What is Long Covid?

Long Covid is a term used to encompass the ongoing symptoms and side effects still felt by an individual after they have had Covid-19.

Our app is based on international research identifying almost 200 symptoms.

The most common symptoms include:

  • Fatigue
  • Breathing difficulties
  • Brain fog
  • Loss or altered taste
  • Pins & needles/limb weakness

Take Control,
Make your Data Work for you

If you are suffering from Long Covid symptoms then you are not alone. Many people who have had Covid-19 suffer from related symptoms for many months.

The important thing is to recognize that you are still unwell and to seek professional advice from your doctor to stay safe and to aid your recovery.

The people helping your recovery will greatly benefit from seeing a detailed log of your symptoms so they can provide you with the best advice.

Quick & Easy to Use

Helping you to get the support you need from the health services

Doctors are increasingly using the phone or video conferencing for consultations due to the huge increase in demand for their services. Providing advanced access to your symptoms diary is very helpful both for saving time and providing clinicians with a detailed insight into your medical condition.

It is the future of healthcare.

  • Easily select and score your symptoms from a list.
  • Provide your doctor (or your family) with access to your record so they can see your symptoms.
  • Help to drive your rehabilitation by reporting your progress.

Based on Science and Medical Expertise

We collaborate with leading academics and NHS service providers.

The symptoms listed in CHAI® LongCovidTracker are based on international research into Long Covid.
