The Sporty’s website for the app at the bottom of the first paragraph states, “and an all new weight and balance calculator”.
However like an idiot I did not know Foreflight has a far superior W&B calculator. From your tail number alone gets the FAA stations AND the W&B envelope for your airplane type. The setup only requires entering the current empty weight and arm for your airplane. Once done you enter passenger and pilot weight, fuel and baggage and the W&B displays on the W&B envelope with a green dot on the graph if you are in and a red dot outside if you are out. It’s a beautiful thing!
