Reminds you to mask up when you walk in somewhere indoors, when you head out the door, and as you reach the train. Plus COVID, flu and RSV levels near you.
Mask Minder reminds you to put on a mask when you walk in somewhere indoors, when you head out the door, and as you reach the train.
It's made for people who mask on purpose: immunocompromised and COVID-conscious people, long-COVID patients, carers, and anyone who doesn't want to walk into a doctor's office bare-faced.
HOW IT WORKS
• Arrive somewhere indoors and you get a reminder. Mask Minder notices the places you visit, so you don't have to add them by hand.
• Heading out? A nudge to grab a mask a minute or two after you leave home.
• Wastewater levels for COVID, flu and RSV near you, from the CDC and, in and around New York City, from NYC Health. You get an alert when a level rises and when it falls again.
SMART, NOT ANNOYING
• Motion detection tells whether you walked into a building or are still in the car.
• Quiet at the places you choose, like home and work.
• One reminder per place and per trip, never a string of repeats.
Your places, visits and calendar stay on your iPhone.
