Cryptofolio is an iOS application to track crypto currencies investments. 10k downloads.I started developing it because I didn't find any app that fits my need. I wanted a simple app that tells my profit and loss of my Ethereum investments.The first version of the app was only compatible with Ethereum and had a basic user interface. It gained some attraction and users asked me for more functionalities.I decided to dedicate a part of my time to improve it and followed the Lean startup method.The last version of the app is compatible with thousands of crypto currencies, real time price update and a powerful user interface.The application is written in Swift and the notification system uses AWS Lambda (NodeJS functions), AWS DynamoDB (database), AWS SNS (push notification) and AWS Cognito (users pool).App Store link: https://itunes.apple.com/us/app/cryptofolio-1/id1097693974?mt=8
