There are real-time Pokemon Go trackers that are still online and actually get faster and better.
There are still Pokemon Go trainers that miss PokeVision. The popular Pokemon map had millions of users when Niantic shut it down through a combination of legal and technical measures end of July. A lot has changed since then. Niantic started to protect its infrastructure with a digital signature that prevented 3rd party tools to connect and scrap the Pokemon location data.

Update 08/23/16: The new Pokemon Go app updates introduce new security features that will make FastPokeMap and other 3rd party software stop working. The developer behind FastPokeMap is not sure if there will be a fix to bring back his service.
That measure was cracked in a matter of days. Now weeks later, Pokemon real-time maps like FastPokeMap are providing real-time Pokemon spawn data directly from Niantic's servers. Not only is FastPokeMap offering to spot nearby Pokemon, but also offers the data through an API to other 3rd party tools. The PokeDetect app for instance is using the FastPokeMap API.
The developer behind FastPokeMap is not in it for the money. He actually doing it at a loss. He said in a recent post: "I am working as a security researcher and I'm doing all this mostly alone on my own free time with a LOSS. I'm not making any profit. Donations and ads money aren't enough. I don't care. I want to please you guys to make sure you can enjoy the game again. And Niantic made it really hard for me to provide a stable service without spending a shitton of money. But you know what? Screw it. I'll do it anyway. Because the "customer" (or in this case the player) is always king."
This guy is a nightmare for Niantic. He is like the Robin Hood of real-time Pokemon trackers. If the location of the Twitter account of FastPokeMap is legit, the programmer behind FastPokeMap is located in South Africa. It might be difficult for Niantic to get a legal handle on this one, but then should they even act? He makes it sound that as soon as Niantic provides proper way to find Pokemon in the app, his mission is over.
FastPokeMap is indeed fast, but has limited radius. The developer explains the smaller radius in FastPokeMap versus the one trainers had available in PokeVision through the many technical changes Niantic introduced. Besides digital signature there are also account limits per IP and more. Find a detailed explanation in this post.
Important: The use of any 3rd party Pokemon Go app can get your account permanently banned.
