Ratings and reviews

Really recommended. Not like other calculator that cant hit button = consecutively. This even with history. Like upgraded ios calculator. Really love it to purchase premium

Please remove the bottom ads... It very annoying.... Other wise the app is pretty good..... Just the ads below is truely downgrade the ui performance..... its suddenly bring during calculation..... And one think I would like to say the placement of "0" should be at bottom left corner as aligned with top numerics digits...please have a look

The User experience is not good. I tried changing the orientation to use landscape mode and nothing happened. Half of the calculator is cut off the screen. Not worth the download. Waste of my time.
