Great app, it's been super useful and the pre-made packs I've tried are excellent. Seems like everything in this app is accessible for free, I haven't found any paid features. Thank you! Only issue is that I have to start the app twice every time I want to use it. The first time I open it, none of the buttons work and I can't select anything or scroll. Works perfectly on the second try every time, so not a big deal, just annoying. Otherwise, it's been perfect for achieving my goals.

Great app! Will donate when I'm not broke. Only complaint is inability to manually order the deck list since the order changes any time you update any of the decks, tho it doesn't seem to happen until you fully close and restart the app. Would love to see decks for the shavian alphabet and the IPA, including sound with an example word. "Puh as in peep" and "Duh as in deep" for example. Shavian is an alternate alphabet optimized for the English language.

The app is very nice for memorizing stuff, however it does have problems. It sometimes doesn't launch correctly, notifications are only sent once you open the app, making the reminders useless. Some features are confusing and not explained. Scrolling through a list of words somehow lags insanely much?? I'm not sute bit I think that the same items behave as if they are listed twice as two seperate items, one from language1 -> language 2, and one from language2 -> language1. Fix to make app great!
