Discovered this app quite by accident a number of years ago, and after eyeing its competition, settled on this one to recommend to people.<p>It did exactly one thing well that I wanted: it looked at my current location and gave me ETAs for <i>all</i> of the nearby lines, MUNI, BART, whatever it was I might need. At the time I was mulling my own ideas about an app, more or less like this, but it dropped from my considerations once I discovered this app.<p>It's been a more consistent companion than my choice of web browsers, mail clients, search engines, note apps, operating systems or whatever, and I've pretty much never felt any need to actually replace it.<p>Some apps just do one thing and do it very well. Kudos to Transit app.
