Advance warning alerts of incoming geomagnetic storms
SolarShield is a simple alerts-first app without all the fluff. We do alerts first! Most solar storm apps tell you too late, if at all. SolarShield will usually give you 15 to 40 minutes of advance warning so you can unplug or shield critical electronics. Uses AI (machine learning) models and data from multiple sources including space based observations to provide accurate estimates before they arrive. Protect yourself from the next Carrington Event! The app shows recent history and upcoming predictions in an easy to read chart. You can enable multiple notifications for whatever levels concerns you.
