As time goes on, smartphone apps are getting increasingly complex. There are apps that control your thermostat when you’re on the train, apps that help you edit video - Google’s even developed an app that drives your car.
Sometimes, though, simplicity is the best thing: the new craze on the app block is ‘Yo’, an app that lets you send a message to your friends saying, er, ‘Yo’.
That’s literally it.
The app bills itself as a ‘zero-character communication tool’, allowing its users to tell their friends, basically, that they’re thinking of them.
It’s taking simplicity to the extreme, but apparently it’s doing well: the app already has 50,000 users who have sent 4 million Yos. It has also raised $1m in funding, and is hiring - which suggests it might be planning to expand. To ‘hey’, perhaps? Or, to appeal to the British market - 'alright?'.
