Genius. It works with a little practice. I like how the ads are structured in the app. You earn points that you can use to have an ad-free experience. So I just watch ads in bulk to earn the points. It's like playing a small game before making art. It's still great, especially if it's free. We starving artists sometimes don't have the $$ to splurge on the other paid apps.

Works great. I worked as a graphic designer in the 80s and 90s. We had a optical contraption the projected an image on your drawing board. This works similar by overlaying a transparent picture to your cameras field of view. You have to watch an ad before using it. Big deal. If I were to use it professionally for hours on end I would want an ad free version. But for the occasional use it's perfect. I really like the opacity slide to adjust transparency. Great to get a sketch on paper.

Developer is prompt when reporting an issue. Using this app on phone to trace is great. Unfortunately, the problem keeps coming back I cannot go past the introduction and instructions, inspite of giving access to camera. There is no settings options within the app to fix the issue.
