Make sure to cancel/delete your uber account before uninstalling the app.
One Bus Awayis the public transit app I use (Seattle/Puget Sound area, it’s on IOS and Android!), and it works for a few other cities too.
I also recommend saving your local taxi service’s number into your phone just in case. (Seattle Yellow Cabis 206-622-6500, they also have an app on IOS and Android.)
