Accurately Grade and Measure Stamp Perforations

The Stamp Analyser digitally measures the stamp perforations, the stamp frame and the balance among the four margins to determine the preliminary centering grade of the stamp. You no longer need a perforation gauge or reliance on the seller’s definition of stamp centering. The Stamp Analyser provides this information based on accurate measurement; no more guesswork. All you need to do is to provide a good scan or a good photograph of the stamp and the Stamp Analyser does the rest.

Optionally, you can add the stamp Soundness and Eye Appeal components to obtain the final grade. The Soundness and Eye Appeal components are based on the PSE Grading Guide.

The Stamp Analyser user interface has been designed to be intuitive and simple. On the Mac, you simply drag and drop your stamp image into the Stamp Analyser. On the iPad and iPhone, you can either take a photo of the stamp or select it from the photo library.

IOS 10 or higher required for version 9.

Struggle to success


I assumed I would be able to simply photograph my stamps and get a fast read on the perforations. It does work with photographing, provided you get the QR symbol from the developer web site which I missed on the first go-around. The app developer was most kind and stayed with me through success. To get the accuracy I desired it is essential to scan the stamps, not simply photograph them. Obviously, dpi setting on the scanner must coincide with the app dpi setting. This should occur automatically of you have scanned properly. Because you have to know how to use your scanner and its related software, and if you are a novice like me, be prepared to invest a few hours fiddling around with it before you can reliably use the scans with the app. With that done, the app performs great. Rashid, the developer, takes customer support to a new level. Thanks Rashid

I just purchased the Stamp Analyser software from Rakium, Inc. I had inherited my Dad's stamp collection and realized after just a little research that being able to accurately measure the perforations of stamps would be critical to knowing which specific stamp I was looking at. I ordered a perforation gauge but grew frustrated right away with no confidence in my results. Researching the internet for software that could eliminate the frustration and add confidence in the measurement, I came across a few options. I chose the Stamp Analyser because of its superior ease of use with Apple products. Getting started as a newbie to philately and not too tech savvy, I had some questions about how I would be using the software. I wrote to the email address offered for support and heard back in short order . All my questions were answered thoroughly and I am a fan!!!! Would recommend to all collectors. And most users will will be up and running after just a brief reading of the details on the website. Excellent functionality with just a scanner and an Ipad or or your IPhone or use your Mac...

Lousy & Limited


Great idea but poorly functioning. While I'm all for simplicity, $30 seems steep for something so limited. It's main function is to grade stamps by analyzing a photo or scan of a stamp. Unfortunately after several photos, it finally kind of got it close. It allows you to move the orange bars but not the blue...which is problematic. Even with scanned images or images taken with a good camera are analyses poorly.

Cool idea, but it rarely gets it right. Hopefully the desktop/computer version of this does a better job. Will be seeking a refund.
