Android widget for BTC/ETH pair, does it even exist?

I've just installed and uninstalled 5 apps from the playstore, it's a drag. I've been trying to find a way to display the ETH/BTC pair on my home screen and all the apps seem to just offer EUR or USD pairing for any cryptocurrency.

I'm still thinking it shouldn't be that hard. Or is it? Why arent there any big name apps that offer this, do people just want the USD price on their home screen?

So, I'd really appreciate it if you can point me in the right direction of how I can do this, preferably an app of course!
