mappiness maps happiness across space in the UK. It's part of a research project at the London School of Economics. We'd love to have you on board!

*** NOTE: If you're not in the UK, please see for an important message about time zones ***


- You download the app, open it, and sign up

- We beep you once (or more) a day to ask how you're feeling, and a few basic things to control for: who you're with, where you are, what you're doing (if you're outdoors, you can also take a photo)

- The data gets sent back — anonymously and securely — to our data store, along with your approximate location from the iPhone's GPS, and a noise-level measure


- Interesting information about your own happiness, which is charted inside the app and available for private download — including when, where and with whom you're happiest

- The warm glow of helping increase the sum of human knowledge


- We're particularly interested in how people's happiness is affected by their local environment — air pollution, noise, green spaces, and so on — which the data from mappiness will be absolutely great for investigating

- We hope to have some results published in academic journals, and elsewhere — whatever we produce will be linked from our website,

Customer Reviews


I love the app, I just wish I could measure my happiness over the few months I've been using the app instead of the previous week. I'd like to see if my happiness is improving over the months.
