BaroWatch Barometer
Barometer for iPhone & Watch
$0.99 · Designed for iPad. Not verified for macOS.
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

• Optional manual calibration offset
Charts & visualization
• Line, bar and area charts with smooth gradients

Background refresh

Privacy by design
• Pressure and altitude data stay on your device
