What you get
• Browse 17,000+ marks four ways: by date letter, by object, by animal, or by shape. Whichever lane matches the punch in front
of you.
• Date-letter lookup for London, Birmingham, Sheffield, Edinburgh, Chester, Dublin, and Glasgow. Pin the exact year a piece left
the assay office.
• Maker's marks and assay punches show town, working years, and metal standard at a glance. Useful when you're trying to tell a
Hester Bateman from a 1920s revival.
• Save favourites and pull them up fast on the next estate-sale visit. The marks you check often stay one tap away.
• Second opinion reader: point your camera at a punch and get a candidate match drawn from the catalogue. Use it as a shortlist,
then confirm against the full record.
• Plain-English glossary of trade terms. Assay, duty mark, lion passant, sterling, britannia, town mark, date letter. Newcomers
can follow what dealers are saying.

I used this app, then had to cancel last year because of a hiccup - I was paying the subscription, but all of a sudden I didn’t have full access. Fast forward, thought I would give it another go. I absolutely love this app. One of the best resources without having to search multiple websites. Does it have quirks, maybe - but I love using this as a reference. Keep doing what you are doing!
Liar and a cheat
MistaCloudStrife
Back in 2022 I purchased the full unlock for this app, allowing me to view all of the marks without restriction. According to my in-app purchase history “full unlock” was purchased March 24, 2022 for $4.99. I don’t use this app often, but it has been helpful every once in a while. I logged in today, and when I try to search for a mark, the app now tries to charge me for a SUBSCRIPTION FEE to unlock what I ALREADY PAID FOR. There is an option to restore purchase. This does nothing. Their button to contact support does not work as well. Whoever made this app is a liar and a cheat. If you are doing this, please refund the full unlock I previously paid for, because I obviously do not have a “full unlock” at all.
I wish they updated
Gertydude
Great app, more resources than you’ll find in other places (websites, most singular books). However, I wish they’d update their catalog. The search functionality is great once I figured out I had to uninstall and reinstall for it to not crash. Modern marks would be great to include!
CANT GET RID OF IT
Lesbee123
I have tried to delete this app, but it does not show up anywhere in my iPhone listing of current apps, nor in any deep search of the phone itself… Apparently I have simply signed up for a dollar a week and now cannot turn it off. I have contacted the website twice now asking for instructions on how to turn it off and quit paying for it, but to no avail. Additionally, the button at the end of the FAQ section where you can get help doesn’t work, so I can’t get help that way. Best of luck. Bad!If I could give it less than 1 star I would.
Now with a 7-day free trial on the monthly plan. Lifetime access is $39.99. Clearer messages when a purchase needs your attention.
