good and easy to use apps I use to make minimal / simple / semi manip covers are

ALL FREEEE

▶ Picsart ; you can do pretty much anything to be honest. I highly recommend you to use this app.

▶ Phonto ; a great app that has many fonts and it is easiest to download fonts to this app since PicsArt has only a few decent fonts that are free. also, even I don't really know how to download fonts on PicsArt haha

▶ Canva ; only available on computer or iPad but is free. great to make minimal covers and graphics. has beautiful templates for many things such as covers, album covers, or even a document or ppt

hope this helped. please comment on what you you want to know next :3
