• Seven day hourly forecasts, updated hourly.
• Low, medium, high and total cloud cover.
• Moon rise/set times and phase.
• Sun rise/set and transit.
• Civil/nautical/astronomical darkness.
• ISS pass-over information.
• Automatically provides a forecast for your current location.
• Save favourite locations for easy access.

Updated hourly. Frequent hourly updates are important because often the clear spell between showers provides excellent seeing and 30-minutes under a clear sky with a grab-&-go telescopes is pure gold!
Did you notice the ISS pass-over information? The times are precisely calculated for your location and displayed alongside the cloud forecasts so it has never been easier to observe. It is our favourite feature :-)
Also includes regular weather data (wind, rain, frost, temperature, dew point, etc) so perfect for those wanting a detailed weather forecast, without cutesy graphics.
We have had a lot of fun building and testing Clear Outside and are keen to to develop it further so if you find it useful or have suggestions, please let us know.

Promising but dated app
This app was designed for smaller iOS devices and hasn’t been updated for modern, larger iPhones. When, for example, I open it on a iPhone X Max, I get a black bar at the top and bottom of my display, not availing itself of the full screen.
To make the app avail itself of the full screen would is a fairly trivial change and the fact that this hasn’t been done suggests that this iOS app may have been neglected for the past few years.
The app works, but is a tad outdated.
Has potential, but needs work
This forecast app is usually accurate, but it can be difficult to find locations in the US. Since it’s a UK based app, it lists the county in the search function and can be difficult to actually select the right town you’re trying to search for. In addition, I don’t know why they didn’t include the seeing forecast from the Canadian astronomical forecast, which is where this app pulls data from. It would be so easy to implement, but seems like a big oversight. It would be even better if users were able to input their own coordinates of their location. Lastly, it doesn’t let you easily update your home location without deleting it and re-entering it again. If they fix these issues, it would be a much better app.
Developer Response ,
This is incorrect - the app does not pull any data at all from the Canadian astronomical forecast. We do not include a seeing forecast because we are yet to find one that is accurate and reliable enough to use.
You do not have to delete a location to make a different location the home location. You simply edit the location you wish to be the home location and check the home location checkbox :-)
We will be improving the location search options in a future update including the ability to add your current GPS location or enter the coordinates yourself manually. For now you can manually enter the coordinates, simply choose any location to add and then edit the description and coordinates in the next screen.
Just tried it out. Can't believe they didn't test their app. When you go to select a location, it actually selects the one below it. I tried a few different locations and they all did the same thing. So to add a location I have to tap on the one on the list above it.
Its location search itself doesn't always work. I looked for Salem and nothing showed up. Then I did a search of "Salem, M" only because I know what county it's in. And it finally brought it up as an option.
Buggy app which makes me distrust the weather readings it provides for an area are incorrect.
