Barometer & Altimeter vs Attendance Tracking MCAA

Know your elevation. Follow pressure changes. Keep a useful record of your hikes, climbs, stairs and everyday observations—with clear readings on iPhone and iPad, plus Apple Watch, widgets and Live Activities on supported devices. • Current altitude above sea level, with relative gain and net change kept separate. Check the reading source and freshness; authorized GPS can provide a fallback where available. • Start, pause, resume and save a recording. Authorized background recording keeps a session going while you use another app or lock your phone. • Find, rename and favorite saved recordings, add notes, compare charts and share data as CSV. • Check your wrist, widgets or Live Activity. Use Siri and Shortcuts to read, record or open saved sessions; interactive controls are available on supported OS versions. • Keep familiar metric/imperial units, Set Zero and pressure-reference calibration. Choose automatic weather, manual reference or a nearby US weather station where available. Readings depend on device hardware, permissions, source availability and conditions. Widgets and complications refresh on the system's schedule, not continuously. Watch recording controls need a reachable iPhone; phone-free Watch recording is not included. Saved history and supported local readings work offline; weather and station updates need a connection. HowHigh is for observation, not certified navigation or safety-critical guidance.
