### 5/5 — Best Apple Watch calculator!!

*2020-03-16, version 3.5*

I have went thru about 6 calculators for my watch and this is the best.   First, it is very simple.  If I want complex I use my iPhone.  Next, the buttons are about as big as possible.  But the stoke of genius was adding a tape of the calculation along the top so you can be sure you put in the right numbers.

### 1/5 — Doug

*2019-01-17, version 3.4.8*

Worked for a while. Then died. Uninstalled. RE installed. Still no worky

### 5/5 — Perfect for iWatch

*2018-12-17, version 3.4.8*

Very simple calculator with large numbers makes it perfect for my new iPhone.

### 1/5 — Not working

*2018-10-23, version 3.4.8*

It’s not working on my I watch. I installed it from my I watch apps it will open on my phone, but not on my watch.

**Developer response:** The app may take a few minutes to install. Please update to the latest watchOS and check it is installed in "My Watch" tab.

### 4/5 — Works fine

*2018-10-23, version 3.4.8*

I just installed this app and its working fine on both my phone and watch as of 10/23/18.

### 5/5 — Fantastic.

*2018-10-12, version 3.4.7*

I’ve looked at a ton of these apps .. this is the best layout for me.  All the basic functions on one screen without having to go back and forth ... also handy is keeping the function key a different color after it’s depressed.  

The only thing that would make it a bit better would be a horizontal tape at the top.

### 1/5 — Did not work

*2018-10-04, version 3.4.7*

I purchased the app and it didn’t work on my watch. I tried restarting both my phone and watch and nothing worked. I emailed the manufacturer. I’m waiting on the response.

**Developer response:** Please make sure watchOS has been updated and the app is installed under "My Watch" on your iPhone's Watch app first.

### 1/5 — This app needs work!

*2018-09-23, version 3.4.7*

Didn’t work on my Apple Watch which is the reason I got it in the first place. I wish they would fix this!

**Developer response:** Please make sure watchOS has been updated and the app is installed under "My Watch" on your iPhone's Watch app first.

### 1/5 — Does not work at all

*2018-08-11, version 3.4.5*

This app doesn’t even show up on watch at all. Wasted a $

**Developer response:** Please make sure it is installed in the Watch app under "My Watch" on your iPhone app first.

### 5/5 — Everywhere

*2018-07-11, version 3.4.5*

I use it in my phone and pad
