It's still quite limited. I lowered my rating because of it. I wish it would get updated to become a more study-friendly app. There are no Smart Study and Progressive Study options as in iOS. I really appreciate them as I can study all subjects at once. As soon as they are added, I'll give it a much higher rating. I rarely use it because of what it lacks right now. I guess we'll see if anything changes for the better.
Cards are saved server side, so if server is slow or you don't have a decent internet connection you can't access your cards -> Dev responded, I was wrong! 4 stars for now, will probably updated to 5 stars once I use it some more.
I paid full price for learning French and Spanish. They have great content, nice lessons with audio. Unfortunately, their algorithm to review cards is terrible. It takes hours to review a deck because it constantly repeats a few cards (regardless of whether you've rated the card as something you recall.) If they added the ability to stop repeating a card within one study session that would be amazing. I think they stopped developing the Android version though, the iOS version has more features. Too bad, I wish their cards could just be ported to Anki.
The back button now works. Glad the developer fixed that. However, after the update I am experiencing the frame rate lag issue. Inside the app the frame rate stutters/lags whenever I click anything. If the developer fixes this issue too; I will give 5 stars.
App deleted all of my self made cards. Now it is frozen and I cant even create or download new decks. Very limited creation abilities on phones, did not try the computer version.
It's a promising project, but the functionality is not fine tuned which makes it not very useful. There is a lot of good content and the app looks neat. But the repetition algorithm shows the "low-confidence" cards way too often, several times in one session , which is annoying. Also, the Android version is not as advanced as iOS and cannot train several decks together. With 500 cards per deck limitations, it sucks. I tried to purchase premium but there was an error. The support staff is helpful though.
