## CalcQX LITE Reviews in United States

### ***** "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.
-- alm1959, 2020-12-04

### ***** "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!

I have used this app for years. Absolutely the best calculator app going.
