About
HowHigh is a free barometer and altimeter toolkit for following altitude and air-pressure changes. See live readings, record sessions, and compare history on iPhone and iPad—without a subscription. USE HOWHIGH TO: - View live pressure, altitude, rate of change, elevation gain, and sea-level adjustments. - Record hikes, climbs, hills, stairs, weather observations, and experiments. - Review session history, compare recordings, and explore interactive charts. - Share results or export recorded data as CSV. - Choose manual calibration, optional WeatherKit calibration, or nearby NWS station calibration where supported. - See the active measurement source and sensor-confidence context alongside each reading. - Switch between metric and imperial units. Your recorded sessions stay on your device until you choose to share or export them. Core readings and saved history remain available offline; online calibration sources require a connection. HowHigh is designed for everyday observation and exploration. It does not replace certified instruments or safety-critical guidance. Track how altitude and air pressure change over time—all core features are free.
