Pokemon Sleep is a spin-off game for mobile devices namely Android and iOS. Not to fall behind on introducing a new accessory, the Pokemon Go + PLUS will arrive this July. It feels like a remake of the Pokemon Go + but with the addition of the Pokemon Sleep functions.
Personally it feels like it's a remake of the Pokewalker. The humble Pokewalker is a pedometer that you carry or strap with you where curious Pokemon you encounter would "follow" you along the trip. You would first transfer your "lead" mon to the Pokewalker, measure your steps, and then transfer any mons that followed to your box. The Pokewalker and the 3DS system would communicate via the handheld's Infrared. The Pokewalker was such a cool concept. I kept two of which - since I bought Pokemon HeartGold and Soulsilver. It made my commute a little more pleasant and fun back in 2010.

In Pokemon Sleep, you're sort of collecting your hours by keeping track of your sleep and rhythm. And Pokemon Go involved catching Pokemon on your commute (err... journeys) although in a much grander scale. Little did we know that the Pokewalker was the pilot for future accessories. It was a freebie inside a game box. Whether it's worth getting the Pokemon GO Plus Plus (sorry I still can't help laugh) that would be a discussion for another day.
