Baro: Barometer & Altimeter

See the weather turn before it reaches you. Baro reads your phone's barometer and shows live air pressure with a 3-hour trend arrow. One plain sentence tells you what the trend means: steady, rising or falling. Altitude and a bubble level are included. No account is needed, and your readings stay on your device. • Live air pressure in hPa, inHg or mmHg • 3-hour trend arrow and a weather-tendency sentence • Barometric altitude and GPS altitude, with a reset to zero at your trailhead • Two-axis bubble level for shelves, frames, tents and camp tables • Large, readable numbers in light and dark themes • Works without an internet connection What is free: live pressure, the trend arrow, the tendency sentence, both altitude readings and the bubble level. What is Pro: a 7-day pressure chart (recorded while Baro is open), sea-level correction and an extra decimal of precision. Pro is optional and comes as a weekly or yearly subscription, or as a one-time lifetime purchase. The free version shows an occasional ad; Pro removes ads. Baro collects anonymous usage statistics and crash reports to improve the app. Baro needs a phone with a built-in barometer; GPS altitude works without one. The tendency sentence is a simple guide, not an official forecast or safety warning.
