I've tried a number of other apps that kind of does the same thing. What I was missing and what I think Cryptohodler does really well is to keep it simple and shows you a nice overview of your total portfolio. For instance, when adding a coin Crypthodler doesn't care at what rate you bought or sold anything. It doesn't require you to sign in or create an account.
The main goal of Cryptohodler is to answer the question "What are my total cryptocurrencies portfolio worth right now?".
I think this kind of data is very personal and I don't want to share it with any third party. So any app that requires me to sign in is a big no for me.
