Blue Onyx is a mobil radiation monitoring application. The application is used with International Medcom's Blue Onyx radiation probe. Once paired with a Blue Onyx radiation probe, the application will begin to log radiation data along with the current time and date and your location.

Data is displayed on your iOS device as a graph or on a map. The current radiation level can also be displayed on your Apple Watch.

You can email your data or share via social media. The application can also upload your data to Safecast's world wide radiation data base.

Please note. This application uses GPS in background mode. Continued use of GPS running in the background can dramatically decrease battery life.
