The automatic edge detecting can be improved but overall great app for collectors. Saves me a lot of time

I appreciate the availability of a free app, but not when it doesn’t even work to begin with i.e. uploading scans. Have tried doing so multiple times now, but nothing happens other than the spinning circle telling me to wait. Please fix this and honestly, if it works well, then charge a one time fee of say, $5 - you SHOULD be compensated for your work - assuming it works!

App is very easy to use. Some cards took a few tries to scan, but I appreciate being able to scan and save cards for free.

I was looking for an app to help me pre-grade my cards before sending them to PSA. This app helped me visualize the subtle centering differences! Way easier than using calipers
