This app is fun, and well worth $3. Theres a bit of a learning curve and it requires a steady hand, but with a little care and practice, you can really do some amazing things! PS I was able to use my Apple Pencil with my iPad Pro and this made tracing around the edges of the image you wish to add to another picture SO MUCH EASIER!
