Actually there are some problems It does the basics fine (normal calculation) but the percentages don't work in the way I would expect a normal calculator to work. You can't add a percentage to an original figure, for example - just get the actual percentage, and you would have to use the memory buttons to complete your sum. Which clear when you press them to start a calculation, which is another issue. Also not fond of the positioning of the multiply and divide buttons. Keymapping would be great, if the dev won't move them all to the right-hand side.
Does what it says, good widget I get 6/8 = 0.75 so I don't know what everyone else is complaining about! Works fine for me. Pantech burst.
Poor design Buttons are not proportionally sized for the widget. The big size has muttons cut off. Percentage button does not work at all. Galaxy S4
Pretty good Works just fine. Would be nice if you could change the background/font color in the free version. HTC Hero S
Poor widget. Did not calculate correctly. Calculator will not do percentages. Uninstalling
Good but missing a few things I really liked the widget until I realized there is no decimal button or 0 button. Thats a little important.
