The developer of this app deliberately pushed an update of his previous app to break the functionality so that to force users buy his new app. Check Google Play reviews. I lost my few of my notes.

As a former Epistle user, I wouldn't buy this app. The developer has demonstrated a willingness to drop support for his own products, so why trust him to maintain Draft?

Yes, but it's also in many ways inferior to Epistle - the previous major note-taking app on Android, which was unfortunately taken down sometime this year by the same guy that made this app, without any explanations save for a few "what did you expect?" replies to comments on Google Play.

I also vote for Tag&Rename. It's the Cadillac of ID3 tag managers. Not freeware, so that is a consideration, but worth it for me.
