning apps have it!
★★★★★ Yuin Onn Mak · Jan 6, 2026
Hello! Just subscribed for 1 year! I really believe in this app because it reminded me of how I learned Chinese when I was young. Now, this is helping me learn Japanese. Great app so far but I have a little feedback. For the Japanese Kanji, it would be nice if you included the Romaji with it as well. Would be helpful for latin character readers. Thank you for your attention to this matter!
★★★★★ Alexander Tolstyakov · Jun 19, 2023
Flashcards are done greatly with good and flexible settings options. Very good for growing vocabulary. The app has a few bugs at the moment, but it's a very early release that is going to be fixed and get better.
★★☆☆☆ Denis Yakovlev · Jan 8, 2026
In general app smooth and good-looking. But the price of the product from the beginning is too overpriced for unknown app. 1) I can't delete my app manually. And yes, I want to do it. 2) I can't change the "my default language". 3) And the education process are really pure. Really, I added new unknown words for me, and they want me to translate and type the words that was added recently. How It's really possible? 4) "Free" possibilities are super small.
★★☆☆☆ Nathan Emanuel · Jan 4, 2026
The idea is nice and the selection of words is good, but this is too much money for AI translations. Also, the app does not feel finished yet.
★☆☆☆☆ Matan · Sep 20, 2025
I wasn't able to sign up - I always get to the "Let's start!" screen but clicking it doesn't continue, and choosing "I already have an account" and choosing a Google account gets you back to the same screen.
