Default app for all file types?

It was good for calculate hash.
HOWEVER, It keep setting itself as the default app for almost all file types, when u open an .rar, it came out instead of your unarchive app, when u open a mkv file, it came out instead of ur favourite player.
Also it sometimes pop ADs about author’s other apps.
Please keep it simple and focus what it should be!
