The fact I could not stay on the computer and refresh my browser every minute waiting for a specific topic or product. it was hard for me be the first one to reply to a clasified posting or reply to a conversation. That is why alertivity was created. It will alert me via email/push notification even if I am not infront of a computer whenever something specific that gets and meets my keyword filters posted on a website so I can take action on it and beat everyone else to the seller. It basically filters out the noise and only gives you access to the good stuff. I hope you all find our service useful.
