I'm a landscape photographer by heart and a software developer by trade. I build a web app for automating alerts for photography weather.

It is meant to solve the following issues I (and probably others) had: - the need to check multiple weather apps multiple times a day - keeping an eye out for some long range conditions like full moon or moon + azimuth - combining several conditions into triggers - notifications/reminders for those triggers

At first, I built a POC on my wordpress site. It was useful but hard to maintain, so I built a new one from scratch using C#, EF Core, Postgres, vanilla html/css/js.

Current functionality: - tracks locations the user saves, updates forecasts - allows to create alerts of two types: - simple conditions like high clouds > X, low clouds < Y, timing window = around sunrise - smart checks like fog or frost prediction, rain clearing, moonrise at sunset, open horizon - some spatial cloud calculations - moon table (up to 365 days ahead) for long range planning

There are some existing apps but I took a different approach. I didn't like the "magic scores" or "awesomeness certainty". Instead, it either triggers or it doesn't and gives you the snapshot.

I launched MVP several weeks ago so it is still WIP. I'd appreciate any feedback - UX, usefulness, etc.

PhotoSignal is freemium (1 location is free). But for HN, I'm giving a temp trial for all features and more locations.
