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.

We have a new version! Our recognition algorithm was further improved. Please use our 'Not found?' feature in case the app still didn't manage to process your picture.

Update: I was being dumb. Tablet I was using didn't have flash function. App is awesome. Found an option I would like to see: on the picture crop screen, it would be nice to have an option to retake the picture without having to back up to app home screen first. I see how to reset the crop, but not retake photo. EDIT UPDATE: Would really love an option to connect to a wireless camera to take the pictures. I have muscle shakes so I have to have a brace/stand to get nonblurry pictures

Hi Christopher, thanks for the nice review :) We don't plan on adding extra camera functionality as we rely on what a device has but you may use ANY camera and then copy the pictures to your device and there either use our app or a browser by visiting https://colnect.com/en/stamps/identify

Could not identify any of my rare vintage. stamps. It was 0 out of 19. Not a single one. Google images literally did far better, identifying 11 out of the same 19 with another 3 being the wrong type. Being fair, this app did do very well identifying common issues past the 1930's to present. I ran 35 random common issues from 1932 to present and it was able to accurately identify 29 of the 35 with another 4 being the wrong type, but the right catagory.
