When you add long strings of numbers, they run off the screen and you can’t scroll to check them. If they had a word wrap type design you could check your input. Otherwise nice and simple!

Nice, clean, and simple app. Love the color. Very easy to use. Love it!

Love the dark them. Wish i could change the font color and it needs history to be useful.

If you make a mistake and enter the wrong number, you can not backspace and retype the correct number. You must delete and start all over from the beginning. Also this calculator can not add. I entered:1+1+1+1 then hit the equals button. What appeared was 1+1+1+1=3. I tried 6+6+6+6=. When I went to school that totaled 24. According to this calculator it is 18. 6+6+6+6=18. Has inflation affected our numbering system so much that 24 is now 18?
