My house-share experiment with the Splittable app

Can technology designed to split the cost of shared living beat the old-fashioned Post-it note?

I was on the phone at 10pm on a Tuesday when I learned that I owed my housemate 13.61 towards the water bill. It was the moment I realised this new app had been a huge mistake.

Splittable is a free download to help house-sharers get on top of living costs. The concept is simple: when you buy washing-up liquid or pay for repairs, you put the expense into the app, then everyone knows they need to pay up.
