Pic Collage was one of the first apps I downloaded on my iPad and I've been using it ever since.
Using the simple layout options, select the best one for your photos, and then add photos from your device or from the web. You can also add text and stickers, change the background, and create special effects for your photos.
Your creations can be saved to your device, instagram, twitter, facebook, or tumblr.
This app is an absolute must for students. It can be used in any subject area and can be as detailed as you want it to be.
