Ratings and reviews

When it works, it's great! You can check when the bus will be at the stop, plan your route, all that good stuff. WHEN. IT. WORKS. Every other week it seems the app is having some issue or another, and, the last few days, the app has somehow lost track of every single bus stop, making it little more than a glorified street map. Even for freeware, this app is unacceptably broken. 09/15/2025 update: Yep. still applies.

This SHOULD be a useful app. However, even when it DOES 'work', the bus schedules are rarely accurate. Lately, and on occasion in the past, the app doesn't even work. As of writing this, the app hasn't been able to 'locate' any bus stops for seversl days, making it impossible to access the bus schedules. Sad and frustrating when Google Maps is more reliable than either the sun tran app or official schedule.

One of the most useless app on the play store. The app does not work at all as intended. 6 months ago I was able to see stops and times, now it barely gets my location correct. It no longer shows you what stop you are at, let alone when the next bus will come. When you try to Plan a Trip, the app says you have to enable billing on Google. Your not even able to create an account. Don't waste your time downloading this app.
