Ratings and reviews

It coud be 5 stars. The developer please uodate the app. Why would this give an unrecoverable error? 2+2+=Error ! Why? None of the known calcuator brands will give error at this calculation. Sometimes this addition is very long and all my typing goes to hell because of this error. This is the only nuisance i find in this application. Apart from that it is 8/10 . You can improve the looks just a little bit. Add copy/ paste on the calculator display. And it will be perfect.

works great and looks good. does what its supposed to without any major setbacks.

Nice lightweight little calculator widget that does exactly what it says on the tin. Appreciate that the developer didn't load this down with adds or data collection, and the ability to set a custom background color to match my wallpaper is a nice plus. Have tried a couple calculator widget apps but I think this is the winner!
