Android App Improvements
I know you just develop the android app and it´s a really helpful tool. But I think you should consider adding the vocabulary function to it, I think reviewing the vocabulary would be great. Thanks.
I have problems with the "practice mode" in the android app. Every time I practice I get my points, but it doesn't update the "word strength" on the website. Therefore I am always getting the same words over and over again although on the website the "practice mode" is working fine.
