We have covered Google GLASS and smartphone compatible guns here in the past. Not everyone is ready to buy a new rifle just for its smart features. The InteliScope Pro and its companion app help make your existing rifle smarter. The InteliScope lets you mount a smartphone to your rifle and get critical information from its companion app.
The mount fits on any Picatinny rail and can be adapted to fit other mount styles using an adapter. The companion app has a rifle scope with over 10 different reticles. You also get GPS location for video recording, timer, stopwatch, and a whole host of other useful features. The companion app runs on iOS/Android devices.[where to get it]
