Running around in the real world for Pokemon can get pretty tiresome, and sometimes even futile if you live in a rural area. Because of this, third-party websites that help players locate Pokemon have become very commonly used, even though the use of them is frowned upon by Niantic. I won’t tell if you don’t though.
Anyway, GymHuntr is a fan-made site that pinpoints all the gyms, and raids in your vicinity. Why is this news you ask? Well, with the recent introduction of legendary Pokemon into Pokemon Go, GymHuntr has made some adjustments to their website. If you load up the site, you can click on any gym or active raid around you, and it will provide you with detailed information about it such as the boss, CP, raid level, and current time remaining.
This means that you can locate and travel to the legendary raids near you without having to spend countless hours going from gym to gym. Thank me later.
