Key features: - GPX/FIT import and route-timed forecast points, - Road, Gravel, MTB, and City ride profiles, - route direction selection and wind balance comparison, - a map with critical segments and route replay, - outfit recommendations: what to wear, what to pack, and when to change a layer, - thermal preference and optional matching with a local LANC wardrobe, - a saved active route and latest forecast for offline reading, - a Lock Screen Live Activity and Dynamic Island on supported devices, - an Apple Watch app with plans, forecasts, outfit advice, and complications, - optional iPhone GPS with pause/end controls and upcoming-condition notifications, - a shareable PDF report, - Apple Weather through WeatherKit, Open-Meteo, and MET Norway.
