MiEye measures light to help track your circadian rhythms and help you understand how you can use light to be healthier, sleep better, and feel better. MiEye was created by circadian rhythms researchers to capture real-world light exposure patterns and the effect on each photoreceptor of the human eye (all alpha-opic illuminances). From these data, MiEye models how light impacts the circadian clock. The MiEye app allows you to capture and process data the from your MiEye device.

Know what's really in your food and water. MicroPlastics turns your phone into a microplastics detector. Scan any food, drink, cosmetic, or container and get an exposure score in seconds, with the actual research behind every number. No account needed to start. WHY PEOPLE USE IT "I never knew." Most of us have no idea how much plastic our everyday habits add up to. A scratched water bottle, a microwaved container, that morning takeout coffee. They are not all equal, and now you can see the difference. HOW IT WORKS - Scan with your camera, a barcode, or a photo - We read the packaging: material, condition, and how you use it - You get a 0 to 100 exposure score (lower is better) and one clear next step - Every score links to the peer-reviewed studies it is based on SCAN AND UNDERSTAND - Scan food, drinks, cosmetics, and containers by camera, barcode, or photo - Ingredient checker: paste any ingredient list or cosmetic label to flag hidden plastics and polymers - Risk checker: estimate exposure for any material, including PET, HDPE, polystyrene, and glass - Shopping Mode: scan a whole cart and see its combined plastic load before you buy - Real citations on every score (ACS, PNAS, ScienceDirect, PMC) CUT IT DOWN - Lower-plastic swaps, free of BPA and phthalates, matched to what you scanned - Build a watchlist of what to avoid, from BPA and PFAS to phthalates and other additives - Save swaps or create your own - Avoidance guides: water filters for microplastics, glass water bottles, non-toxic cookware, plastic-free food storage, safer baby bottles, and more TRACK AND BUILD HABITS - Your Plastic Passport tracks exposure and progress over time - MicroQuests and weekly plans turn good intentions into small, doable steps - Room-by-room audits for your kitchen, bathroom, and beyond - A clean weekly report of where your exposure is trending - Streaks, stamps, and friendly challenges with friends DISCOVER - Find lower-plastic spots near you, including water refill stations, zero-waste stores, and farmers markets - Browse lab-tested products and their measured chemical levels - See what everyone is checking with Trending - Ask the Plastic Coach anything about microplastics, BPA, PFAS, or safer swaps THE SCIENCE The scoring model draws on peer-reviewed research, including: - Microwaving some containers can release up to 4.22 million microplastic and 2.11 billion nanoplastic particles per square centimeter in 3 minutes (Environmental Science and Technology, 2023) - One liter of bottled water holds about 240,000 plastic particles, roughly 90% of them nanoplastics (PNAS, 2024) - Repeatedly opening and closing a bottle can nearly double the microplastics in it (ACS ES&T Water, 2020) Every scan shows the specific studies used.
