Providing all your mates have a smartphone with Google Maps, this little FlareGun app could shave valuable minutes off directions-related pain when out on the town. It sends a user's exact location on Google Maps via SMS, in the form of a link.
The receiver can then click the link, and see the drinking hole or restaurant right there in Google Maps, whether they have FlareGun installed on their phone or not. Available in the App Store now, it's 99 cents. [iTunes]
