Not having to manually calculate Katch-McArdle BMR formula?

Could we please have this forumula for BMR? I do not understand why there is a disconnect. It does not even need to be default. It's something needed, something no one else offers. This app asks for Body Fat %, then why not actually use it?

There's the forumulas. Please add one more.

900 difference in calories for me, between Mifflin St Jeor and Katch-McArdle.

Anyone else?
