Worldwide epic sunset/sunrise prediction

Me and my friends are hobbyist photographers. There have been too many times I missed the chance of going out for stunning sunset/sunrise. An accurate notification of epic sky would have helped us plan ahead much better.

So we built a service for sunset/sunrise prediction: http://miru.app/weather The main features include:
1. Prediction worldwide
2. Support up to 3 days of forecast
3. Fine-grained prediction for different kinds of sky (e.g., clear sky, too cloudy, clouds with multiple layers of colors)
3. An interactive map to view prediction at the city level
4. A notification interface that allows users to register and modify up to 3 locations

We also wrote a twitter bot that broadcasts every day the forecast for major cities worldwide: https://twitter.com/mirutravel/status/1388902516067213314?s=20

We are continuously improving our product. Love to hear any thoughts/feedback. Our contact is contact@miru.app. Hope you enjoy it!
