Track Your Happiness

By Matt Killingsworth

This app is only available on the App Store for iOS devices.


Track Your Happiness is a scientific research project that investigates what makes life worth living.

Using this app, you’ll be able to track your happiness and find out what factors — for you personally — are associated with greater happiness. You’ll also contribute to our scientific understanding of happiness.

Thinkers from Aristotle to William James have argued that happiness is a core goal of life. Paradoxically, enormous improvements in the conditions human life — bigger houses, more powerful technology, better medical care — have achieved only modest improvements in happiness.

Track Your Happiness aims to use the latest in science and technology to help you better understand the causes of your own happiness, while also contributing to scientific research that could one day benefit everyone.

A few times a day, you’ll get a notification and be asked some questions about your experience at that moment. The idea is that by measuring your experience at many individual moments, you’ll get an accurate picture of your life and the determinants of your happiness.

Let’s get started tracking your happiness!

Great method

Heard about this project through the TED Radio Hour podcast. I think it's a really great start to pinpointing what drives our happiness. I love that it is randomized, convenient, and likely reliable (as a "self improvement" tool, respondents are probably much less likely to answer dishonestly). The only addition I'd like to see is questions about the quality of human interaction, similar to the "productivity" question. For instance, if you recently got in a fight with your spouse, your low happiness score wouldn't be related to the fact that you're with someone, but more specifically related to the fact that you're with someone who you're upset with. The downside to this is it runs the risk of making the surveys too detailed and extensive, but personally, I think my level of happiness is closely related to the quality and status of my relationships. This is a great app though, and I'm really enjoying being a part of it.

Pretty awesome--for the average working adult

I learnt about this app in my psych class; it's a pretty awesome app! It's especially fun to see the correlations between activity and mood become clearer as time goes on and you use the app longer.
One suggestion I'd like to make is to make the question choices more accessible to a variety of people--which is to say, I'm a college student and I find that some questions (esp. the "where are you"? question) are difficult to answer (if I'm at the dining hall, am I at a restaurant? At home? At work? etc.). I'm aware that if you're doing a case study, it's easier to collapse these demographics across the board, but the lives of college students are pretty radically different from adulthood and that might be a confounding factor. Otherwise, I'm having a lot of fun with this app on a micro, personal scale! :)

Love the app, could be better though!

It does seem like this app notifies me pretty often, and since I work and go to school, often I won't be able to answer the questions, maybe leave a text box, under the how long ago we notified you, so we can quickly jot down feelings and the activity or where we are, so when we go back to it we can easily read what we typed earlier. Also I personally think the reports page is confusing -and that it could be better designed. I'm other than I previously said, I really love this app, and what they're trying to do with this app, I highly recommend this to everyone.
