## Most critical reviews (8 lowest-rated)

### 1/5 — dodgy!

*2024-01-09*

- inaccurate, cms divided into 16 subunits. like inches, not 10 mms as any normal person would expect
- wants to connect to bluetooth. why?
- full screen unskippable game ads in your face

### 1/5 — Wrong measurement!

*2022-01-14, version 1.3*

On my iPhone 13 Mini, this gives the wrong measurements. Obviously doesn’t detect screen size like most of the other ruler apps.

### 1/5 — Noisy ads and not accurate

*2022-01-13*

I try to use this in a quiet setting and an a video ad at full volume popped up. App developers like this should be sent to the gas chamber.

### 1/5 — Trash

*2021-08-02*

Used it for math during COVID and it’s not even right

### 1/5 — Not accurate

*2019-12-15*

The ruler is not accurate. It is shorter than the real inch and centimeter.

### 1/5 — Wrong measurement

*2019-09-07, version 1.3*

Misleading measures
14cm=10cm real
What a mess

### 1/5 — Not even accurate

*2018-09-18*

Thanks for failing me on an assignment

### 1/5 — Doesn't work at all on my iphone6Plus

*2015-05-05*

Doesn't work at all and annoying games appear. WORTHLESS USELESS APP!!!
