Measure atmospheric pressure and altitude using built-in GPS and pressure sensor. Automatically calibrate readings with local meteorological station data. Display current pressure and elevation levels. Save historical data for reference.
Determine using GPS, barometer, or location input. View data on interactive maps. Access real-time altitude readings. Compare changes across locations. Save and share measurements.
Track and altitude without an internet connection. Receive alerts for rapid drops. Monitor altitude changes and weather patterns. Log data for later review. Sync measurements with other devices.
The app displays built-in device sensor values including acceleration, heading, pressure, position, altitude, and speed. It also retrieves location name and elevation from GeoNames, and local weather data from World Weather Online.
Displays current position via GPS with a map and sea level measurement in meters. Converts meters to feet using a calculator. Measures barometric pressure with a sensor for altitude tracking. Alerts for potential flooding.
Displays latitude, longitude, and using GPS. Shows atmospheric pressure and boiling point of water at current location. Provides elevation data above sea level. Offers ad-free experience via in- purchase. No functional limitations.
Monitor and altitude using the device's internal sensor. Track changes to predict weather patterns. Provides altimeter readings for elevation awareness.
Calculate ballistic trajectories with detailed data including 4000 cartridges and 3300 reticles. Visualize trajectories, compare different cartridges, and adjust for barometric pressure, altitude, temperature, and wind.
