It's very good and easy to use - it gets me to the correct stamp in the vast majority of cases. It's worth subscribing to the pro version, but it's just unfortunate that the subscription doesn't cover all of their suite of Android apps. And it would be nice if the info listing pages included Scott catalog numbers. But overall, the stamp identifier is highly recommended. It would also be great if the Android app were made compatible with Chromebooks.

Thank you for your feedback, Dave. The app is about recognition and more info about the stamp found can be seen when tapping "See on Colnect". If you believe the recognition works great, we'd appreciate your support with a 5* review :)

Pretty stream line, easy to use, occasionally I'll hit a stamp they don't have yet but they're getting there. It has a favorites option for saving stamps of interest. I could see them growing this feature in the future, it may become a good way to keep track of what you have (and need) in the future.

It hasn't identified a single stamp I have. Update ...would Like to note the arrogant condescending tone of the app designers reply. I would also like the developer to know that I've been a professional photographer for 25 years and I'm more than capable of taking an accurate photographs of a stamp and following simple directions. I have never once in my life left a bad review at the app store. The app simply sucks. The suggested matches were not even remotely close.

Our app has greatly improved since this review was written and we kindly ask you to give it another spin. When cropping all background in an okay quality image, we'll identify almost all stamps you'll throw our way. We also offer human support by clicking "Can't find your stamp?" directly from the app. Hoping for 5 stars now :)
