· Cloud cover (with layer breakdown)
· Astronomical seeing
· Atmospheric transparency
· Temperature and humidity
· Rain / snow

• Moon phase and elevation.
Tools:
• Aurora forecast, with worldwide and local data/maps.
• ISS and satellite passes for your location.

Display
Three display modes: 7Timer icon/graphic view, color-stripe view, or raw text. The left panel can be switched to icons, and summary icons and cloud layers are configurable in settings.
This app will always be ad-free, with no in-app popups asking for reviews. If you would like to support it and the 7Timer service, Xasteria Plus adds an Apple Watch app, Home Screen widgets, OpenWeather real-time forecasts, Apple Weather, night vision mode, lunar calendar, solar eclipse tools and more.
