About

Independent comparisons of add-to-calendar tools, with every price sourced and re-checked weekly.

Most add-to-calendar comparisons are written by the vendors themselves, rank their own product first, and disagree with each other on basic numbers. This site uses one published rubric for every tool, links every price to its source, re-checks prices weekly and logs every correction in public.

How it's funded
