Yes it says one star but i want to be the first one star. But there is nothing bad about the app, i like it. So I would recommend.

Best language learning app I’ve used by far. Better than Duolingo by a long shot!

The best part is that its free and has no ads.(AnkiMobile $25) Edit: Best app for a clean interface for learning Toki Pona with SRS!!! It uses a similar format to Anki but only has two buttons: hard and easy. I prefer Anki's customizability and I like the user-friendly format, but I didn't see any sentences and often other specialized apps would be better: The main iOS toki pona app, renshuu or lingodeer for japanese, etc... However minecraft enhantment table isa unique language I havent seen The description says you can learn anything, but the deck selection is very limited. Honestly has potential, but is still primitive. Disclaimer: I only used it for about 10 min and based my review off of that.
