### 5/5 — Best Calculator for your Mac, your iPad, your iPhone

*2026-07-11, version 4.6.1*

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.

### 3/5 — The 0 (Zero).

*2026-07-07, version 4.6.1*

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

### 5/5 — Soo good

*2026-05-15, version 4.6.1*

Soo good good good no ads and everything you possible need

### 5/5 — Enfin !

*2026-04-18, version 4.6.1*

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.

### 3/5 — Be careful PERCENTAGE ERROR

*2026-02-26, version 4.6.1*

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

### 1/5 — Scribble Pad gets in the way!

*2026-02-09, version 4.6.1*

I’ve used Calc Max for over a decade (old iPad had no calculator) and loved its clean white display, simple basic functions but with good scientific mode when needed.
But now … WHO THOUGHT THE SCRIBBLE PAD WAS A GOOD IDEA AND WHY MAKE IT SO THST YOU CAN’T HIDE OR REMOVE THE SCRIBBLE PAD.
This App is now ruined!

### 4/5 — what a stud

*2025-11-09, version 4.6*

good calc.

### 5/5 — Great one!

*2025-10-22, version 4.6*

Easy simple calculator for everyday use. Love the tape! Makes it easy to re-check.

### 4/5 — Mostly very good

*2025-10-22, version 4.6*

Like how easy it is to read. I’m used to the equals key being on the lower right,

### 5/5 — Fixed!

*2025-09-27, version 4.6*

The best calculator on IOS. Now fixed to work with iOS26.
