"title": "Strange",
"body": "I love this app. It has identified every stamp that I scan so far. The only problem I have is whenever I add a stamp to my collection the App Store opens up and brings me to the page to download the app again. Is that a known issue, or is that what’s supposed to happen because it’s really annoying. It happens after every single stamp I add to the collection.",

{
"rating": 2,
"title": "AI adds no value",
"body": "Stampnote identifier is visually pleasing with intuitive use. It’s point, click, select. However it only identifies the correct stamp about 75% of the time. The cropping feature allows you to try-again, but the results are usually the same. The AI is useless. It merely describes the stamp pictured (blue stamp with eagle design and a 25c denomination) which the user has already done by merely looking at the stamp. It does not state the print run (number printed), the designer/printer, watermarks, variants, or perforations. When correctly identified it has been an accurate catalog number. And the valuations vary wildly. One stamp today had a value range of $4-$1500. Not certain how the app establishes value, but it appears to be fluff. So, enjoy the free version, CONFIRM the accuracy, and be skeptical of the cash valuations. But do not rely exclusively on the apps findings.",

"title": "Works nicely",
"body": "It identifies all the loose stamps I had in my collection, but I can’t sort them by date or denomination, only country. Plus it asks if you are selling, etc but no where does it show you where it is selling them or where and how to list them. Plus now I need to screen shot any or all of them to list them externally. So needless to say, don’t think the $40 price tag is worth it. Just my opinion.",

"title": "Well",
"body": "I was only able to check/evaluate two stamps before the app refused to go any further without purchase. I get it, also It seems like a solid app, however as far as being “free” or even the first one to show up when using search phrase “free app for _____” …. Look elsewhere if you want “free to use“. Peace to my peeps.",

"title": "Bugs that need fixing",
"body": "The app is really perfection with the stamp information it provides. However the app does not allow you to create a “collection” from the “history” of stamps you have already photographed. You can’t go back and organize photos of your stamps into collections. You must create a collection for that stamp at the time you first photograph it. And, there is no “Help” feature. Thank you.",
