24 alternatives to Sun light and path calculation for photography
I created this app to accurately calculate light windows like Golden hour, blue hour, etc. for a particular city/location. It helps you plan your photography time by knowing the exact time and direction of sun. It uses swiss ephemeris on the backend to calculate all the path and timings for most accurate data. It also has a 3D view of the sun's path on any day and at any point of the day for the location. Looking at the sun's direction and angle can help you plan your shoot correctly. It is a simple app with no sign-in needed or any ads. Hopefully it helps folks out there. Open to…

I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

Hi HN! I've been building Dayflow, a macOS app that automatically tracks what you're actually working on (not just which apps you have open). Here's what it does: - It creates a semantic timeline of your day; - It does it by understanding the content on your screen (with local or cloud VLMs); - This allows you to see exactly where your time went without any manual logging. Traditional time trackers tell you "3 hours in Chrome" which is not very helpful. Dayflow actually understands if you're reading documentation, debugging code, or scrolling HN. Instead of "Chrome: 3 hours", you get…

I shared this a little while ago. Since then, I've implemented some feature requests and added a small weather widget. There are also static pages for major cities if you prefer not to use the location-based version. e.g., https://sunrisewhen.com/new-york I know most phones and browsers already provide this kind of info, but it's a fun little project I enjoy keeping alive. cheers

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…

I love the sunlight and dread the long, dark winter evenings of Northern Europe. I often look up sunrise / sunset times and count off the days until the darkness is gone. Now I've written a terminal app for this (Mac/Linux) Features: a colorful summary of daylight times for your location; projected change over the coming days; handles NO_COLOR and a ---short flag if you dislike the output format. The location is IP-based but you can override this if you're on a VPN. Just create a terminal alias with the --loc flag. The app supports areas in the arctic / antarctic circle too.…

For the past few months, I've been working on a website that answers two different questions: - Where in my city have the best travel times to all the things and people I care about? - Given a listing, how far is it from all the things and people I care about? Personally this was fueled by my own frustrations when I was apartment hunting in NYC. I was frustrating to have to juggle so many Google Maps tabs when I was evaluating a listing, and it was also annoying to not have full confidence that I was even searching in the right places. I wanted to be close to work, a Trader Joe's, and a…

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. So we built a free app that uses your Apple Watch or iPhone to automatically track your light exposure throughout the day. 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!
