Thought it might be a good idea to have a thread where people put APPS that are working on Crystalsky.
To Start Airdata, Ugcs & Pix4d

We have replied in your another post.
Since CrystalSky runs Android system and we don't suggest Google service framework at the moment, any APP in Google Play cannot be installed.
Other APP is fine.

Lightroom CC mobile, Snapseed, Litchi, RawDroid Pro, and Canon Connect are working on my CS.  Litchi does work but frequent pop-up message "Google play services has stopped" does get annoying.

pix4d works as of right now. i have it on a 5.5
