app help/ question

Good evening,

I'll start off with some small background, theres a browser game I play where ever 1million total kills across all players we get double XP for an hour. the total current kills are shown on the homepage.

Im wondering if there would be a way to make a small app that essentially notifies me when the game starts getting close to the one million kill mark.

Since it is a browser based game I was thinking the app could open the browser grab the piece of code that shows the current kills checks the last 6 digits, and sends you a small notification via sound vibrate or LED every 50k kills after 750k.

Essentially id want it to be an app capable of running in the background or as a widget.

Since this is for very small use maybe 100 users tops I was planning on using googls app inventor to make the app and titanium backup to distribute the APK.
