Keep It Simple Stupid

I enjoy the format of this app. Perfect for the person who knows where they are going and just needs to check the traffic. It doesn’t have a bunch of junk all over the screen, like where every Starbucks is and other franchises. I also like that is stays facing North. Other apps rotate just when I try to zoom in and out. So if you have ever looked at a real map in real life and are t scared of it, this map is the right route.

Accessibility is messed up big-time!

Although I am blind and don’t drive, I used to use sigalert to give me information about road conditions while using paratransit services for my long daily commutes to work. I could then pass on that information to the drivers so that they could take alternate routes if need be. Quite some time ago the app used to have clearly-labeled buttons for various controls that the VoiceOver screen reader that’s built into my iPhone could readily identify. Now those buttons aren’t clearly identified; Voiceover just gives me meaningless information when it finds one of those buttons. Developers: we blind guys may not drive but a good number of us out here do travel to work and play and we like handy road information, too, so c’mon, fellas, get your act together and follow the existing accessibility guidelines for apps. Don’t just release an update with unlabeled cutesy eye candy graphics that don’t mean squat to us blind users.

Great App informative

I’ve been a professional Chauffeur in LA for 30+ years and this app is an absolute essential tool.
Don’t be intimidated by the 1 star reviews, seems that what they are complaining about is that is not a GPS system. It operates just like all informative apps do, they rely on peer to peer input. It just takes a moment for the person to update the status of an accident, floods etc. if one drives by an incident and they do not report it, that’s not the systems fault. A must have app for what’s going on in the direction that your going to or happen to be on.
