Watch out for eSteem, when Login in the App demands not only your private posting key but also your private transaction key (I´ve tried to only enter the posting key and it didn´t work) meaning that if they would store that key they would be able to wipe out your steemit balances !
In my opinion I wouldn´t trust the App and I´m not going to use it.
Build your own opinion.
Thank for the heads up
