AltimeterThree [iPhone]

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 wirelessly to AltimeterThree using Bluetooth, and continually displays the battery level and status of AltimeterThree from up to 100 feet away. Press Record in the app, and AltimeterThree's highly-accurate sensors begin recording altitude and acceleration.

After flight, the app downloads and displays an interactive visual graph of altitude, allowing you to pinch and zoom to examine every nuance of movement during 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. The app lets you post your flight graphs and flight statistics with friends, colleagues, and classmates 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 the AltimeterThree altimeter from Jolly Logic or one of its resellers.

If GPS is enabled on your mobile device, AltimeterThree will save the location of each flight. Continued use of GPS running in the background can dramatically decrease battery life.
