Hello Hunters!
This is me with an app I built the last month in my free time. It is very easy to use, just swipe right the words you want to save and swipe left the ones you want to discard.
For the people who are interested in how I made it:
I coded it using React Native and MongoDB for databases and designed it using Sketch.
That's it! If you have questions, I'll be open to answer 😊. Just let me know in a comment.
