This is the companion app for Jolly Logic's AltimeterThree, a tiny recording altimeter for hobby model flyers. AltimeterThree can record the altitude and acceleration of quadcopters, planes, rockets, kites, hunting falcons, gliders, and helicopters. Essentially anything that flies.This app connects via Bluetooth to AltimeterThree to control it from up to 100 feet away. Press Record in the app, and the altimeter uses its highly-accurate sensors to begin recording the flight, even when it flies out of Bluetooth range.After flight, the app downloads and displays an interactive graph of altitude, allowing you to pinch and zoom to examine every detail of the flight.Want to dig a little deeper into the science and math of your flight? The app can share your flight data in a standard spreadsheet file that is perfect for analysis on your computer back in your lab or classroom.Great flights deserve sharing. This app lets you post your flight graphs and flight statistics with friends, colleagues and clasates via Facebook, Twitter, Instagram, Flickr, and email---all from your phone or tablet right after a flight.This app is free and fully functional, but recording of flights requires the Jolly Logic AltimeterThree altimeter from Jolly Logic or one of its worldwide resellers.If GPS is enabled on your phone, AltimeterThree will save the location of each flight, and allow you to view it on Google Maps.
