The open source project I stumbled upon that allows you to run Android apps on PC is Waydroid....it takes a container-based approach to running a full Android system directly on Linux
If you can get the app. I looked at Waydroid and other apps, but discovered that app I needed was only on the google play store. (I want to see when my kid's bus will arrive - there is no web site, just an app. I suspect it needs google logins or something to use, but I gave up before I figured out how to download the .apk)
