The online photo editing app I used was BeFunky. It includes settings like graphics, texts, textures, and overlay. They also have a huge range of filters to choose from. The text includes many different fonts to go with your theme. There is also, brightness, contrast, highlights, and shadows which you can control. I like this app because you can control how much you put a certain setting. Secondly, there is a lot of filters to choose from. https://www.befunky.com/ These are some of the pictures I edited on BeFunky.
