## What is Clear Outside?

Reliable weather forecasts for astronomers with an emphasis on cloud cover. 

Features include:

	• 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. 
	• Daytime forecasts for solar observers/imagers. 

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.

### 2/5 — Age Issues

*2025-11-06, version 1.0*

Great app and plenty of useful information but Jesus please just update it!

### 1/5 — Critical Flaw

*2025-10-26, version 1.0*

The fact that you can’t manually enter or edit a negative longitude makes this app an excellent example of worthless design. And this hasn’t been corrected in over four years? Ridiculous.

### 1/5 — Do these folks even use their app?

*2025-09-05, version 1.0*

Just try entering a custom latitude/longitude, I dare you. The keyboard has no negative sign and the longitude is uneditable. I do my astrophotography in remote areas away from the towns and cities in their database (and the reason is Mr Bortle), yet this app is useless for any area outside their databases of high Bortle locations. Test your darn software!

### 3/5 — Devon!!!!!

*2025-08-04, version 1.0*

You what if I want Devon on my home page I would move there. I want to be able to put my own home location. For that mistake Im deleting the app!!! Devon!!!!!

### 1/5 — Inaccurate 👎🏼👎🏼👎🏼

*2025-07-25, version 1.0*

100% of the time it is inaccurate. Says it will be clear and always cloudy.

### 5/5 — Most accurate weather app

*2025-06-17*

I look at 3 weather apps every morning and find this one is the most accurate. There may be others that pull from Meteosource Weather API. I like the clunky GUI. All the information is present. Thanks for the app!

### 5/5 — Pretty Good So Far

*2025-05-31, version 1.0*

I was trying to plan an astrophotography session and got 4 different weather forecasts from 4 different services so I tried this app. It was accurate as it turned out, along with only one weather forecast. This app is also recommended by professional photographers online.

### 4/5 — Works

*2025-05-08, version 1.0*

But need slight refinement app forgets the moon or doesn’t show the is
App has potential but lacks good reporting and standard features

### 1/5 — Location doesn’t work

*2025-04-19, version 1.0*

Unfortunately I cannot choose any location rendering it useless, shame as it’s very helpful otherwise

### 2/5 — The moon

*2025-04-06, version 1.0*

Have you forgotten the moon at my location (33947) it’s out and above me but the the app says no moon tonight and how come the home button is not my location???
App has potential but lacks good reporting and standard features
