MEWconnect used to be the mobile app that connects MEW users to their wallet directly from their smartphones. However, this app has been removed from IOS and Android on the 13th of August, 2020. The reason for this is that; MyEtherwallet launched a new mobile app dubbed "MEW Wallet" which integrates both the MEWconnect function and other advanced features. In other words, to access "MEWconnect" you will have to download "MEW Wallet" on your mobile phone.
