Hello, I used to use this app (Youtubetomp3) but it hasn't been updated since ios7. It works on some of my devices on 8.4, but not all (and doesn't seem to be consistent with how it works). Does anyone know of an alternative way to download from youtube, covert to mp3, directly on an iphone? Ios 8.4 currently. Something that either allows to be played from the app, or to be placed in the default music app, but can still be moved around into playlists and such. Thanks for any suggestions!
