I wanted to install Sencha Space on my ASUS Nexus 7, Android Version 4.3 but I could not find it from the Google Playstore app. Whereas I could see it from desktop site http://ift.tt/1K3ec18. When I entered the same URL on my device's browser and tried to install, I was shown a message: "Your device isn't compatible with this version."

What's the issue? Can someone point out the way out?
