## Most critical reviews (10 lowest-rated)

### 1/5 — non responsive

*2016-02-26*

Q. How hard do I need to press on the screen to get this app to respond? 
A. To hard.
So is this app any good? 
In one word NO!

### 1/5 — Slow & unusable.

*2015-11-20*

This is even worse than using one of those old Casio calculator watches. On a touch screen you can't tell if you've pressed the button, and the app is so slow to respond it makes it unusable. 

Nice try, looks nice, but failed miserably.

### 1/5 — Buttons too small

*2015-08-27*

Only the 0-9 numerals should be on page 1. 

Fiddly. 

Deleted.

### 1/5 — Doesn't work

*2015-08-06*

Don't waste your time on this. It doesn't work at all.

### 1/5 — Not working

*2015-07-01*

Operator buttons do not respond. No use at all.

### 2/5 — Great app, but lacking watch os2 support

*2015-09-23*

This is a great calc, but really needs updating to support watch os 2 native apps. Calculations are very slow over bluetooth! Please get this sorted. Thanks

### 2/5 — Watch calc is slow

*2015-08-04, version 1.0*

Poor performance 😩

### 2/5 — Nice idea but functionally painful

*2015-06-29*

Looks good, offers plenty of basic calculator functions on your wrist. However it is painfully slow to respond to number entry and frankly I had a faster calculator watch in 1979 on my Casio I had at at school back then. If this is the best it can do it needs to go back to the drawing board.

### 3/5 — Nice looking app, but...

*2015-04-25*

I like how it looks, but needs a way to correct input, not just AC. Also needs to highlight operator - did I hit +, x, anything?

### 4/5 — Fine

*2015-08-11*

Works fine , handy for the watch

### 5/5 — 🎈PLEASE UPDATE

*2018-09-11, version 1.0*

Please update this app. It will not work with future iOS updates. It’s a good app. It’d be a shame to lose usability.

### 5/5 — Works well

*2015-07-07*

Works well, little slow on watch but delay is over Bluetooth.. Looking forward to watch os2 so it runs on watch itself

### 5/5 — Perfect

*2015-05-19*

Perfect for cheating on tests😁

### 5/5 — The best calculator for the Watch

*2015-05-13*

This is the best calculator for the Apple Watch I've found so far. It's very simple, without any unnecessary functions. I won't use any trigonometric or other scientific functions on my Watch, that's what I use my iPhone's built-in calculator for.

### 4/5 — Good for a simple +-*/ calculator on Watch

*2015-07-14, version 1.0*

This one only does the simplest operations but at least all the numbers and operators fit on one screen. Should give visual feedback on operator taps so we know it has registered each tap. Decent enough that i will use this for simple calculations.

### 4/5 — Looks good. Needs a glance

*2015-06-27, version 1.0*

One of the nicer looking calculators. Like every other watch calculator I've tried buttons are a bit unresponsive. I think this has more to do with the watch than the app. Needs a glance for easier access which is what I subtracted the star for. Because of the name, Siri just will not open the app. Wants to keep opening other apps instead even though it understands I'm saying watch calc.
