Keeps crashing on me – Sketchar: AR Drawing App Review

I can’t even get my four crosses on the paper an it shuts down the app on me. I hope I don’t have to delete this app an try another one, I’d like to give it five stars but gave it three because it’s a great concept. First though.....”Disappointed”. Using this app on a iPhone 7plus.
