Great app!

If youre trying to identify the nuances of the US stamps, this is fantastic! You pick the stamp you want to ID, then it takes you detial by detial until you aerive at the right scott #. At the end it sums it all up with print type, perf, color, watermark, secret mark, etc. Its amazing for distinguishing similar appearing stamps. Easy to use too! I cant imagine why anyone would rate this any lower than 5 stars!

80% of the time it’s wrong.

This app stinks and I sunk $30 for something that doesn’t work. I want my money back.

bad app

notify apple to stop payment very disappointing

Don’t Bother

This app is useless.

Nothing works in this app

This is really an awful app It does not link correctly to the camera and so close up photos are difficult. The app makes it almost impossible to cancel the free subscription and basically says “ask apple” with a web address that is not hyperlinked I was so disappointed just having using what i thought was a similar app for coins which works great Do not purchase this program!
