These are the apps I have/use

Editing:
-PicsArt- you can use this for many things. You can edit pictures, photoshop, put texts, and many different things

-Spark Post- you can use Spark Post for many different things, but I only use it to crop photos XD but it can do a lot of different things

-Bazaart- this app, I use for my photoshopping, it's so easy to do, and I'll do a tutorial for it! This app you can also put a text on it, edit the photos and much more.

-Phonto- this app is the absolute best for fonts! I'll do a step by step for you guys. You pretty much look up a site, and you download any font.

Pictures/images:
-Pinterest- This is my absolute favorite place to get images for covers

-We Heart It- this is another app to get images, and yes it is very good, but I prefer Pinterest

So those are all the apps I use. I'll make a few tutorials using the editing apps, just to show y'all what it's like :)
