Neat Idea. Very clean. I’d love the ability to make the Navigation Bar a darker color. A share sheet would be nice, too. I do notice a bug with the keyboard; when it collapses, it leaves some white padding on the bottom on my iPhone X. Otherwise, good start. I’ll be looking forward to the updates!
Sorry for the late reply. I am aware of the keyboard issue. It's a bug in iOS 11 and its already reported to apple (bug : 34229664). you can access the share screen by clicking on the 3 dots at the bottom.
