$$$
Get your wallet out. They want you to pay to measure in inches now.
good
es una aplicación muy buena y práctica, conveniente para medidas estándar y milimetricas, solo deberían actualizar el icono y hacerlo más estético con la versión de iOs 👌🏼👍🏼
I agree with ReginaY
I have used this handy ruler with inches on one side + centimeters on the other. Very handy! Now it only shows centimeters on both sides. If I still want inches I must pay a regular fee. Uh—no. I need no special features; just a simple ruler. I’m deleting it.
Misst nur in Zoll
Misst nur in Zoll / Inch , lässt sich in der kostenlosen Version nicht auf Zentimeter umstellen. (iPhone 15 Pro Max )
Works great, excellent user features, 2 very minor bugs
Each feature I tried worked really well and left me thinking “wow, someone actually tested and iterated on the UI.” I love that it doesn’t collect my user data. The tape measure feature takes a little finesse to be accurate. 2 minor bugs that are probably related: the “exit” and “rate me” buttons under the photo section don’t work.
was in cm asked for money for it to be changed into inches
Like my title said they had it in cm and I couldn't change it to inches without paying. I even tried to see how many cm are in inches but it was really hard to tell. It's free and no ads but still🙄
Menikmati
Sangat menikmati
Pay for cm->inches?
Most useful feature hidden behind a paywall. What a joke.
Mid
There are other apps that use the sensors in your. Using a reference object in the photo is a pain. 3 stars because it’s ok if you don’t need anything super accurate and are in a pinch.
Pay wall
This is a scam app offers almost nothing and u have to pay
Costs money for inches
Most basic app ever, charges money to measure in inches.
WhatsApp call review
Quite good, but sometimes other person goes quiet.
Don’t upgrade. Features behind paywall now
Can’t even measure in cm now without paying. Update just removes features to behind a paywall. Nothing new it seems. Rating lowered - wish I’d kept old version.
What about the Ruler Pro app ?
UPDATE: on my iPhone 14 Pro Max the ruler is lightly inaccurate. The displayed 150mm scale is actually 151mm. Not a show stopper for most people, it will be close enough. It has been more accurate on older phones, so hopefully it can be updated to be “good” again. ========== Annoyed that I paid for the Ruler Pro version previously but that it is no longer updated and have to re-buy the pro. feature in this version if I want the ruler to be accurate on the iPhone 14’s with 6.7” screens. Otherwise a great app that I’ve relied on many times !!
| a ruler
simple + effective— this developer gets it right
PAY FOR INCHES?
This dev wants you to pay for inches. He can take 12 inches right up his @$$
Can not change ref object
Good app but I can not change ref object
App was great until paid upgrade
I bought the paid version of this app years ago but now it doesn’t work on my new iPhone. Bummer. Back to this version with ads.
Ruler
Ok,used in my work
Engineer
Awesome app for engineers
Seriously Hot Garbage
The app has very sharp and professional looking graphics, which is what made me think I should take a risk on buying the application. Unfortunately the reference object concept is completely unusable. If I want to get a measurement it has to be something small enough that you can drag lines around to mark a reference object. Really? Am I supposed to tape a quarter to the side of my garage and then try to zoom in enough to put the reference lines on the quarter? I believe they are simply counting on the fact that you can't get a refund and even if you could wouldn't go through the hassle for $1.99. Don't bother.
Tape measure hangs up
Iphone 5s tape measure hangs up after 15 inches
Cm ONLY
You will need to pay for inches conversion. Fine if you are in the EU or metric system - but in true capitalist fashion - you will need to pay if you want to convert or live in America. Also not a ruler - rulers have both standard 🙃
Imperial only unless you pay
The free version of the app is largely useless since it only has inches on the ruler, and no cm
Excellent app, especially for what it costs
Tried various measuring apps, only - the one's that were free were terrible and the better ones all wanted a subscription. Once familiar with this one, I found it to be excellent and tested it to make sure. Took a photo of a ruler, set my reference point on the one inch mark, and it was spot on when I measured the inch mark on another place on the ruler. Even measured a bracket with an edge that was at an angle (in the picture). Even though it was off by .020", I was impressed. Anyone complaining about a free app like this, should save their energy and look elsewhere, as it fits my needs 🤗
No Inches
You have to pay to upgrade to get inches and centimeters
Helpful
I use it often. Simple and helpful.

The ninthgyhvj.
Warum der unnütze Rahmen??
Warum in der kostenpflichtigen Version der Zollstock diesen dämlichen Rahmen hat, werde ich nie verstehen. Ich nutze lieber die freie Version, ohne Rahmen.
Wow!
Wow!
Piece of garbage
Piece of garbage act hungry for subscriptions to use a RULER
Inaccurate
Nice app - but entirely inaccurate. I took a picture with a quarter in it to measure a crack and the default “quarter” measurement was 5 times the size of the quarter: Too bad it’s not accurate.
Bedienung ungenau
Die Messlinien verrutschen sehr leicht wenn ich den Touchscreen loslasse. Damit wird das Messen ziemlich schwierig. Bitte verbessern.
Ruler👍
Lol the reviews complaining about someone monetising their work is ridiculous.
Terrible
Can’t even switch from cm to inches without paying
You have to pay to use metric measurements
Unless you’re American, you might wanna just buy a physical ruler. Centimetres and millimeters are locked behind a paywall.
Love it
I love this versatile ruler app! Only complaint? Not enough ads!! 😝🤘I use this often to measure a special tool I have in my armada
Cheapskates
Can’t use non metric without paying. Filled with ads.
Stupid app
Keeps asking to upgrade like every 5 seconds. Why make an app if there’s a pop up every 5 second. Might as well put a price on the app and sell it instead than wasting our time.
Poo
You are poooooooiooooooooooooooo
Inches locked behind a paywall
Inches locked behind a paywall, centimeters only….
Waste
Waste of time. I have to stop using it after 15 second are you kidding me?? Apple makes one free with every phone
