Rechner Calculator App Reviews

Love the elegance of the app. But please replace the Double Finger gesture for clearing by à Double-Tap.

When you try to use a decimal number (lets say, 2.5), it fails to add, substract, multiplicate or divide the next number. It reinitializes to zero. I might not using it correctly, but it seems that easy; then feels buggy.

Only integers, no float !

It broken, If you make some + (plus) account with some fraction number (ex: 10.3 + 6) the result is aways 1. If you plus two fractioned numbers the result is 0. I didnt test the other aplications. Layout and usability are preety good but I would change the other signals (x, %, √...), i think it will better if when you swap to down show the entire signals table on the numbers place, and when you chose one those signals the numbers come back again. I wait for the update with bugs fixed.

This calculator actually isnt able to calculate accurately. Further it does not floating point numbers at all. The developers have to fix these problems. Suggestions: Make horizontal two finger swipe for "equals". The raising operations plus and multiply one finger right and one finger up. The decreasing operations minus and divide one finger left and one finger down. Access menu by two finger double tap.

Null, nothing, nada!

Fun and engaging calculator. Once you get used to movements, a great alternative to the the everyday utility.

Interesting, easy and fun! Nicely designed! Vertical Ski Hound......

However, the fact that NOT all operations are gestures is annoying. Try app "Calculator Touch" - it has gestures for ALL operations plus it allows color change and also it is Universal app for iPhone & iPad!

This calculator computes in the order it is entered, not following basic math principles. For example 2+3x4 should be 14 but with this calculator it does the addition first since it is entered beforehand and gives 20 as the answer. May be pretty but completely useless in real life uses. Do not buy if you intent on using with more than one operations!!!

stylish UI with simple function. hard to clear and start another calculate again. suggestion; why dont you add shake to erase gesture command!

Looks gorgeous but realization of idea is still poor.

An updated version is cool! I hope they dont kill it with very complicated one the next time!

From my point of view the world does not need a gesture based calculator. I tried it and I can say the classic "+" button is faster and simpler than gesture. If you need multiplication and division you have to: 1. swipe 2. press the icon/button Most important thing, the calculator doesnt work! An example: 100 / 0,5= 0 Guys, you should improve your testing before launching a product. A bad user experience over a broken product.

Love the interface... Looks like Itll take a min to get used to, but I dig it!

Looks innovative and works good, the only issue I see is that to clear you need 2 fingers, and interrupts your 1 thumb flow.

Nice looking app, and gestures are surprisingly usable for plus, minus, and equals. MAJOR concern - "clear" requiring two fingers is crazy. Makes one handed operation, which is my usual on my iPhone, very difficult. Maybe a circle gesture, or zig zag, or swipe at the top? Even a shake would be better than the two finger swipe (shake in addition to the two finger?). Other suggestions: add more features for multiply and divide. These need to be immediately accessible! Maybe theyre diagonal swipes in opposite directions? Opposite sides? These are quick thinking ideas. Looking forward to the progress, but I appreciate the design.

Beautiful and efficient and in keeping with the intuitive nature characteristic of MacOS gestures. I agree, thumb friendly clear would be advantageous as well as gestures for multiply/divide. I like the diagonal strokes in opposite directions idea!

200% more efficient? I highly doubt it. Its a very basic calculator, which is totally fine. But the fact that some functions are gesture-based and some are NOT makes your brain constantly switch between gestures and taps, thus making it 200% less efficient. Getting-used-to is extra work. Alas, extra work is not efficiency. Issues: CLEAR gesture should be able to be performed with one finger. 99% of people operate their phones with one hand. So please, come up with a different gesture. Percentage function: 10+50%=15, NOT 60. Fix it.
