Rejn

Rejn is the first aniridia-friendly weather app in the world. Built with extreme-contrast modes, oversized type and glare-free surfaces, it is readable for people with aniridia and low vision — and calmer for everyone else.

Rejn is a consumer weather app — not an API, not a developer tool — rebuilt from the ground up around clarity and craft.

Real-time conditions, hour-by-hour and ten-day forecasts, rich animated radar and severe-weather alerts, all wrapped in a quiet, typographic interface that respects your attention. We aggregate 13+ sources and run it through our special ai weather model for the most accurate forecast.

No clutter, no ads, no upsells, no dashboards full of numbers you don't need. Just the sky, presented well — on your phone, in your pocket, every morning.
