You don't need anything more than your smartphone to play Pokemon Go, but for the Pokefan looking to get some extra fun out of that game and a Pokemon app coming out later this year, the Pokemon Go Plus+ should be on your radar. The Pokemon Go Plus+ is available to preorder now for $55 at Amazon and Best Buy ahead of the gadget's July 14 release. The Nintendo Store has been sold out for months, so we wouldn't be surprised to see other retailers sell out, too.

A link between the Pokemon Sleep and Pokemon Go apps, this compact accessory acts as both a lullaby machine and an alarm clock. Simply press and hold the center button doww, place it next to your head, and you'll get Pikachu to sing you to sleep and wake you up with a cheerful prompt. Pikachu grows friendlier the more you sleep, unlocking more sounds along the way, and you can even collect more Pokemon during your sleeping hours to help complete the sleep Pokedex.
