some etherium erc20 wallet out there are also supports this feautre and i think using a myetherwallet.com is not really safe anymore because  almost everyday there were always reports about users that there coins were get lost and someone has just withdraw it without their permissions. no matter what you choose android or desktop version make sure you just choose the one with a downloadable version and not a browser or online based as it more prone to exploits and hack attacks.
