CoinDetect: Euro coin detector v1.8.1 [Premium]
Requirements: 4.2 and up
Overview: CoinDetect makes euro coin recognition easy – just snap a picture of a euro coin with your phone camera and the app will tell you the country of origin the year of issue and other information about the coin


The app recognizes only euro (EUR) coins of European Monetary Union (Austria Belgium. Cyprus Estonia Finland France Germany Greece Ireland Italy Latvia Lithuania Luxembourg Malta The Netherlands Portugal Slovakia Slovenia Spain as well as Andorra Monaco San Marino and Vatican City) for more information see European Central Bank.

To recognise world coins try out our new app Coinoscope – a visual search engine for coins.

CoinDetect uses artificial intelligence and computer vision techniques to automatically locate and recognize the coin in the image.

– Automatic localisation of the coin in the image
– Automatic recognition of ~300 euro coin types both regular coins and commemorative 2€ coins (average accuracy 97-99%)
– Detailed information about each coin (description issue year designer approximate value)
– Coin collection management in section ‘My coins’
– Catalogue of all euro and eurocent coins

– Collection data synchronisation with Dropbox (for backups and moving data between devices)
– No ads

Images of coins are uploaded and stored on CoinDetect server. CoinDetect will not share uploaded images with any third parties. Uploaded images might be used to improve recognition model.
