Jolly Logic AltimeterThree;

For flying hobbies only. AltimeterThree is a flight altitude recorder that is controlled by your smartphone or tablet. If you would like to collect and share flight data, then this is the altimeter for you. It is small enough to go almost anywhere, and it can used for almost any flying activity. It is the first flight altimeter approved as an official Made for iPhone/iPad accessory by Apple. It plays nice with Android, too. It captures your notes and observations on each flight. You can view an interactive graph of altitude (and for certain sports, 3-axis acceleration) and produce a Microsoft Excel spreadsheet of flight data for further analysis. If GPS is enabled on your mobile device, the location of each flight is saved, and can be viewed on a map. Integration with Facebook, Instagram, Twitter, and Flickr allow you to share your flights with just a tap. AltimeterThree includes a recharging cable, and can be recharged from any USB port. We suggest you install the app before purchasing the altimeter, to make sure your device is compatible.
