Updated hourly, because frequent updates matter! Often the clear spell between showers provides excellent seeing, and 30 minutes under a clear sky with a grab-and-go telescope is pure gold. Our favourite feature? The ISS pass-over information is precisely calculated for your location and displayed alongside cloud forecasts, making it easier than ever to catch the station overhead. No cutesy graphics - just detailed, reliable weather data presented clearly for serious observers. We've had a lot of fun building and testing Clear Outside and are keen to develop it further.
