## Description

**Barograph** turns your iPhone or iPad into a real-time atmospheric pressure tracker and barometer data logger. Monitor pressure with dynamic charts, view trends, set high and low pressure alarms, and receive notifications when conditions change.

The app supports background data logging, relative altitude tracking, optional sea-level-adjusted pressure, and CSV export for analysis or sharing. Barograph is useful for weather observation, hiking and elevation tracking, aviation, scientific research, and monitoring pressure trends that may correlate with migraines.

## Review summary

Summary: Users praise Barometer Graph for real-time, sensitive iPhone sensor data and ongoing development with a modern UI. The alarms and unit options plus cross-location trend tracking provide clear value for migraines, travel, and weather insights. Common drawbacks include unreliable background updates, privacy-permission friction in recent builds, ads despite purchase, lack of calibration controls, and inconsistent history/export behavior. Overall it’s a strong, feature-rich tool with caveats related to background operation and calibration.

### Pros

- Real-time, high-sensitivity pressure data from the iPhone barometer.
- Active development and regular updates, including a modern UI (Liquid Glass).
- Rich feature set: alarms, multiple units, and long-term trend viewing.
- Practical value for migraines, travel, and elevation tracking.

### Cons

- Background data updates are unreliable, often requiring the app to be foregrounded to refresh data.
- Recent updates require Motion & Fitness permissions, raising privacy concerns with no clear opt-out.
- Ads persist after purchase / license not consistently recognized.
- No calibration/offset controls for local pressure, reducing accuracy for some users.
- History/plotting behavior is inconsistent (history not always shown; changing units can erase history; limited export/zoom).
