Your tool saves me so much time. I can prep a load calculation before I get to a job site and then tweak it while on site directly from my phone or tablet. Keep up the good work.

Thank you so much for developing this tool. I use it my classroom to teach students how to perform a proper load calculation. I love the fact that it is free and I don't have to invest in expensive software.
