It gives real time guesses for when the next bus should have arrived.
And when you miss your stop it maps your trudging progress back to
where you need to be through construction zones and snow banks.
All it needs now is a screen heater so your fingers don't freeze while
you compose a blog post about it all.
P.S. If you're at the bus stop at Moodie and the Queensway and waiting for an eastbound Queensway ride like the 101 make sure you press the button that looks like a cross walk button. Otherwise the secret light a kilometre away on the Queensway doesn't light up and no bus will exit to pick you up. Much hilarity ensues as you decompose by the side of the road over the next few days.
