Rechner Calculator App Reviews

This app fails the most simple Math test: 2 + 2 * 2. The answer is 6, not 8 (order of operations). Also, I have no idea what the instructions for the C gesture are telling me to do. And its annoying that there are no gestures for multiplication and division. How about diagonals starting from opposite ends, like the X for multiplication and / for division? Having to swipe and press a button takes longer than if the interface just showed the button.

While its true that the clear gesture should probably be a one finger operation, the app is absolutely beautiful and the gestures are innovative, useful, and intuitive. Very cool and very fast to use.

This app is fluid and works well, but I need it mostly for doing simple additions of percentages and can not get it to work. Has no help email or phone contact. Please help

Very nice app easy to get the hang of but needs exponents

when i put a decimal point in any operation when I try to get the result is always 0

The major problem I have with this calculator the very low precision, which is limited to three decimals. Slightly more complex calculations, especially multiplication and division, are almost not possible. I hope this gets upgraded soon and I will be happy to give more stars.

I love the concept, but it needs a lot of work. I have NEVER been able to use it because I cannot clear the screen. The gesture to clear is not well defined and never worked for me.

Fun easy calculator. Needs gesture to clear screen that does not require 2 fingers... Requiring 2 fingers requires using both hands. How about a double tap on white area to clear? Sounds are also kind of weird and distorted...

I really enjoy playing with this app. The only gripe would be the two finger swipe to clear the calculation. Its unintuitive with the rest of the functions.

The general idea is gret. I dont even have an issue with the two-finger clear gesture. But I cant for the life of me figure out how to use the % function (so much for "intuitive interface"). Unfortunately the "Tech Support Site" does not seem to have any means to send feedback or questions. Altogether I agree with those who have said that this is a good idea in development, not quite a finished product.

I really like the idea of a gesture calculator since you never know where the function buttons are from one calculator to another, but I found that this calculator doesnt do math! If you type in a four digit number with 2 decimal places, and subtract another four digit number with 2 decimal places, it returns a THREE decimal number. Hummm, not the math Im use to. But the real problem is that it doesnt do it all the time.

Intuitive, well designed, convenient

I really like the concept here but Im hoping theyll rethink the zeroing gesture. Users get comfortable using just one finger on calculators. Zeroing is a common operation and it breaks the flow quite a bit to have to adjust ones hand positioning just to do this. It also misfires if the two fingers dont land on the screen in sync.

I love the direction apps like this and Clarify are taking interaction on mobile devices. Good concept, well-executed. One suggestion - make symbols a bit bigger.

Looks great. But you released a calculator that cant do math? Update please.....

Two finger swipe back should be backspace. Other than that this is a great calculator.

This calculator is absolutely incredible. Its great visual appearance fits well with its easy to use gestures. Worth every penny.

A well crafted little app.

User interface is not intuitive. Requires you to remember gestures for arithmetic commands. I could not find help or explanation inside the app.

UI is great. The app looks great. The one glaring problem is numbers (decimals) being rounded. Otherwise great for quickly calculating things.
