Buyer beware
Although this app says it is free, it is far from it. Not only do they charge an initial fee to build your W&B calculator (which I understand and would gladly pay...as we did when we had our CL30's built by SeeGee), but they want a monthly subscription as well! Once I purchase the program, there's no way I'm also going to pay a monthly fee...they use the excuse that that charge covers any weight changes you may have...if the weight changes that much, I'll pay for a new program.
