Sickweather has also been honored among "100 Brilliant Companies" by Entrepreneur Magazine, "Top 5 Sites Crowdsourcing for Your Health" by George Washington University School of Public Health & Health Services, and has been recognized for identifying the peak week of flu season 15 weeks before the Centers for Disease Control & Prevention (CDC).

Sickweather uses a patent-pending process to track and map reports of illness from social media in addition to crowdsourcing directly from our user community.

Our SickScore calculates the risk of contagious illness in your immediate area, meanwhile reports are represented on the maps by blue "SICK" markers -- tap them for more information of exactly when they were reported. Some viruses can survive on surfaces for up to 48 hours and can have a viral life cycle of 2 weeks, so we color-code more recent reports as RED within 1 day, ORANGE within 2 days, YELLOW within 1 week, and we include reports as old as 2 weeks in BLUE.

With Sickweather Groups you can follow, report illnesses, and post messages directly to the locations that matter most to you, such as schools, workplaces, restaurants, hospitals and more!

Unique to our APPLE WATCH app is a hand washing timer which runs for 20 seconds (as recommended by public health organizations) and uses Apple's Taptic Engine to let you know when you are done.

And don't forget to check out our fun STICKERS for iMessage!

Note: Continued use of GPS running in the background can dramatically decrease battery life. Sickweather can be used with or without these services running, but to receive our real-time Sick Zone alerts, location services must be turned on. You can discontinue GPS services by simply turning off our Alerts from within our app settings using the Master Switch.

Good Informational App

I just started using this app to monitor the horrible flu season this year. It looks like they are currently working on updates that will allow you to track individual family member overall health which will be a nice update. The only thing I can see as a limitation is that more people need to actually use the app to get more accurate totals of illnesses in areas.

Cannot use without agreeing to some hefty privacy waiving

Look, I don’t typically get all huffy about all of the electronics tracking us, Alexa listening to us (ok, that’s a little creepy), allowing location data, etc. But this app seems to really take it far, especially considering it involves health data. You really cannot do much on the app without agreeing to location services and creating an account, which includes the disclaimer that your info will be shared with partners for marketing purposes. No thanks.
Without agreeing to all that, all you see is a weird pile of markers- sick reports I guess?- piling up on city hall on a map. You can’t even click individual markers, because they’re literally in a single pile on a single pixel (or whatever). You cannot see a breakdown of WHAT illnesses/allergies/symptoms are being reported. Total waste, looking for a refund.

Developer Response ,

We appreciate your concerns and we do our best to make our service affordable to the general public while still covering our costs. Regarding your last sentence, if you tap your SickScore you can navigate the maps of individual illnesses and symptoms in your area.

I love Sickweather! I tell everyone to download this! Everyone from my apartment building, to my family, to my Facebook friends. It has helped me to keep track of what illness is going around my area to what illnesses are going around my family’s area when I go to visit them. Plus I love that I can let Sickweather know what illness I have to alert others. Although I do miss when they had the “man flu” on here and I wish that they would bring that back. I always had a laugh with that and friends of mine would chuckle at that too.
