My experience with this app is just frustrating. Beware if you're going to use it on phone while editing pdf file. Keyboard keeps on hiding when you tap a blank space or table, Non-sense space restrictions, cropping image is bad at least functions for some time, unable to drag photo to the desired location. Stubborn lines and spaces, thus, making you stop and create another line on a different space. This app is not really optimised for mobile. Tried on other phone, still disappointing results.
