applications – Uninstall Android app from Google Play website

I have installed one of the android apps, which is for double tap to screen on/off, but this app is misleading. Unfortunately I gave admin permission for this app, after installing this android app, My mobile screen is never showing up. But, I can hear phone rings, message tones, and everything working fine. How do I make my screen visible now??

Is there anyway to uninstall that particular app, from any website?? I’m pretty sure that, screen is not popping up because of this app. Please help me here.
