    It's great now, smooth UI with history and memory recall and m+ and m- functions integrated in the touch based UI rather than buttons. Very intuitive to use. Amazing really, hadn't used this app from Google for a long time. Only thing missing is unit conversion and currency calculator. Full Review

    No C or CE button? Tried the help from the menu, nothing. I realize there seems to be this huge trend of making everything very neat and clean and simple, but fundamental functions need to be on things. I don't appreciate having to guess where things are hidden. We used to have menus for a reason. Put the menus back. Full Review

    Very clean lines. The C and CE functions are in the "clr" button which is sometimes "del". Memory function took me a while to work out but is accessed by a long press on the result of a calculation. It would benefit from a detailed set of functions so people can find these out easily. I much prefer this to the stock calculator on my s8. Full Review

    Really enjoy this calculator because it's fast and easy to use. The only thing it's missing is a clear all button. If you have an equation you're typing in and want to clear the whole thing (before hitting enter) you have to delete every single number one by one and it makes it sorta time consuming. Maybe I'm just overlooking this? I would love that too be the case because I enjoy the app, but it's just missing that one button. Full Review

    Although the UI is good, I found something. When I tapped the Result 3 times, a dialog box appears and it says "Unfortunately Calculator has stopped" I don't know if it's a bug or its normal. Full Review

    Great updates! Thanks for listening! The history and memory features are great. The new design is nice! Would be great if there was a tip and conversion feature thru swipe gesture from right side. Equal key should be much larger to take up empty space above. Full Review

    Use this calculator extensively. Fast to pick up and fast to use in a sticky situation. Follows Google's common visual themes which makes it fit in with other apps in your device. Can be used for basic functions but also intuitive in performing complex equations or scientific tasks. Can't quite perform graphing functions, but then again it isn't designed to. Very easy to use, very responsive and fast, won't fail you. Full Review

    Either remove implicit multiplication, or fix the precedence. Fix timeout on expressions such as “√√√√√√√√√√e”. Please add complex numbers, quaternions, matrices, arbitrary radix (or at least binary, octal, hexadecimal, and sexagesimal), polynomial solution (or guided simplification), differentiation, integration, and general algebraic manipulation. Real calculators use postfix application of single-operand functions. Not doing so makes it awkward to do calculations in multiple steps (which is sensible to check for errors): tap to insert prefix operators, and tap again to add closing brackets, each time risking mis-locating the cursor. Maybe for people who don't check partial results (or who've never used a real calculator) this isn't an issue, but I find it really awkward. Also, eww yuck, commas between thousands. And the paged swipe thing is just weird too. Please give me the option to uninstall pre-installed apps, or at least mark them as "hide, don't update, and don't remind me about updates". Full Review

    Only thing that might make this app better is a graphing function of some sort, but other than that, I've used this countless times and love the simplicity and feel. Full Review

    Awesome app, simple powerful nice look Nowadays most calculators only show decimal form of results while division. It might be new and a useful feature to show results as both decimals an in a fractions. So i hope you must add the new fraction mode to the next version. Thank you Full Review

    I really like this app, it's design and flow, but... The update was more of a downdate for me. I liked the feature that would convert any decimal into a fraction, that's gone. Also, I liked the previous color scheme, that's gone too! However it still beats the EMUI one that comes with my device! 😉 Full Review

    Dan Butterworth Published date: January 5, 2018

    No way to clear entered digits all at once until after a calculation. You have to delete each digit one at a time. No scientific calculator. To get a square root you have to put the radical in first. So that often means retyping a number from a previous result. Full Review
