Who needs a dedicated UWP app to track all your crypto when there's a perfectly good solution available for free at the tap of an Edge favourite? In this case a PWA (Progressive Web Applciation) that fits the bill perfectly. The name? No, 'hodler' isn't a typo - 'hodl' stands for 'Hold on for dear life' as is part of the crypto-currency scene!
Of course, you can turn this into an 'app' yourself with PAWA or just pin it 'as is' on your Start screen. It's up to you. If you're confused by the different PWA options then check out my feature here.
The syncing across devices is low-tech but ingenious - a simple text phrase to type into each!
Here's Coinhodler PWA in action:
It's trivial to create a portfolio, no account needed, just add your holdings and any notes...
Your 'Hold on for dear life' portfolio value is plotted and totalled accurately - and you can see everything in the cloud on any other browser tab on any other computer by typing or pasting in your backup phrase. Very clever! (Don't worry about me screenshotting this phrase, it's not a real portfolio and I haven't got that much crypto!!)
