I dont know if MEW already has a mobile app but if nothing like that exist, then i think its about time the developers develop something like that for easy use. Guys what do you think
I think they already developed the mobile wallet version.
If you try to login in myetherwallet website, it has option for MEWConnect.
Click it, and you will see a link to download the mobile wallet of myetherwallet in playstore for Android, or appstore for Apple.
