I created an Upvote notification application that you guys can use.
It's still in development and I am planning to add a few more featuer.
At the moment you can track Upvotes on your streams DLive post.
When the post receives an upvote a notification will be played.
There is a default notification but you can use any other ".mp3" file.
In the video you can see a basic tutorial of how to set it all up but it shouldn't be difficult.
Open "index.html" with Chrome or Firefox.
Enter your username and the permalink of your streams Steemit post.
Press "Start Tracking!".
To use a custom notification place a new ".mp3" file in the folder of the notifier and name it "notification.mp3" .
The volume of the notification can be adjusted within the tool.
You can download the tool here:
