Its definitely the original, legitimate Tamagotchi experience, but it hasnt aged well. The apps push notifications help keep track of the Tamagotchis stats, but only when they work. I didnt get any notifications all day one time and I came back to find it died. Ive gone through three pets that died because of this, after which I found it to be enough.
