About this app

COINVENTORY is the ultimate app for collectors and investors of bullion coins and precious metal bars.

With a simple and intuitive interface, users can conveniently manage and analyze their collection from any device.

Main features:
- Inventory registration: Users can add their coins and bars by selecting them from the official COINVENTORY catalog or, if they are not registered, create them manually. Once verified by the team, the new items will be added to the app's global database.

- Performance and prices: Check the spot price per gram of precious metals according to the LBMA, updated hourly and showing the change from the previous price.

View the evolution of the spot price using dynamic graphs.

Set up custom alerts to be notified when the metal or item reaches a specific value.
See the total spot price of your collection, differentiating between coins and bars, as well as by metal type. When registering each piece, the user can indicate the price paid, and the app will automatically calculate the profitability and current value of the investment.

- My World: An innovative interactive world map displays the countries of origin of the pieces in the collection. Each territory is automatically colored as items are added, allowing users to visualize the geographical diversity of the collection at a glance. By tapping on each country, the user can see the type of metal, quantity, and items they own.

- Premium Calculator: This tool allows users to easily calculate the premium (difference between the purchase price and the spot value) of any coin or ingot. With this information, users can evaluate whether a purchase or sale is advantageous, optimizing their investment decisions.
