About us

The concept for the device began in 2014 at Imperial College London. Smart Peak Flow was invented to help people keep track of their asthma in a convenient way.

Several prototypes later, the device was put on Kickstarter. It was then 113% funded on Kickstarter.

In 2017, the final device was created and is the world's first peak flow meter to use smartphone technology.

This device is important because, in the past few decades, asthma care has mostly stayed the same. However, the number of mild to severe asthma cases is growing. This device helps those people with their condition by giving accurate information and what they can do to manage it better.

"I will never forget how his tiny chest rose up and down in desperate movements, trying to fill his lungs with air."

Watching your child have an asthma attack can be terrifying and leave you feeling emotionally exhausted and on edge.

Asthma affects over 1 million children in the UK so you are not alone.

Did you know hayfever can make you more likely to have an asthma attack?

When you have hayfever your body is allergic to pollen and releases antihistamine and other chemicals to try and fight it. It also makes your body produce more sticky mucus that can block your airways, which become inflamed.

This means they are more sensitive to other triggers and more likely to swell further, restricting your breathing and causing an asthma attack.

Here are five steps you can take to reduce the risks:

1. Take a daily antihistamine to try and prevent an allergic response
2. Use a barrier balm around your nose to reduce the pollen entering your airways
3. Take your preventer inhaler as prescribed every day
4. Carry your reliever inhaler at all times
5. Measure your peak flow and visit your doctor if it is less than usual
