“Good price, however I took a risk as my phone was not listed. I have a Samsung S10 plus which has an earphone jack socket. The app was not in the Google play store, but I managed to find the app apk to download on the Skywatch Windoo website. I installed it on my phone, plugged in the Windoo and it worked! (I couldn't connect to the Windoo server to access the windoo map which may no longer be running, but that is not needed for the functionality). Nice little compact anemometer and temperature tool.”
