BaroLog: Barometer & Alerts

BaroLog is a barometer app and barometric pressure tracker. It shows the air pressure, where it is heading, and when it is about to drop. It uses your phone's barometer and the forecast for your area, keeps everything on your phone, and never shows ads.

WHY PEOPLE USE IT
Many people feel weather changes before they see them: headaches and migraines, aching joints, fishing and hiking plans. A falling barometer is the early sign. BaroLog makes that sign easy to read and can tell you before it happens.

LIVE PRESSURE
• Your phone's barometer, smoothed so a slammed door or an elevator ride does not move the number
• Sea-level pressure that matches weather reports, or the raw pressure at your altitude
• hPa, inHg, mmHg or kPa
• 3-hour trend in plain words: rising, steady, falling, falling fast
• No barometer in your phone? BaroLog shows the forecast pressure for your area instead

FORECAST AND HISTORY
• Measured pressure and the 24-hour forecast on one chart
• "Forecast: falls 6 hPa by 3 PM" when a drop is coming
• 3-day history free, 7 and 30 days with Pro

HEADACHE LOG
Tap "Log headache" and the moment is marked on the chart, so you can see whether your headaches follow pressure drops.

PRESSURE-DROP ALERTS (PRO)
Choose the drop size and the time window, for example 5 hPa within 6 hours. BaroLog checks your readings and the forecast and sends a notification. iOS and Android decide how often background checks run, so an alert can arrive late; the forecast part usually gives hours of warning.

FREE AND PRO
Free: live pressure, trend, forecast, 3-day history and the headache log. BaroLog Pro, a single in-app purchase: drop alerts, 7 and 30 day history, CSV export.

PRIVACY
No account, no ads, no analytics. Readings stay on your phone. To fetch the forecast, BaroLog sends only an approximate position (about 10 km) to MET Norway, the Norwegian Meteorological Institute.

BaroLog is not a medical device and does not diagnose or treat any condition.
