## Ruler Reviews in Соединенные Штаты

### ****- "Simple and easy"
This is a very simple, flexible, and easy to use ruler app.  No frills, just ruler.  I like that you can have just cm or just inches or you can have both.  Only thing I’d change is that when they have both it doesn’t line up at zero.  Otherwise it would be 5 stars.  Under the settings there’s a way to remove the ads in kid mode.
-- MyBookshelf, 2024-03-14

### ****- "Ay man it’s pretty cool"
Cool ruler, I had to measure something that we all know what it is.
-- Robloxlover01923, 2023-09-24

### **--- "No line from the start"
No line from the start
-- Large Minion, 2023-09-04

### ***** "Simply Perfect"
A thought experiment led me to search for this app. And sure enough, some genius had already developed it. In my opinion, every iPhone and iPad needs this. Mostly because I value quantification.
-- kogcyc, 2023-08-18

### *---- "Can’t see measurements under finger"
You can’t see the measurements under your finger as you adjust them. They should be slightly offset or fixed somewhere else
-- omfgus, 2023-08-16

### *---- "inaccurate"
inaccurate by a lot.
1 1/4 pvc is measuring 1 3/4” in the app
-- turtletwi, 2023-07-15

### *---- "Soporte"
Pantalla negra
-- davikitolopezcheca, 2023-04-02

### ****- "Make your ads disppear"
For anyone who is suffering from the ads, simply don’t give the app internet access (or change it later in settings), or take a screenshot and use it later in your photos. :)
-- john-dope, 2023-01-28

### *---- "No paid version anymore?"
I had paid for the version without ads several months ago. I just checked today and ads are showing on my app. On top of that, I don’t see an option to remove them. What’s going on?
-- dearwarsaw, 2022-07-24

### *---- "Totally Useless for U.S. Inches!"
Inaccurately portrays inch subdivision ticks between 1/2&quot; marks: 

It&#039;s either THREE ticks: 1/8, 1/4, 3/8... 

or SEVEN: 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16.

This ruler has FOUR between 1/2&quot; marks...WHAT?
-- Pedro_Antonio, 2022-04-16

### **--- "English units are not traditional"
The inches ruler is decimal; it should at least have an option to show 1/8’s or 1/16’s
-- Bill550, 2021-11-26

### ***-- "please fix hash marks"
People who use inches, use fractional inches that is 1/2, 1/4, 3/8, etc. Your increments are in tenths which actually make using inches very difficult
-- strattsp, 2021-11-22

### *---- "Measurements are inaccurate"
Measurements are inaccurate. The distance between one inch and two inches is bigger than a paper ruler. Also, when I clicked non App support there was a warning to not open the page as it was flagged as place that will try to steal personal information.
-- Brian 1955, 2021-10-30

### *---- "very shady"
tried to download for homework, another app that id never seen started downloading with it (a game). i can’t trust it.
-- 9 damage user, 2021-09-07

### *---- "Why would a ruler use tenths to measure inches?!"
Seriously! How can you tell what 1/16 looks like when an inch is marked out in tenths. I&#039;m guessing this was designed by someone who lives with metric.
-- doz+kaz, 2020-12-26

### ***** "No frills meauring"
An excellent little app. Just the job for visualizing the size of objects within dimensions of screen or, in scrolling mode, much larger objects.

Just what I needed!!
-- Rex Forester, 2020-10-29

### ***** "You Need To Download This App"
This is one of the best rulers on the App Store.   Simple to use, great interface, fluid, and the developer(s) listen to your feedback and are on the ball.  On one update the app did not work on my iPad.  I wrote them and within 48 hours a new update was available and fixed the issue.   I have contacted other developers on different apps and nothing.   This was amazing.  So you have a great app and great people standing behind it.  Not a brainer.
-- Marino3607, 2020-09-30

### ***** "Developer please read"
The app is great. The only trouble I find is that if you are measuring something, your finger gets in the way when adjusting the grid.  You should be able to click and drag from other parts of the screen to prevent this.
-- hiruko27, 2020-09-29

### ***** "Absolutely a great app"
So i was curious about what size my pocket watch movement was and i was able to use this app to measure it and figure out what size it was. This app is great for very small objects. I highly recommend if you are into scale model stuff or anything that has to do with small things
-- Rex2D2, 2020-09-14

### ***** "It is a perfect ruler app"
I never write reviews, literally this is my first review  ever and this app nails the task at hand so well I had to compliment it. Super simple and has every feature you need but not too many, simple layout. Brilliant
-- zigzag665, 2020-08-06
