Yo PH! I wanted to make something that was super easy to keep up to date and provide an overview of all your coins in one place (instead of having to check out multiple exchanges, or maybe you're using a hardware wallet). What I landed on is an interface where you just add what coins you're holding and what you've paid for them. After you add some coins you'll see how much money you've made in the last day, week, month, etc. I also found a lot of similar tools are focused on Mobile, which is great to checkout when you're on the go, but kind of a bummer for adding / updating what you're holding. For that reason Folium is a responsive web app, meaning it works great in your browser, but also on any tablet or phone you're using. Hope you dig it!
