Most cryptocurrency portfolio trackers have a ton of useless information and tabs and historical data and other items most people do not need.

Cryptofolio is the simplest portfolio tracker you will find, simple add the amount of coins you have/bought, how much did they cost you, and BAM, you're done.

Cryptofolio automatically tracks your current profits/losses and investment.

Everything can be accessed in 2 clicks or less, and the best thing about it:
It does not send your information anywhere, no cloud, no server, nothing.
Everything is saved on your phone, no need to login, sign up or save your information anywhere except locally on your device.
