Best Calculator for your Mac, your iPad, your iPhone

I love this calculator. I have it on my Mac, iPad and iPhone. I’m not even sure what I would do to improve it, it seems perfect as it is. I recommend it highly.

The 0 (Zero).

The 0 (zero) key should be in the middle, between (.) and (=).
The rest is perfect.

Enfin !

Une calculatrice universelle pour mes appareils Apples (iMac, iPad) avec des touches de bonnes tailles. En plus les options d’exportations des données vers les autres applications (dont Excel) valent le coup de s’y abonner.

Be careful PERCENTAGE ERROR

Be careful when using percentage as it does not give correct results. I tested several times with other calculators. EXAMPLE USED: 4621.80 X24.33 percent = 1109.23. Except this is not correct result, it should read $1124.48. I did e-mail the developer and got no correction, no answer. I deleted the app on my new M4, 24” I Mac and re downloaded to get the lates version to no avail. (feb 25, 2026). Please fix it! and you will get 5 stars. THANKS
