I ride a lot (cycling and hiking) and I kept running into the same frustration: weather apps give you a forecast for a city, not for a mountain pass you'll reach at 2pm after 5 hours of climbing. I wanted to know if that storm would hit before or after the exposed ridge. So I built this. The core idea was simple: parse a GPX, sample points along the route, and fetch the forecast timed to your actual arrival. What surprised me was how much the little details mattered: wind direction on a climb feels very different than wind direction on a descent, so I added animated arrows. The elevation chart needed to sync with the map cursor. Pace presets (hike vs road bike) changed forecasts dramatically. Very simple app: no backend, no account, no tracking. Just drop your file and go. Would love to hear how others use it and what sports/activities you're planning around!
