Park your car and tap “Park Me” to take a GPS reading; on the way back, hit “Where Did I Park” for turn-by-turn directions back to the whip. It’ll work for first-gen and iPod touch users (although not as well, I would imagine) via Wi-Fi and cell-tower positioning but 3G users will get turn-by-turn directions via GPS. Sure, you could just drop a pushpin in Google Maps, but part of the charm of these apps is going to be the simple execution of simple ideas, Xbox Live Arcade style. Gizmodo recommend just remembering where you’ve parked.
