I found a service that at least offers to import balances from many exchanges: https://coinbalance.org/
It's just a fraction of the functionality I was looking for, but it's better than nothing and it does it's job quite well.

Hi folks,

I am looking for a way to track all my crypto currency investments. I already found some services but none of them met my requirements.

Here are the things that I expect from such a service:

• API connection to all major exchanges (I don't want to add everything by hand)
• tracking of all transaction types that are offered by the exchange (deposits/withdrawals, trading, funding, ...)
• no mobile only application (if it has a mobile app thats fine, but I want to use it at a computer primarily)
  
• BIG PLUS: self hosted or desktop application

I'll edit this list if I come up with more requirements.

Can anyone recommend a software or service?

I have 2 questions:

1. are you planning to let the code of the smart contract and the app be audited by an independent third party (aside from the bug bounty program)?
2. will it be necessary to give the savedroid app access to a fiat bank account for the crypto services to work, or will it be possible to just deposit some fiat currency on the savedroid account?
