## Description

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.
