It works on your phone too — Open the tool in any modern browser on Android or iPhone. The layout adjusts to the screen and everything works the same way on a small screen as on a desktop.
Read the breakdown, not just the headline number — The result updates as you type. The breakdown underneath shows how the number was worked out, which is where mistakes usually show up.
