The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements.
The primary use is to show VIIRS/DMSP data in a friendly manner, but over time it also included some other interesting overlays that concern light pollution like SQM/SQC, World Atlas 2015 zenith brightness, clouds, aurora and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail.

I’v been using the website for a long time and it’s great to finally have a more usable version for mobile. Happy to support the developer more directly too and remove the ads. Thanks to the developer for adding landscape mode on iPad after request. 👍 Now wishing for a lighttrends app and the new contribution tool 😉
Developer Response
Thanks for your feedback. The new version should now support landscape mode on iPad.
Great, but wish text was larger.

I really like the app, but I have trouble seeing the text (location names). When i try to zoom, the landscape zooms but the text remains very small. I would love an option to zoom or set the size of the text.
Developer Response
Unfortunately the basemaps are provided by Microsoft and I can't customize them. The good news is that there are high DPI versions of the same maps which have larger labels as you zoom in. I just updated the app to version 1.1.7 which has the option to switch to high DPI basemaps under Settings. Try it out and let me know.Edit: It seems Microsoft just changed how this works (the map is sharper, but text is still small on all zoom levels). A fix will have to wait till the next version
- Feature filters can be now be saved (settings). Name field also supports wildcard searching for example '*town OR john*' will display 'Smalltown' and 'Johnstown'.
- 'My locations' can now be saved (and edited) and restored from a file.
- 'My locations' now also available as a feature overlay, so you can view them on the map.
- Changing dates in the calendar widget doesn't open virtual keyboard anymore (except when you tap on hour/minute fields).
- Other minor changes and bug fixes.
Version 1.1.39
