24 alternatives to Use iPhone's camera as a lux meter
After suffering one too many times from bad jet lag, I read a bunch of circadian rhythm papers and developed a simple app to help fight jet lag. I knew that avoiding devices at night was helpful, but it turns out that getting the right light at specific times of day can help not just with jet lag but overall sleep and well being. How it works: you give the app your sleep goal, and then it coaches you by estimating current melanopic light exposure from the iPhone's camera. I validated this against an $1800 lab-grade light meter and was surprised to find it is absolutely close enough for these…

I kept trying to explain how important outdoor light is and how most people aren’t getting enough. Eventually I figured that showing is more effective than telling.

It tells you if you’re getting enough, shows you how consistent you are, and rewards habits that support hormone balance. It's in beta on TestFlight, let me know what you think!

Hi HN! I suffered from chronic insomnia for over a year and tried everything from cutting coffee, blocking blue light, to taking melatonin and antihistamine, but couldn’t find anything that worked. I even bought a $500 research-grade EEG device to track my sleep, which was honestly kind of depressing because it showed that I was sleeping less than 4 hours per night for weeks straight. In the day, it took an immense amount of energy for me to perform even the most mundane of tasks, such as doing my laundry or ordering groceries. At night, I felt an overwhelming sense of loneliness and…

Virtual Sun▲101We built CircadianLab, a free in-browser tool for lighting design. It uses webGPU shaders to calculate melanopic equivalent daylight illuminance (mel-EDI, formerly EML, relevant for circadian rhythm and WELL v2 compliance), photopic illuminance, UGR glare per CIE 117, and actual daylight through windows and skylights. It has a database of 400,000+ IES files from 81 lighting manufacturers and supports easy sharing of scenes/configs with other people. Daylight uses the NREL Solar Position Algorithm and a Perez clear / intermediate / overcast sky model, mixed into the same…
