SkyLogger vs Pressure Altimeter Tracker

SkyLogger is a program for obtaining and storing flight data. The program is especially adapted for the usage by glider, hangglider and paraglider pilots. 
SkyLogger obtains the geodetic positions of the pilot during the flight and stores the data. Furthermore, the pilot is able to see during the flight the elapsed time, the distance to the take-off as well as the current ground speed and climb rate. A compass rose is indicating the current flight direction.
 For competitions the pilot's and the aircraft's name, the aircraft's ID and the to be flown route can be entered.
 During the flight the direction and distance to the next waypoint are shown on the display. After finishing the flight the stored geodetic data together with the data for the competition can be converted into the common IGC file format. Additionally, also other popular formats like GPX and KML are supported. The created files are stored on the iPhone or can be sent to servers or other computers. SkyLogger supports besides others the following features: - control by Apple Watch; - main data visualization on Apple Watch; - cockpit / instrument view; - 2D & 3D flight data visualization; - downloadable map data; - large and individually adaptable instruments on a moving map allow best viewing comfort; - north or in flight direction orientation of moving map; - live tracking support for Leonardo or Vgps servers - visualization of previously flown flights as track traces on moving map; - visualization of airspaces with user defined colors; - instrument showing the distance and direction to the closest airspace; - 3 axis acceleration measurements; - tracked flights are stored in highly efficient internal database; - default flight parameters can be stored and retrieved to make flight information entering for competitions easier; - SkyLoggerXXL supports common file formats like IGC, CSV, GPX and KML; - IGC files created by SkyLoggerXXL are OLC conform and can directly be sent to Leonardo, XCCup, XContest and XC globe based OLC servers; - calculation of XC points for FAI triangle, triangle and free distance over 5 points; - XC analysis (determination of FAI triangle areas); - printing of flightbooks, flight information and statistics - all diagrams, maps or charts can either be e-mailed or copied for incorporation into other apps; - integration of SkyView database for exchanging waypoints; - support of FlyNet accessories; - support of SensBox; - weather data history of selected weather stations for the last 48 hours; - online wind speed and direction visualization on maps for selected weather stations; - visualization of hotspots; - visualization of regions with thermals; - visualization of climb rate traces; - and much much more! Warning: Continued use of GPS running in the background can dramatically decrease battery life.

AltiTracker runs automatically in the background and keeps track of altitude changes in real time. The app's interactive graphs let you see and explore altitude changes and trends over time. With our Live Activities feature, AltiTracker shows your current altitude even when you phone is locked. You can select either sea-level operation or a relative altitude mode that tracks your altitude relative to a selected reference altitude (for example, your altitude relative to your base camp). Optional CSV export/import capabilities let you save your altitude data at ultra-high one-second resolution, and you can explore previously saved CSV altitude data directly in the app. The included Watch app can run stand-alone on your Watch fully independent of your iPhone. Our Watch app also let you easily adjust all key settings such as reference pressure or relative altitude. Real-time stats let you track your total climb/descent info, min/max altitude, vertical speed, and direction. You can set your sea level altitude or pressure manually, or use the GPS feature to obtain a reference altitude automatically. Our Live Background feature helps ensure that you maximize battery life by automatically turning off operation after the desired background runtime period. And our climb sensitivity feature helps minimize the classic problem of weather-based altimeter "drift" between active climbs. For mariners, our app can even estimate wave height and distance between waves. And for good measure, we included our NOAA/ICAO station-based weather data along with our amazing wind speed analyzer. As you can see, we set out to build the most advanced pressure-based altimeter app out there and we hope you give it a try!
