This app is very cool

I have a lot of fun with this app! It would be great for tablets where precision is much more available due to size for quick business mock ups or something of that manner. I can see this being a great tool for on the go advertisements. I mainly use it for the fun factor!! Once I learned the basics, the rest came easy! Haven't gotten a mug or a phone case done yet, so I can't comment much on quality there. I like this app though. It works really well for my needs, anyway. 👍🏻

Saving strikers in the Dash board issue

I was subscribed for Knockout HD plus sense few months for 1 year but right my account shows that I’m regular accountant and I cannot access my uploaded stickers I’m getting messages saying that I can only access 5 pictures and if need to access more of my pictures I should subscribe again on time that I’m already subscribed until June 2021 as showing in Apple subscriptions.
Would you please review my account and resolve this issue ASAP and please contact me soon for any additional information.
Note: I did not find any contact information for your company in the app reviews or in your applications!!!?

Only one I found for the job

I wanted to cut a shape (person, face, ball etc) out of an existing picture from my phone and superimpose it on another picture from my phone and be able to resize while doing it so that I could scale it to the look right in the new picture. Can't say much else other than it does what I have just described. I'm docking them a star for the annoying pop up dialog boxes, the most annoying of which is the one that kept asking me to do this review in order to unlock additional features (which I don't want). Just wanted to dialog box to quit appearing.
