Clinician Testimonials
Dr Mark L. Levy
GINA Board Member and GP with a special interest in Asthma
“Electronic monitoring can be used for early identification and monitoring resolution of asthma attacks. Now, asthma attacks, do not usually occur suddenly, and so an electronic system for warning patients of impending attacks can be very helpful.”
Dr. Andras Szantho
Director of Allergology, Hungary
“Smart Peak Flow measures your peak flow, but also a percentage compared to your last best blow. This comparison is invaluable when trying to work out if your asthma is worsening or not.”
Professor Krzysztof Buczylko
Director of Allergology, Poland
“I recommend Smart Peak Flow as regular peak flow readings help me assess my patients. I know whether the medications I prescribe actually work.”
Dr. Tuck-Kay Loke
Consultant Respiratory Physician at Maidstone and Tunbridge Wells NHS Trust
“The fact I am able to have access to patients’ recordings at this time of coronavirus is particularly useful as I am not able to have many face to face consultations at the present time.”
Sarah Hull
BMedical, Distributor in Australia
“The most common feedback from clinicians is that it empowers patients to take control and manage their asthma. No more excuses at appointments that they forgot their paper charts, as all the data is on their smartphone.”
Debbie Duncan
Queen's Nurse and Lecturer at the School of Nursing & Midwifery at Queen's University Belfast
“Many patients that I have looked after in practice are anxious that their rescue inhalers will run out. Smart Asthma/Smart Rescue utilises technology to support patients in the self-management of their condition. Our patients feel in control again.”
Bev Bostock
Asthma Lead, Association of Respiratory Nurse Specialists
As a clinician and the asthma lead for the Association of Respiratory Nurse Specialists, I welcome any intervention which potentially improves adherence and gives people living with asthma access to tools which support effective self-management. The Smart Asthma/Rescue tools add to the armoury of approaches we can use, both pharmacological ad-nd non-pharmacological, to optimise outcomes in different ways.
Dr Prasad Nagakumar
Consultant Respiratory Paediatrician at Birmingham Children's Hospital
‘We have been using the Smart Asthma devices for our patients in primary care for the last few months. Our patients have found them incredibly useful in managing their conditions and giving them more control over how to manage their Asthma. It’s also helped us monitor in real time the patients’ control of their conditions and alerts us to which patients are not optimally controlled. We can also track their salbutamol use and this helps with stepping up or down their treatment. An absolute must for any healthcare provider dealing with patients with Asthma.”
Rt Hon Elizabeth Truss MP
International Trade Secretary in the UK Government.
Smart Asthma was launched in India in February 2021, during the visit of the Secretary of State for International Trade, the Right Honourable Liz Truss, who commented, ‘’What started as an idea in Imperial College London became a smash hit online, hitting 113% of its crowdfunding target, and is now in demand across the world. I am glad to see it has attracted the interest of the All India Institute of Medical Sciences (AIIMS), whose director Dr Randeep Guleria has been a leading light here in India in the fight against coronavirus. Today’s deal will help secure exports worth several million pounds for Smart Respiratory. It shows what British innovators can achieve and what natural partners they can find in India.’’
Astra Zeneca
Partner in Japan
‘Smart Respiratory offers innovative solutions that bring new benefits to both asthmatic patients and clinicians.”
Lord David Prior
Chairman of NHS England
Lord Prior, Chair of the NHS stated, ‘’Very affordable digital health solution to a problem affecting asthmatics worldwide, using British technology and Artificial Intelligence. Excellent lung function monitoring for people with respiratory conditions.’’
Dr Zainab Awan
Paediatric Consultant - Imperial College Healthcare
‘’Smart Asthma Virtual Care gives me more confidence to make clinical decisions as it provides reliable data. Better monitoring leads to tighter control.’’
Darshan Negandhi
NHS Clinical and Community Pharmacist
‘’At a local pharmacy in south-west London, we weighed returned ‘empty’ inhalers and were astonished. Many were still half full or beyond empty. The Smart dongle helps monitor usage, improving asthma control, saving money and reducing environmental waste, whilst protecting lung health.’’
Aoife Folliard
Respiratory Advanced Nurse Practitioner - Mayo University Hospital (Ireland)
‘’Since the employment of electronic peak flow meters in MUH, we have used the data to aid clinical decision making.’’ From an Irish Thoracic Society poster entitled ‘Accessibility, Usability and Utility of an app-based Digital Asthma Diary.’
Dr Will Carroll
Paediatric Consultant - University Hospitals North Midlands
‘’The Usability and the benefits warrant health economic testing on a larger-scale roll out.’’ From a KJP Poster entitled ‘Reducing pMDI Risks with an Electronic Monitor’ to test if the Smart Rescue electronic MDI monitor mitigates pMDI risks.

Patient Testimonials
“Fantastic app and technology. I track my peak expiratory flow morning and night. It shows if I may be at risk of an asthma attack. I love that I can just email my results to my Dr straight from the app.”
“I love this app it has been a really big help for me, it has helped me see if my inhalers are helping my asthma it’s so easy to use, just plug it in and blow and it gives you a result, I really love it I’ve got my asthma review soon so I’ll be taking my log along with me. Thanks for such a great app.”
“This is absolutely brilliant! It’s such a game changer & so much easier carrying around a smart peak flow as opposed to a big normal one so to speak! I have severe asthma so need to keep everything near ALWAYS!This app has been brilliant & is spot on accurate,my only regret? That i didn’t know about this sooner!! Thank you so much!”
“I love this, it gives a very accurate reading. Great to show my asthma nurse when I next see her. Couldn’t live without mine now”
“This little device is a big improvement on the dumb devices you are usually given. Firstly it records all the measurements so you can easily see from the app whether the trend is up or down. It is also more accurate. I compared my smart peak flow readings with professional readings from the hospital and they were pretty close whereas the mechanical meter I’d got from the doctors was way out.”
“The app works very smoothly and logs my peakflow very efficiently and easy for me and my asthma nurse and gp to see clearly. I’m very happy with the results I’m getting from using the Smart Peak Flow daily, and have even started recommending it to other friends and family who suffer with asthma too :)”
“This is such a great product. I found myself keeping my asthma much more under control with my phone.”
“All ways hated and forgot to chart my asthma, controlling my asthma was non existent until this clever device and app!!! THANK YOU!!”
“Love it.. I can tell if I’m using my inhaler correctly.. I’m finding it so much easier to look after my asthma.. My son is also using it too.. Its brilliant. I would definitely recommend that everyone one has this for their asthma.”
“Easy to set up, easy to use and really helps with controlling my asthma. Its a must have, would not be without my Smart Meter now. Well done on a fab item Smart Peak Flow xxx”
