<p>I can recommend the Snapseed app. It's an easy to use app available for IOS and android with which you can edit you photos after you took them and improve their quality. You can either choose for a preset editing mode or change almost everything manually from the level of brightness, contrast, sharpness and so on. These are the ways you can improve your quality to your photos, but there are many other options also as adding filters, blurring certain parts of a photo and healing. Feel free to check it out.&nbsp;</p>
