The interface looks clean and neat. When I tried out some of the various options I had little success. When I clicked on <TEXT> a text box opened which I could expand both down and across the page. I could type in it, but I had no luck in changing the fonts. When I used <DRAW> a box at the bottom of the screen popped up which allowed me to choose between a pen, pencil, marker and eraser. There was a color wheel to color the drawing instrument, but the choice did not save. The choice was indicated by a series of letters and numbers on the wheel so the only way to get back the same exact color seemed to be to record those symbols and put them in next time you wanted that color. When I started to draw the only way I could initiate a stroke was inside an existing text box. The stroke didn’t show until I was outside the box, but that meant that the drawing always started right at the bottom or side of the box. When I tried to erase there was no effect if I erased over what I had drawn. I tried starting inside the text box but that didn’t work either. At that point I admit I gave up. This app just didn’t work for me but using a 2020 16” MacBook Pro running OS 10.15.3. was within the requirements stated for the app. I tried contacting the seller with questions but after several days of waiting for a response to no avail I decided to write this review.
