UI

Many of the flash cards aren’t showing any description when the pop up, they are glitched.

We’re sorry for the trouble. Please email support@cognifly.net with the deck name and a screenshot of an affected card so we can investigate and help.

Response from developer

Congratulations on passing your French test! 🎉 We’re so glad Cogni helped.

Useful but has annoying bugs

I like this app because I can easily make study material with the flash cards, however I’m giving it 3 stars because at random the cursor will move to the end of a paragraph while I’m trying to correct information AND at random it deletes a letter that I just typed. Other times it completely deletes a paragraph that I’m currently working on. Please fix.

Thank you for reporting this, and we’re sorry for the trouble. Please email support@cognifly.net with your device model, system version and, if possible, a short screen recording without personal information. This will help us investigate.

Change of order

It used to be that the card was in English and the hidden one was in the new language, since the last new update this changed. The experience is horrible.
