Adobe Photoshop Express

Adobe Photoshop Express is a mobile version of Adobe Photoshop, and it is completely free. It allows you to fix up or edit a picture you took on your mobile device with out having to transfer it to a computer. You can then upload it straight to your favorite social media platform. This is an awesome app and I highly recommend it and the best part is that its completely free.
