This app helps calculate the standard atmosphere profile. The original data are based on "US Standard Atmosphere 1976". The main features are:
- The data can be scaled by altitude, pressure and density.
- Including altitude, pressure, density, temperature, acceleration of gravity, speed of sound, dynamic viscosity and kinematic viscosity.
- Allows setting sea level temperature for non-standard profile.
- Support saving profile for quick reference.
- Support SI unit system, FPS unit system and also you can custom unit system for your favorite.
- Available data are respectively from -5000 meters to 86000 meters altitude.
- Approximately monitoring and recording local altitude and air pressure (For Reference Only).
- Tracking back the recorded local atmosphere data using locations and timestamps.
- Provide Apple Watch app to monitor and record local altitude and air pressure.
