BaroLog

Pressure is always changing, but a single reading rarely tells the whole story. Baro Log turns the barometer in a compatible iPhone into a record you can look back on: the pressure at your location, the direction it moved, and the notes that give a day some context. Open Baro Log whenever you want to take a reading. Choose a 3, 6, 12, 24, or 72-hour view to see the line take shape, and use the three-hour change to understand whether recent readings have been steady, rising, or falling. It is a view of measurements already taken, not a weather forecast. Set your preferred unit: hPa, kPa, inHg, or mmHg. Add your local elevation when you want to compare sea-level pressure. Mark a weather change, an outdoor session, a catch, or your own note beside the chart. When you need the raw history elsewhere, export it as CSV. Everything stays on your device. Baro Log has no account, no feed, and no server collecting your readings. It records pressure while the app is open, so the timeline is an honest record of the times you chose to check in. Made for people who spend time outdoors, pay attention to local conditions, or simply want a better way to remember what the air was doing around them. Requires an iPhone with a supported barometric sensor. Readings can be affected by the device and its surroundings. Baro Log does not provide medical advice, health predictions, or weather forecasts.
