BaroWatch Barometer vs Barometer on‑Wrist

BaroWatch turns your iPhone, iPad and Apple Watch into a precision barometer. Track pressure changes, spot weather trends and get warned before the storm arrives. WHY BAROWATCH • On every device — iPhone, iPad and Apple Watch share readings automatically • Full privacy — no cloud, no servers, no tracking, no ads • Works offline — measurements keep running in the background • Open standard unit — hectopascals (hPa), the unit pilots and meteorologists use CORE FEATURES Pressure measurement • Reads the built-in barometer in iPhone, iPad (iPadOS 17+) and Apple Watch • QFE (station pressure) and QNH (corrected to sea level) • Automatic altitude correction via GPS — or set your altitude manually • Optional manual calibration offset Charts & visualization • Line, bar and area charts with smooth gradients • Color-coded bars show falling, stable and rising trends • Adjustable time ranges from 1 hour to 48 hours • Tap any point for the exact value, time and source • Day stripes for a multi-day overview • Freely configurable color thresholds for high and low pressure ranges Apple Watch • Native Watch app with the full chart history • Complications for Inline, Circular, Rectangular and Corner • Background updates keep your readings current Widgets • Home Screen widgets for iPhone and iPad with a sparkline chart • Lock Screen widgets in Inline, Circular and Rectangular Alerts • Local notifications when pressure changes rapidly • Independent thresholds for falling and rising pressure • Adjustable observation windows (15 min to 3 h) and repeat cooldowns Multi-device sync • iPhone ↔ Apple Watch: automatic via WatchConnectivity • iPhone ↔ iPad: peer-to-peer over local Wi-Fi or Bluetooth, paired with a 6-digit code • No internet connection required Background refresh • Optional background location keeps the barometer running while you walk, drive or sleep • Smart wake-up whenever your Apple Watch syncs Privacy by design • Pressure and altitude data stay on your device • No analytics, no third-party SDKs, no ads • GPS altitude lives in memory only — your exact position is never stored Available in 29 languages. Whether you're hiking, fishing, sailing or flying — BaroWatch gives you precise data and full control over your privacy.

Feature Highlights Dual‑display Barometer & Altimeter All‑in‑One ‑ Shows real‑time barometric pressure and altitude simultaneously, no need to switch between multiple apps. ‑ Dual pressure readout: raw sensor value from Apple Watch and ISA standard pressure calculated by altitude. Ripple background animation visualizes pressure level intuitively. ‑ Displays weather symbol alerts when rapid short‑term barometric changes suggest possible weather shifts (for reference only). ‑ Merges Watch‑built‑in altitude and GPS altitude. Fine pressure variations dynamically calibrate altitude for higher precision. ‑ Records pressure & altitude changes, visualized with numbers and scales. Long‑tap the change value to reset. ‑ Auto‑calibration triggers when deviation against system altitude becomes large, balancing overall accuracy and sensitivity to subtle variations. ‑ Tap pressure value to toggle units: hPa, inHg, mmHg. Altitude supports meters / feet. Rich Watch Face Complications ‑ Circular complications for pressure and altitude for quick glance. ‑ Stack‑able rectangular complication tracks 24‑hour pressure‑altitude trends with current readings. Keep it on watch face to enable continuous logging.
