METAR Decoder

Snap a photo of a METAR, or paste it in, and get a clear plain-language breakdown. The photo reader runs on your device — nothing is uploaded.

Photo reading uses on-device text recognition — no upload, no server. It's a best-effort read: screens and clean printouts work best, and you should always check the extracted text and fix any misread characters (an OCR can confuse 0/O or 1/I) before trusting the decode.
