OutOfDark: Coin Catalog

A coin collection drifts apart easily. Some of it in a spreadsheet, some photographed on your phone, some only in your head. Then comes the question with no quick answer: what do I actually own, and what is it worth today?

OutOfDark is a personal catalog for your coin collection. Photograph the obverse and reverse, or paste an auction link. The app suggests the identification, pre-fills the details and creates an editable record. You review the result and get back to collecting.

WHAT THE APP DOES

- Photograph the obverse and reverse; recognition fills in country, year, metal, mint and denomination.
- Paste a link from an auction site and the entry is created, photos and listing price included.
- Upload an existing spreadsheet and create the whole collection at once.
- Organize the collection into categories, filter, search, edit several coins at once.
- Keep a value with every coin and watch how the collection develops over time.
- For bullion coins you can switch on value recalculation from the metal price.
- Keep your own notes, storage location and purchase records with each coin.
- Export the collection to a spreadsheet, with or without the financial columns.
- Protect the account with two-factor sign-in; data is backed up daily, encrypted.
- Set up Legacy and the collection summary is handed to someone close to you if the worst happens.
- Sell a coin on the marketplace, or offer it directly to other collectors.
- Ask the built-in assistant anything about numismatics.

WHO IT IS FOR

For a collector who takes the collection seriously but does not want to spend ten minutes typing in details for every coin. No complicated setup. Open the app with a coin in hand and moments later you have an editable record in the catalog.

GETTING STARTED

Try OutOfDark free for 14 days, no card required. After signing up you get a sample collection so you can see straight away how it looks with real data.

We built the app because we needed a catalog like this ourselves and none of the existing ones fitted. You will also find us written as Out of Dark.

Fix: notifications and gallery picker

Because of a build error, version 1.3 shipped without the part that handles phone notifications and picking a photo from the gallery. This version puts both back.
