### 1/5 — Measurements not accurate

*2020-05-10*

Measurements are not accurate and way off.

### 1/5 — Inaccurate

*2018-09-23, version 2.2*

The ruler is inaccurate on my iPhone 6s Plus

### 1/5 — One inch is not one inch

*2018-08-16*

With this ruler, one inch is about 1.3".  This is not helpful in my very precise world...

### 1/5 — Thumbs down.

*2018-07-12, version 2.2*

Totally inaccurate. Need to 'buy' different rulers. Gives very little instructions about how to use. Disappointing.

### 2/5 — Not accurate

*2018-05-23*

I have an iPhone 6s and the inches aren’t accurate. 2” in real life measures 1 3/4” on the phone. I thought I was going nuts trying to measure something...

### 1/5 — How did the app review let this get through?

*2018-01-07, version 2.2*

First, it can’t even accurately do its main purpose on any device aside from whatever device the developer made it on. I have an iPhone 6S Plus and one inch is actually about 2 because the app is auto scaled up to the phone’s native resolution. 

Second, the app has a child like theme to it, which makes it even worse as kids trying to learn will learn the entirely wrong way. 

Developer: I suggest you pull this app down so you don’t trick people into believing their wee wee actually is an above average size.

### 1/5 — Scale incorrect on iPhone 6S Plus

*2017-02-08, version 2.2*

Scale incorrect on iPhone 6S Plus

### 1/5 — Doesn't work

*2017-01-15*

Garbage

### 1/5 — Inaccurate

*2016-10-02*

Needed to measure something less than an inch. It was off by an with inch.

### 1/5 — Garbage

*2016-05-10, version 2.1*

Utterly useless. 2 inches is all you get unless you pay for an upgrade. Cannot even measure a piece of paper, it is such CRAP.
