Pizza Navigator is a free Android app for devices and watches, that quite simply tells you exactly how close you are to the nearest pizza restaurant. It's as simple as that. The app shows the five closest pizzerias to your current location no matter where you are. A compass points you in the right direction (a gem for when you are walking through a city) and gives an exact distance to said pizzeria.
So as you can see, the nifty little compass arrow is a pizza slice that points you in the direction of the nearest pizzeria. If you're not interested in the first pizzeria, simply swipe left to view the next closest restaurant.
I learned pretty quick that the compass is approximate, and not always dead on. However, if you are interested in getting turn by turn directions, all you have to do is click the map icon, and you can get driving or walking directions instantly via Google Maps.
A Pizza app that is looking for pizza even when I'm not. What a novel idea! The app is currently free at the link below.
