A very highly recommended application for photo editing on iOS. I find this very useful when I need to do posts on my WordPress blog using the WordPress application for iOS. You need to make sure that the images you upload on your website is optimised for web pages so that the pages load fast. If you take a picture from your iPhone and post it directly to your webpage, then that would take a lot of time to load the page.
I change the size of the picture and also there are some presets which is use to make my images vibrant before posting it.
