Leave a Review CalcQX LITE
Terrific calculator
I don’t use any of the scientific or trigonometry available but the memory slots and the ability to go back and see previous functions is the big seller.Dated but still Great!
Although this Calculator is dated(takes a few seconds to load) it has 4 addition, easy to use, memory slots. It also shows your last 20 calculations on another screen. If you make an error on a long entry you can back out of it number by number!Great app
I have used this app for years. Absolutely the best calculator app going.
