Slow and efficient

This app is so slow that by the time you look up a bus, you missed it.

Pretty good for my needs

I use AC Transit buses frequently, and this is better for me than the Transit app in that it lets me look out across the entire system, not just the stops closest to me. That said, I would really prefer if the bus line schedule (of predicted stop times on the selected line) were also embedded in the app, instead of linked through the website.

App won’t open on iOS 26.0.1

It force closes the app the second you open it. Redownloaded the app and restarted my phone, still same issue

Always crashes, used to be great

I used to rely on the app for commuting, but in the past month or so, it always crashes when I try opening it. I'm using newly updated iOS.

STILL!! Completely Broken

As of this week, the app crashes every time I open it. I’ve deleted and redownloaded it several times and nothing works.

Any chance y’all are ever going to fix this issue? It seems like it’s a pretty common ongoing issue for a lot of users. The app was imperfect, but it was generally the best way to know when your bus is coming. I’m finding that every maps app is completely unreliable, and 511 is very clunky. This has caused incredible inconvenience and numerous unsafe situations for me, and I’ve ended up spending 5x what I intend to on Lyfts because AC Transit itself is so unreliable that I keep ending up stranded. If the buses that are supposed to come regularly just come whenever, and I’m frequently stuck waiting 45 minutes for a 57 that was supposed to come 20 minutes ago, the ABSOLUTE LEAST the county could do is… maybe provide a bare minimum working app so that I know exactly when and where I’m going to be left to wait astronomically longer than promised?

If you need more riders to secure more funding, ease of use is kinda the bare minimum you need to provide. This failed app seems like a feature of the downward spiral of public transportation in the Bay Area and it’s honestly really sad.
