I am using chrome remote desktop to access to my desktop pc from anywhere and use coinigy is great!, is like team viewer, log me in, etc., but use an gmail account to access. I find it a lot more handy than android apps. (the best android app i try is TabTrader, have great charts)

android client:

Chrome Remote Desktop is a security risk, I would advise against that.
Yes i know, My BTC account is really small (0.05 BTC) I guess i find a more secure way if my account grows.
Good use of thumb: The data on your computer is typically worth more than the computer itself. Always practice safe security! If you practice safety now, you won't have to worry about it when your portfolio grows in the future.
