I think that Apple ought to have something like this as a default and previously downloaded feature that comes with the devices they make (like the compass and calculator apps).

### 1/5 — Review of App

*2020-06-04*

Pointless adv-

### 1/5 — Ms MS

*2019-10-23*

beware... this is in a foreign language. Once installed, you can't get rid of it!!

### 1/5 — Cannot open on latest IOS system

*2019-10-05*

Please fix this app. Just updated iPhone to 13.0 and this app couldn’t be opened anymore. Very disappointed.

### 1/5 — ruler in cm  is totally wrong!

*2013-07-11, version 1.5.2*

Wrong!!

### 1/5 — 無故耗電，電池發熱

*2013-07-03, version 1.5.2*

4S下載使用後，無故一直耗電導致電池發熱，程式關掉也沒用，要刪除才行，使用要當心！

### 2/5 — Scales not real

*2016-03-06*

The idea is wonderful, having the area calculated as well, however both scales (cm and in) don't match with a real ruler.

### 2/5 — No longer happy

*2016-01-27, version 1.7*

Loved the app before i updated the new software version .  No longer get visual alerts with flash😤 please fix

### 2/5 — Highly inaccurate!!

*2015-03-05, version 1.7*

The ruler's 1cm is indeed 1.1cm!  10% error for a simple ruler!

### 2/5 — Glitchy

*2013-04-24*

App loaded quickly.  Had nice features like light and (coolest) a level.  Defaulted to cm, not inches.  That's OK.  Slide switch turns to inches.  Problem: when you switch to different program, like a web browser, the ruler program resets to default and loses your measurement.  No way to save old measurements either! 
Bottom line:  Needs too much work.  Don't bother...

### 3/5 — iPhone 6

*2015-08-18, version 1.7*

The ruler length and width is incorrect on iPhone 6. Please update. All other features are great.

### 5/5 — 最好用的尺子类工具

*2020-09-19*

功能确实很我试用多款软件对比后，发现最最好用的。而且很多功能小细节拉满，点赞。
唯一不足的可能就是刘海屏测面积，顶部无效位置也展示蓝色了，希望可以小小优化一下。刘海屏的origin.y修改一下就成。
