## Calculate Reviews in United Kingdom

### *---- "Does not work"
2018 - just frozen.
-- petersanderson, 2018-02-16

### ***-- "Not working"
Doesn’t work on my iPhone 7 with iOS 11.0.3.  The numbers are invisible on the display area.
-- cobson99, 2017-10-28

### ***** "So simple and absolutely useful."
It's got me out of trouble many times. I'm glad it's sticking around.
-- Aodan99, 2017-10-19

### *---- "Won’t work"
Cannot contact the developer. So must post this review. The screen is grey with ghostly a “deg” and some other symbol appearing on the left but nothing you type in appears on the screen. The cursor moves but nothing else appears. I have an iPhone 5 with the latest IOS 11.0.1 update. So at the moment it’s a useless calculator
