You're probably already fed up of your sore feet caused by playing Pokémon GO and searching for a Blastoise. Luckily enough you can download radars for this game to locate your Pokémons on a map so that you don't have to make so much effort. We don't want you to go over the top on the exercise.
Pokémon GO radar for Android
It works similarly to other maps and radars that you've already tried out: in PokeFast you can search on the map and scan your area, using your GPS, or any other place in the world (in case you use an app similar to Fly GPS to spoof your location). Once you find the place of your choice, press the scan button and check out the area.
Articuno is going to be easy to find with this radar.
One of the interesting functions you'll be able to make use of once you download the APK of the application is the possibility to memorize locations: you can keep a record of locations of your interest and visit them whenever you want.
