Bespoke apps for brilliant real-time research


We specialise in creating real-time data-collection apps for academic and commercial research using the experience sampling method (ESM) and ecological momentary assessment (EMA)
  • Mappiness

    Mappiness measures how people's emotions are affected by their environment — air pollution, noise, weather, green spaces, blue spaces and so on. You also learn about how your happiness is affect by the time of day, by who you are with and what you are doing.

    "Mappiness is fantastic"

  • Qwantify

    Qwantify is a research project that investigates the relationship between desire and happiness. You can learn how desires affect your mood, stress, and well-being. Understanding the pull of wants might help make life a bit better.

  • Wesense

    WeSense helps create cities that are more attractive, healthier, equitable and safer. Piloting in Amsterdam, the goal is to learn more about your perception of urban environments and what effects these surroundings have on you. On, the latest data will be publicly displayed.

  • moo-Q

    moo-Q investigates the relationship between mood and brainpower. The app records your positive and negative affect, your memory ability and processing speed. You can learn more about when your brain works most effectively and train your brain’s working memory capacity and processing speed.

  • EmoTrak

    EmoTrak is an app developed in partnership with Eve Ekman from UCSF that asks daily questions about your experience of emotion. This form of ecological momentary assessment (EMA) has been found to be successful at promoting awareness and behavior change. It helps develop mindfulness of emotions and self reflection so users can more skillfully navigate their individual and interpersonal interactions.


Go Real-time

The experience sampling method (ESM) is the new gold standard in data collection

Using ESM, study participants are asked brief questions about the here-and-now, on regular but randomly sampled occasions. Responses are aggregated over time to provide a wealth of data. ESM was first applied in the 1970’s using beepers and paper diaries. PSYT has reimagined ESM for the smartphone era, making it simple to collect rich, accurate data from very large samples. 


Uncover rich within-person variation that is undetectable by traditional methods



Gain ecological validity by surveying people as they go about their normal routines


Ask more questions and control for a greater range of confounding variables while avoiding study fatigue


Avoid cognitive biases and heuristics that plague retrospective self-report surveys

Our platform allows you to capture data from multiple sources, deliver interventions and view data in real time

Gather data from multiple sources

We create native iPhone and Android apps that can capture:

  • Audio/Image
  • Self report data
  • Cognitive assesment
  • GPS
  • Heart rate
  • Accelerometer data

If you have an idea for a digital intervention we can help you design it, develop it and assess its efficacy. We can integrate audio, video and gamification techniques to maximise user engagement.

Visualise data in

We can provide you with custom dashboards for real-time visualisation and tracking of variables.

  • I came to PSYT because of their experience in applying cutting-edge technology to psychological data collection. Experience Sampling has many advantages over typical methods. They asked all the right questions, and delivered an app that was better than we could have hoped for, quickly and within budget. The app attract a huge amount of media attention and we had tens of thousands of research subjects in just a few weeks. Now we're getting to work with a wealth of high-quality experience sampling data that provides remarkable insights far beyond that which could be obtained from typical survey techniques. I can highly recommend working with PSYT.

  • PSYT worked closely with us to realize our ideal mobile research tool. Their expertise in psychology, measurement and mobile apps made them our perfect technology partners. They’ve been incredibly responsive to all of our needs throughout the app development process, and have gone above and beyond in terms of service. Users love how the app feeds back analysis of their own response data, and we love how easy it is to access, analyze and gain insights from the data as it comes in. They are truly wonderful to work with!
