The fake app doesn't have any relation to the electronic purse for storing ETH and other coins. This is reported by TechCrunch.
Before fake MyEtherWallet app Nam Le created two gaming applications about combat pandas, but never had anything to do with electronic wallets or other crypto-currency applications.
This is NOT US. We have file reports and emailed and reported. Would appreciate the communities assistance in getting these scamtards out of our lives.

The application allows users to create or import wallets for storing crypto-currency assets outside the exchanges. At the same time, an unknown developer is more likely to gain control over private keys to manage wallets.
In addition, the application is built on the basis of open source, but the developer made it paid, trying to monetize public technology.
It's not clear how the application managed to get through the AppStore check and get into the top rating.
