If you want to do more than just take random pretty pictures of stars, nebulae and galaxies with the S50, here are a few apps and programs that can help. Most but not all of them are free.
I cannot recommend this app enough, and on top of everything, it is free. It is called Astrospheric, search for it in Android and Apple appstores. It will give you hourly forecasts a few days in advance for your location. I mean astrophotographic, not meteorological forecasts. It is a bit daunting at first but you will get used to it, I use it all the time to plan my nightly observation sessions and it is a huge timesaver.
Stellarium, this is not free, but it is worth the money in my opinion, there is a 7-day eval mode, then either a monthly plan or a lifetime license, both of them quite affordable. It gives you the sky down to magnitude 22 stars if you want that, at any point in time, past or future. In my opinion, this is what SkyAtlas should be, but rather than putting a lot of development effort into that, I think ZWO should partner with whoever wrote this app as this is a symbiotic relationship and both parties could benefit greatly from it. Stellarium even has a GoTo feature to control a telescope, exactly like SkyAtlas, it is just a simple matter of adding the S50 to the list of supported telescopes. It is so cheap but useful ZWO could include a license with every S50 if they get them in bulk. I check the weather in advance with Astrospheric, then plan my sessions in Stellarium and only use SkyAtlas to start and stop the acquisition. If the Stellarium could control the S50, you would not need SkyAtlas at all, as it is orders of magnitude better. The only merit SkyAtlas has is tight integration with the S50, but that's all.
If you are worried about your privacy (you should be), you need to know that sharing the *.fit files produced by the SeeStar app will reveal the GPS location of the place where the picture was taken. It's not super precise, about 50 meters or so, but if you want to keep the location private, do not share *.fit files as they are. Sharing *.jpg files is OK from a privacy point of view. There is a free Windows and MacOS utility called ExifTool written by Phil Harvey, which you can get from https://exiftool.org/ - it will reveal all the metadata embedded in the *.fit files, a lot of very useful information, by the way. The two fields of concern from a privacy point of view are called Sitelong and Sitelat. I have not checked that but I think ExifTool will let you even remove the GPS fields from the FITS files, if you want to share them without GPS information. The GPS information is useful to have but not really required unless you do some automated/distributed/remote access kind of acquisition project with multiple S50s and you need to know where each one is located. As a single user you already know your GPS coordinates or you can get them from GoogleMaps with better precision than the S50 so there is no real need to share this data. This is a security hole and it should be plugged ASAP.
I strongly suggest ZWO to turn off including the GPS info into the *.fit files by default, it should be an "opt-in", not an "opt-out" feature and it can expose them to liability issues - you do not want to get the lawyers involved. Or the Europe GDPR people. Including GPS data into the FITS files should be off by default, with an option for the user to turn that on, accompanied by a disclosure with strong warnings that doing so and then sharing the FITS files will reveal your exact geographic location. If I were ZWO I would put this as priority number one on the to do list, on top of any features we keep asking for here.
