This is on it’s way to becoming the next popular Pokémon game, but they’re are some minor things I want to point out. First, PokémonSleep doesn’t work without internet, but you can turn off the internet after starting your sleep session, and turn it off before ending your sleep session if your worried about that. When you are on a vacation is somewhere with no signal for more than 30 hours, than you can’t track your sleep. A positive thing to point out is that if you forgot to track your sleep data for one night, then you have 30 hours to recover your sleep data. Second of all, if you forgot to plug in your phone at night, then PokémonSleep uses lots of battery. A lot of sleep apps that I know of only uses 30% battery at night, while PokémonSleep might use that in an hour! If you charge your phone at night, though, then you’ll be fine.
Thirdly, the premium subscription is way too expensive, so think about whether you need it or not before buying it.
Finally, on PokémonSleep Store, this says that this is a simulation game, but this is actually a health and fitness game. I would recommend changing the category to that on PokémonSleep Store. Pokémon sleep is still a great app to use though, if your fine with all of the stuff that I mentioned!
