Weather apps make sense out of millions of parameters, but they cannot tell you what the person standing one valley over is actually looking at. The forecast in your pocket is the forecast for everyone in your ten-kilometer cell. VYU turns every phone into a directional weather webcam. A photo plus the compass heading from the device's orientation sensors becomes a view-cone on a shared map, pointing exactly where the camera was aimed. Three Claude Managed Agents on Opus 4.7 do the work, on two clocks. When you submit a photo, a Classifier reads it against a phenomenon taxonomy and a Reconciliation agent fires alongside, checking the image against DWD radar, EUMETSAT MTG infrared and lightning, and the Open-Meteo forecast. What comes out is a verified report. When you ask a question, a Deep Researcher answers it against your own report and a per-cell memory of what other contributors nearby saw. If the answer mentions the cool wind off the lake, it is there because someone there felt it. The agent inherits. One photo earns one question. A fair trade. Tit for tat.
