The WiFi Launcher merely finds the IP No for the GS911 and then launches a web browser, if you look at the settings in it the web browser can either be the tablet/PC inbuilt web browser or one of your choice
Set up the GS911 WiFi so it connects into your home WiFi network, that way you can use any system to access the GS911. Once it is connected you can use the admin utilities of the home WiFi router to reserve an IP No for it and add a bookmark in what ever browser you use
To give an example I needed some real time figures recently, I plugged the GS911 into the bike, configured real time recording from the Linux PC on my desk, went out for the day on the bike and when I returned home it auto connected into the home network and I sat down at my PC with a cup of coffee and retrieved the real time data from the bike. I could also have used the tablet to do the set up and left it in the tank bag
Re "cloud Services" they can be useful in a city/workshop situation but not very useful when out on the road, onboard routines in the GS911 are still needed
