Function Calc

This is probably THE MOST POWERFUL calculator app in existance today. And it is completely FREE and SECURE. The only dowside is the almost vertical learning curve.

Hugh, I have dedicated some times to evaluate your product. I rate it as 5 although it needs some enhancements. Kindly please find time in future versions to include if , for , else or then statements, loops, max and min to make it the greatest. Even more so it is able to add graphics on the background for a certain repetitive problem. I salute you even more as you are giving it free to humanity and for that you are truly blessed. Hope to see these enhancements soon and more feedback from me. Thank you very much! Vernon P., PE, MAA emeritus

Very good calculator app. Wow, no ads and it’s free. Thx
