This app was recommended by a friend. Not really into 'sharing' a lot on socials, I was a bit sceptic at first. But, I have to say, I am surprised how nice it has implemented the science of happiness into an app. Both the ability to share with random people who change every view days 'Cafe', as well as having the posibility to create groups is nice. It adds a nice dose of positivity to every day! No data mining, no advertising. Just a lot of shares of joy and gratitude. The app is available for both Iphone and Android, so feel free to give it a try!
