BYgo is a free light planning tool for photographers. Enter any city and it tells you whether conditions are worth shooting, when golden hour is, what the shadows will be like, which film to load, and what camera settings to start with.

Yes. BYgo is completely free to use and requires no account or registration.

How is BYgo different from PhotoPills?

PhotoPills shows you data. BYgo makes a decision. It analyses conditions and tells you directly whether to go out and shoot, rather than leaving you to interpret numbers yourself.
