Evidence

Rainbow documents radar/satellite-based precipitation output with a four-hour horizon and minute-level updates, delivered through map, app and alerts. That defines useful weather information and temporal limits. No comparative forecast accuracy or safety benefit is verified by this assessment.

Limits: Source-researched AI assessment reviewed by a separate native AI worker. No hands-on product test or human verification is claimed.

Page date hints100/100

A copyright year is a weak sign of upkeep. It does not prove the content is current.

Checked Oct 18, 2026.

Policy links do not verify a company's conduct. An HTML response time is not application speed. Tracker and accessibility checks miss behavior after page load. Copyright dates do not prove product upkeep.
