Niantic, the maker of the game, has now released a wearable, which issues alerts about any events in the game, including the appearance of a Pokémon or nearby PokéStop.
Since its launch in July, Pokemon Go has had keen gamers around the world rushing to catch 'em all.
Niantic, the maker of the game, has now released a $35 wearable (NZ$48), which issues alerts about any events in the game, including the appearance of a Pokémon or nearby PokéStop.
While the wearable is technically on sale, stock levels have already plummeted, meaning potential buyers won't be able to get their hands on one until next month.
Pokémon Go Plus aims to help players catch 'em all without taking out their phone, and was revealed in July at the annual E3 Expo.
Although it was originally slated to launch with the game in July, the small wearable device has only just gone on sale.
But users hoping to get their hands on one will have to wait even longer, as Nintendo's official UK store states that the wearable is 'due to dispatch in late October' and is limited to one per customer.
Over on Amazon, the expected delivery date for the device is '28 Sep - 18 Oct', but is much more expensive, at $109 (NZ$149) .
The wristband gadget - a tear-shaped Poké Ball - can connect to iOS or Android devices via Bluetooth, and will issue alerts about any events in the game.
When this happens, it will vibrate and flash LED lights so that players can throw a ball and catch the Pokémon, by pressing the button in the centre.
But, players can only use the wristband to throw a Poké Ball at a creature they've caught before.
While it may come in handy if a Doduo or a Pidgey pops up, users will still have to take out their phone if that long sought-after Gyarados ever appears.
When the Pokémon has been successfully caught, the device will vibrate and flash to let you know.
A Niantic spokesperson told The Metro: 'We've been testing it here at Niantic and we love the way it allows you to blend Pokémon Go even more seamlessly into family and fitness activities.
'Now you'll be able to play and enjoy your walk, run, hike, park trips or visits to the library without having to look at your screen all the time.
'As you pass by a PokéStop, Pokémon Go Plus will vibrate and light up and alert you to the location. You'll even be able to collect new items just by clicking the Pokémon GO Plus.
'If there's nearby Pokémon hiding in your area you'll be alerted with lights and vibrations; catch the Pokémon with a button on Pokémon Go Plus and then continue on your way.'
HOW IT WORKS
The Bluetooth device, Go Plus, will issue alerts about any events in the game, including the appearance of a Pokémon.
