As a new YouTuber, I am always opening my channel to check how many subscribers are on now, so I thought, why not create a gadget that Is always keeping tracking of how many subscribers I have. I did that, with small software I created. it can sync the subscribers every 1 minute to give you a live feed of how many subscribers in your channel.
