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.

Hi Lin – thank you so much for your feedback. The launch bug has been fixed, sorry about that. Let me know if you have further feedback @ optimem.org/discord

They got rid of the constant vibration, but now there's no way to turn off the double ding or double tapping EVERY SINGLE TIME you respond! WHY? Why does there have to be noise, or vibration? And you have to turn sound ON, in order to activate all the toggles to turn the sounds OFF 🤯😤 Why??? Dim, or disable, or hide all the sound toggles if they can't be used. Don't let the user tap, and tap, and tap, and wonder why they aren't responding! 🤮

Hey Andrew, sorry about that. It looks like you're on an older version of the app which had aggressive vibration and a bug with the toggle. Updating will fix both. Optimem is a free, solo developer project – if you have more feedback reach out at https://optimem.org/discord and I'll take a look.

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!

Hey MrGatlampa – thank you for your feedback. I have some good news – these issues are now fixed in the latest version! The app no longer freezes on launch, notifications are sent properly, and lag is fixed! Some cards are bi-directional – this is intended, but can be disabled
