Thank you Prof Spector for steering us thru most of Covid'! And I can definitely say its an excellent &amp; easy app for daily use. . The large no. of followers make it a v significant sample....&amp; hope govt scientists give it &amp; the full attention it's due! Prof Spector's personal weekly updates by video are very clear and supportive🤗🤗and reassuring to the nervous! Which I'm not. Great in combination with Dr John Campbell!

Such a quick and simple survey to complete that is so important for our current and future health and wellbeing. If everyone completed this there would be so much data which can be used to ultimately help every one of us.

Jill Henderson

I have found this app an invaluable tool in navigating Covid, particularly important to me as I am immuno suppressant. The information is clear, regular and dependable. It is user friendly and is run by a highly qualified group of specialist health care scientists based at King's College London. It is also now exploring significant developments in gut health and how it affects so many long term life changing conditions such as diabetes, dementia and cancer. I will happily keep logging!

I'm pleased to be able to fill this in &amp; hope it will help the research in some way. It's quick &amp; easy &amp; only takes a few minutes each day. This app has proved itself invaluable to the scientists who have been able to use the 'citizen science ' element to help predict &amp; map Covid hotspots with increasing accuracy. The associated research opportunities presented from it are also invaluable, increasingly so with things like Long Covid &amp; changes in symptoms associated with new variants of Covid!

Maggie Wiscombe

An excellent study. Very easy to use. Makes you aware of symproms and how you're actually feeling each day. Very interesting to keep up with the excellent research which has given me a great deal of support since having Covid. The information has given me reassurance and information to help me through Long Covid. It is brilliant.

Updated review: The app was good when I started using it in 2020. It is now brilliant, with interesting and informative information. I started using it to do my bit to help, but I get so much helpful information in return! In April 2020 I wrote &gt;&gt;&gt; "It feels good to contribute to this research. Takes less than one minute each day."

Simon Carter

Good app helping to amass more data on Covid-19 and it's symptoms. Have recommended it lots! Slightly irritating thing is that reminders to enter my daily update have stopped recently. I keep on trying to switch on notifications but it doesn't work now!

Philip Duncan

I been reporting since the the beginning. The feedback I get is really informative and I believe the data that this app presents is way ahead, both in terms of accuracy and speed is far superior to government reporting.

Excellent app for tracking covid outbreaks in my area. Very easy to add your data and it is a great feeling that you are contributing to the scientific understanding of the pandemic. It is fantastic that they are planning on tracking wider health issues. I highly recommend using and contributing your data to this app.

Annie Buchwald

Super easy and fast to use! You log in and from then on, it pops up every morning with a very quick 2 questions. Every Friday it asks a few extra questions. The whole thing takes between 5-30 seconds and helps researchers. There is no personal information involved.

Marilou Mullan

Daily, easy tracking. Two touches is all it takes. It seems to me that, by this simple, free, technology screening, from the bottom up, we can all assist in something the government, from top down, has been unable to do. Right now, this app shows, in order to get a statistically significant number we need 495 more people in Amador to participate. Please do!

Robbie Goldberg

Extremely easy to use, and can add profiles for other who don't use technology. I've felt helpless in this pandemic and the app makes me feel like I'm contributing. The hospitals sponsoring the app are reputable and it never asks for identifying information so it's trustworthy. It's great to contribute to research for free, and in less than a minute a day!!

App makes me feel I&rsquo;m helping in small way I have encouraged many of my friends and family to use this app and most have. Those who haven&rsquo;t are continuing to work with young children so understandably they are the ones who haven&rsquo;t had time. I forewarned people that there were a few pages of questions initially but then just two questions daily in most cases if no change in health. Having read a previous review it did mention that someone thought they had had virus but wasn&rsquo;t tested. There was nowhere to record possible infection even if not verified. I too believe that I had the symptoms with dry cough and extreme lethargy for weeks and my dog had dry cough for weeks with me too. However this was in January/February before I saw any mention of Covid-19. I have seen others online mention similar symptoms. This may be unrelated but I wonder whether this is something to investigate possibly in the future. That aside I&rsquo;m pleased to help in such a small way. I&rsquo;m doing volunteering work and would like to do as much as I can to help. This app makes me feel better on a national scale.
