Have you ever wondered if your brain works better when you’re happy?

Or worse when you are sad?

We have! And that’s why we created moo-Q: An app that tracks your mood and your brain’s power.

To see if mood and brain power are coupled, we need your help! Please download moo-Q here, register, choose your settings – and you’re ready to get your first moo-Q!

We promise it will be quick and fun to do moo-Q – each go takes only 2 minutes tops!

 The moo-Q app was developed by the fantastic PSYT team, who specialise in psychological measurement techniques and interventions.


moo-Q has gone global

When we released moo-Q on the Apple store in the summer of 2015, we were hopeful that it would be downloaded a few thousand times and worked hard promoting to everyone we knew. They all seemed to like the app as much as we did, because it was picked up by media outlets around the world and to date has been downloaded more than 25,000 times in 158 countries. The graph below shows you the countries where it’s been the most popular and that we have about twice as many men as women using it.

Your user stats explained

The main screen stats gives you an overview of the alerts that you have completed, your response rate and the time that you typically take to respond to an alert.

Abby FrequencyAlerts completed is the total number of alerts that you have received so far and responded to. However, this excludes times when you have completed the app without receiving an alert.

Response rate indicates how many alterts you have received and respinded to. You should try to keep this number high, because a low number means that you’ve missed many of your moo-Q alerts! If you do not respond to an alert and receive another one, you will only be able to respond to the most recent alert.

Typical response time is how much time it takes you on average to respond to an alert. One or two minutes are an excellent average response times.

Your user feedback explained

Complete a minimum of 5 alerts, and you can unlock your moo-Q chart that shows your mood & cognitive performance in terms of:

Sophie DaysPositive affect refers to experiencing positive emotions. When you are high on positive affect, you feel enthusiastic, energetic, confident, active and alert.

Negative affect describes low mood that goes hand in hand with experiencing distress, anxiety and even anger. Luckily, negative affect states don’t last for long and are often situation-dependent.

Short-term memory is a limited storage capacity in your brain that holds information for 20 to 30 seconds. The information is then either forgotten or passed on to your long-term memory stores, where it may remain indefinitely.

Processing speed is a measure of your cognitive efficiency. It involves the ability to automatically perform relatively easy tasks – it’s quite similar to the horsepower of a car, just for the brain!

Working memory holds and processes information that you already hold in your short-term memory and new information input. In other words, it’s the ability to continuously do mental operations: specifially, the ability to be working your memory.


I have a different question2017-05-26T13:36:46+00:00

If you have any other questions, please send your message to and one of our team will be in touch.

What if I’m abroad?2017-05-26T13:36:07+00:00

Our app uses a tiny amount of your data, no more than sending an e-mail for example (around 1KB). So If you have a small data bundle of 100MB per month, moo-Q should use less than 1% of it.

What if I’m abroad?2017-05-26T13:35:23+00:00

If you travel abroad you will still receive alerts (also, we will be a bit jealous of you). Please ensure that you set your device’s time and time zone correctly, or notifications may be sent at the wrong times (such as when you are asleep).

What are the main screen stats?2017-05-26T13:34:47+00:00

The main screen stats consist of the number of responses you give, your response rate and the typical response time. Those describe the quality of your responses and if they can be used for our research. You can help us with this by responding to every alert as soon as possible. This is important because when you respond later or not at all, it might be systematically different from when you respond soon after the alert. The stats help you keep track of your responses:

Alerts completed is the total number of responses you have given when you were alerted. However, this excludes times when you have completed tasks without receiving an alert.

Response rate is the frequency of times that you responded after receiving an alert. You help us by keeping this number high! Please note that if you do not respond to an alert and receive another one, you can only respond to the most recent alert.

Typical response time: here the app counts how much time it takes you on average to open the app in response to an alert. 1-2 Minutes is an excellent average response time.

Is it secure?2017-05-26T13:33:02+00:00

Using this app is secure, because all communication between this app and our data store is over a TLS-encrypted connection – the same kind that is used for online banking and shopping. Also, access to the data store is only over a secure connection.

Is the app anonymous?2017-05-26T13:32:21+00:00

Yes, it is anonymous. We do not ask you for your name, phone number, e-mail address or any other identifying information.

What will you do with the data? Is it confidential?2017-05-26T13:03:17+00:00

We will analyze the data to find out how mood and brain power are related. This data collection is part of an academic research project funded by the British Academy and Goldsmiths University of London. If we find something interesting, we will try to publish our findings in a scientific journal. Your data will always be kept confidential. Reports or publications based on the research done with this app will only use group data and not identify any individuals affiliated with this project.

What data will I be sharing?2017-05-26T13:02:13+00:00

moo-Q will record the answers you enter each time you use the app. The answers – mainly to the mood and brain power questions – will be sent to a secure data deposit, to which only researchers involved in this project have access. No other data from your phone will be accessed or transmitted.

How long will it take?2017-05-26T13:01:18+00:00

Completing the app will take 2 to 3 minutes each time. Registering for the app will take another minute or so but you will only do that once. You use the app as often and for as long as you like (we’d like you to take part for forever!)

What will I be asked to do?2017-05-26T12:59:48+00:00

After registering with moo-Q, you will answer some basic demographic questions. Also, you will choose the times during the day that you want receive alerts from moo-Q – after all we don’t want to wake you up on a Sunday morning if you don’t want to – and how often you want to be notified per day. moo-Q will send its alerts accordingly.

The moo-Q alerts will prompt you to open the app and complete mood ratings and three short tasks in a safe environment (so not when you’re in the middle of the birthday party and about to dig into that delicious cake). You will then be asked to answer a few brief questions about your surroundings and activities you’ve done on the day.

When you have completed the app five times, you will be able to access charts of your personal mood and brain power over time. With that you can see when you were in the best mood and had the greatest brain power!
You can also complete moo-Q any time you feel like it. You don’t have to wait for an alert to prompt you but moo-Q will send them to remind you to complete the app. You can change or switch off the moo-Q alerts in the app settings.

What is this research for?2017-05-26T12:58:14+00:00

We want to know how mood influences our cognitive performance. It is possible that our brains work better when we are happy and relaxed and worse when we are upset and distressed. But the opposite may also be the case: being a little happy may make our brains work harder to overcome the situation and move on. Can you help us find out what the process is?
