Designed for skydivers and wingsuiters, Skydive Logger automatically records your jumps and captures detailed information so you can geek out on data back on the ground. Each jump log includes: - Exit and pull heights - Time in freefall - Vertical and horizontal speeds - Flight path displayed on a map - And lots more... Skydive Logger is packed with loads of additional features: - Jump signing so you can throw away that paper logbook. - AirPrint so you can print jump logs, including signatures. - iCloud support to back up your jumps and make them available on larger devices, including iPads. - Jump export to JSON and kmz formats for Google Earth™ so you can view your jump in 3D. - Apple Watch app for in-air information like the distance and direction to the landing area (requires 200 jumps). - Configurable in-air audio commentary telling you your speed, glide ratio, direction to landing area and much more (requires 200 jumps). - Access HealthKit to plot your heart rate against your jump data, so you can see how calm you were at key points. *Please note:* For recording jumps Skydive Logger works best on iPhones that include a barometer. It can also be installed on other iOS devices for viewing the data. Skydive Logger should only be used by skydivers with an FIA C-license or above in the UK and is not a replacement for jumping experience or common sense. Skydivers and wingsuiters outside of the UK should check local regulations or speak to an instructor before use.
