This app is to edit picture distortion and it dose not do the job well/at all. If you are a pro photographer I would stick to something like Photoshop light room. Even though it might be easier to just edit your pictures on your phone, this app simply isnt capable of what it is meant to be used for. Not worth the money and that is saying something because it was only $3.00 I will stick with Photoshop and just deal with downloading the photo and then fixing the distortion. Hope this helps someone from wasting their money.
