## Description

Magnetology is a Chrome extension that lets you watch forecasts of geomagnetic storms and monitor Earth's geomagnetic field. It surfaces the Kp index and related space weather indicators, using NOAA data to keep you informed.\n\nWhy it matters: geomagnetic activity can influence health and critical systems such as communications, navigation, and power. By following forecasts, you can plan decisions, reduce physical stress, and protect personal health and devices. The extension credits NOAA data and includes localization contributions.

## Review summary

Users generally praise Magnetology as a valuable tool for drone pilots and GPS-related planning. The app offers clear geomagnetic data, KP Index alerts, and simple, accessible information that many reviewers use daily for safer flights and better satellite performance. It is appreciated for ease of use across iPhone and iPad, and for providing critical data before flights. However, some reviewers report accuracy issues and note that displayed data is often an estimate rather than current values, with requests for tighter data validation and better time markers. Overall, it's a highly useful tool with noted reliability caveats.

### Pros

- Great for drone pilots and pre-flight safety checks.
- KP Index and geomagnetic alerts help anticipate GPS/GNSS issues.
- Easy-to-read, simple interface with clear geomagnetic data.
- Fast, reliable updates and generally up-to-date information.
- Works well across Apple devices (iPhone and iPad) for flight planning.

### Cons

- Data accuracy and reliability concerns: not always accurate; some readings don't match official reports.
- Data presented as estimates rather than actual/current values, with requests for tighter data validation and better time markers (e.g., vertical lines and UTC).
