About

Is it raining where you're heading? Will you need that rain jacket? RainUp is a weather data field that gives you real-time rain information for where you are and where you're heading. Purposefully simple to read, understand and act on. Just the information you need during a ride - without fancy graphs, clutter and a paywall. It uses your location, speed and heading to estimate where you'll be in the next 30–60 minutes, then continuously updates the rain forecast along your projected route. The screen updates every second. The rain forecast refreshes every five minutes, and every time whenever you make a significant change in direction. Features: - Current rain conditions - Rain forecast at your projected location - Estimated rain arrival and clearing times - ▲ moving forecast (points to the direction of the forecasted rain) - ⊙ stationary forecast for current location - Six-hour sparkline for rainfall trend - Data staleness indicator Rain intensity wording: - Dry/Clear: no rain - Drizzle: up to 0.2 mm/h - Light rain: 0.2 – 1.0 mm/h - Moderate rain: 1.0 – 4.0 mm/h - Heavy rain: over 4.0 mm/h Six-hour sparkline's rain intensity height - Empty: dry hour - Short bar: Drizzle (~10–25% of full) - Medium bar: Light rain (~25–50%) - Tall bar: Moderate rain (~50–75%) - Full bar: Heavy rain (75%+) RainUp uses forecast data from Open-Meteo. Forecast accuracy depends on: - GPS accuracy - Phone connection and data availability - Availability and resolution of forecast data in your area - Rapidly changing local weather conditions Supported devices Edge 530, 540, 550, 830, 840, 850, 1030, 1040, 1050, Edge Explore 2 and Edge MTB. This is a free app, and I’m happy to improve it based on your feedback. The most useful feedback is a detailed description of a behaviour or a scenario, potentially with a short video showing the problem you encountered. This helps me nail down and fix issues in future releases. Please send your message to [email protected]. If you find RainUp useful, you can buy me a flat white.
