How Flow works

When you experience depression, there are lower levels of activity in the front area of your brain. This is the part responsible for regulating mood, sleep and motivation.

Your brain runs on electricity; Flow sends gentle electrical impulses into the area that has slowed down. This gets cells firing again and reduces your symptoms of depression.

The technology is called tDCS - or transcranial Direct Current Stimulation.

Until now it was expensive and only available at clinics. With Flow you can access the treatment at home.

"Flow is a lifeline" - what our users say


I was driving home tonight and this thought came into my head. I feel alive! Flow is doing something good for me.




Meds were making me numb. Since doing Flow, I have the sparkle back. My partner noticed how different I was. I am loving life.




I'm beginning to feel a lot, lot better after every session. I'm cutting down on the antidepressants, my mind is less fuzzy and I can think straighter.




I was going through a divorce and finding things very challenging. Flow gave me more energy, my brain felt more healthy... it helped me through a dark patch.




Since using Flow I have felt a vast difference in my energy. I am happier than I have been for a long time.




My life was falling apart around me. I couldn't have anticipated how much better Flow made me. I will always have to work at staying well, but Flow has given me a reliable tool.




The major benefits for me are that I feel more resilient and able to cope.




My psychiatrist read about Flow and had good things to say. It gave me the confidence to use the device.




I went on a three hour walk yesterday, which is unheard of me. It's helped me get out the rut.




After 3 weeks I had become more positive, my head was clearer. I felt less cluttered, more relaxed, and anxious thoughts decreased.


Bracknell, Berkshire


I feel so much calmer and more focused after using it.




After 2-3 weeks, I felt more positive and less pessimistic already




Dr Azhar Zafar uses Flow with his patients

Dr Azhar is leading an NHS pilot to see if GPs can integrate Flow into their current workflows:

“Flow has received overwhelmingly positive feedback from our patients, who have reported improvements in their emotional well-being, increased energy levels, and overall functioning. Patients experience minimal discomfort or side effects during its use. Some patients have come off their antidepressants as a result of using Flow."

We use an industry recognised quiz called MADRS-s to give you an indication of your depression severity.

Although the quiz cannot diagnose (only a doctor can do that), a score of over 12 indicates depression.

To complete the quiz, choose the statement that best represents how you've been feeling over the past 3 days.

Most people feel better after 3 weeks. In our data we see another increase after 6 weeks, and again at 10 weeks. Though this does differ from person to person.

One things for sure - you need to follow the treatment plan, which means using the headset 5 times a week for the first 3 weeks, followed by twice a week after that. Each session is 30 minutes long.

Yes. The Flow device was designed by experts and is based on tDCS techniques that have been used in clinics for over a decade to treat depression. The Flow device has undergone research that confirms it is a safe and effective treatment for depression.

tDCS is also listed as a treatment for depression on the NHS website.

Yes. About half of our users follow the behavioural therapy courses in the app, but you don't have to. You can listen to music, watch TV, play computer games - whatever you want. Just don't operate heavy machinery, go near water or perform intense exercise.

Whenever works best for you. Some people feel energised after a stimulation so use it in the morning. Some people feel sleepy so do it at night.

Scientifically, it doesn't matter, so you can work out a routine that works for you.

Yes - Flow is perfectly safe to use with antidepressants, and many people use it alongside medication. If you are thinking about lowering your dose of antidepressants, or coming off them completely, you should talk to your Doctor first.

Flow has been tested on depression. We don't have any specific clinical research on how it impacts anxiety on its own.

However, every week people who use Flow answer a questionnaire. In this sample of 10,000 users 58% are less anxious after using Flow for 3 weeks.

We recommend talking to your Doctor if you're considering using Flow for a stand-alone diagnosis of anxiety.

  • Pregnancy (or suspected pregnancy)
  • Bipolar disorder (or having a history of hypomanic/manic episodes)
  • Epilepsy (or having a history of seizures)
