It might be from the developers behind the popular to-do app Clear, but Hatch is the antithesis of a productivity app. It's an attention-sapping reimagining of Tamagotchi and the countless other virtual pets that were all the rage in the late '90s. And it's adorable.
As someone who queued for the first Tamagotchi release in the UK back in 1997, I'm a sucker for things like this. If you need me, I'll be feeding my Fugu.
