Farmer Real/Estate Broker I bought the first 12C avalible back in the 70's, this app beats them all.
One darn fine calculator I love this thing. Still great! It has changed my life forever. Ed Falk is geeky great. Buy this and stop messing around with inferior renditions.
Just like my old HP-21 and 19C I love RPN. It's great to have the basic calculator again and the business one. Missed it for 15 years until I found this app.
Awesome. Highly useful. My go to calculator.
love it long time favorite!
Great App. I've owned and still own a HP 12C for over 40 years. This App replicates it to the T. Plus I "LOVE" the backup or erase stroke key. If I hit a wrong # instead of stopping and re-input the whole number, I can just back up that wrong digit. Thanks
