swipelist: clear your playlist

I downloaded the app and purchased the $5 "premium" lifetime subscription to unlock all the features but the application is way too buggy to use. I can't swipe more than 20 songs without my screen going blank and having to re-start the process. At this point, the app has too many issue to even be considered functional. I give it 2 stars instead of 0 because I like the concept, and the layout is decently-designed but the app itself is poorly made. I wouldn't recommend this to anyone in its current state. I hope it gets further updates and eventually becomes something that's actually usable, but like I said, at this point, this app is garbage. Congratulations to the develops for swindling $5 dollars from me. I hope this review prevents anyone else from wasting their time, downloading the app, and spending their money.

For very big playlist after about 300 songs it will go blank and make you start from 1 again and does not save your spot and then will do it again any fix?
