there is an app for android smartphone in playstore called blockfolio, i think it's the best app to make a crypto portofolio, very much alts available and price updated every single second
Coinomi is also a convenient way as it support many coins and they have quick overview to see worth of all portfolio and coins. But blockfolio is a bit more decorated how to say with all of those graphs built in and it supports all coins if not most of them.
