I hope someone thought to take a bet for a decent amount, arguing that lidar and augmented reality on the iPhone are not a feature for the sake of a feature. And not tests of what is supposed to be used in future Apple devices. On several Apple devices available for purchase now, they transform the Roulette app into what it should have been all along. They didn’t say anything about this at the iPhone 12 Pro presentation. In the 90s, which almost became fatal for Apple, its management made a rule for itself: worthwhile technologies must advertise themselves. Are they making the same mistakes again, or simply did not consider what happened as an important event? Doesn't matter. We have already figured out how to use the new Roulette, and in this article we will tell you about it.
Nothing has changed on older iPhones, but on models with lidar everything is more interesting
The new Roulette app is only available on iPhone 12 Pro, iPhone 12 Pro Max, and fourth-generation iPad Pro running iOS 14, iPadOS 14, or later. On all other iPhones and iPads everything is the same, the Measure app is practically useless, like similar apps for Android. All of them really know how to measure the size of objects at a distance, but this is nothing more than a magic trick that makes a lasting impression on everyone to whom it is shown for the first time. The accuracy of their measurement (+/- 5%) leaves much to be desired. And an unacceptably large amount of time is spent on these measurements. The hand holding the device gets tired and begins to tremble, which further reduces the accuracy of measurements. But on devices with a lidar sensor, everything is different.
A few words about the Roulette application on iPhone
Roulette
is a free Apple app whose name says it all. It helps to measure the size of an object using the iPhone camera; the interface also has a universal level and the ability to calculate the area.
The iPhone Tape Measure app would be a really useful addition if it worked as well as manual measurement. But, unfortunately, this is not the case. Sometimes the probability of an error in Roulette reaches five or more centimeters, and this is sad. And that’s why a lot of users simply give up on it, opening it only once. Of course, the application was not created as a professional tool; it is rather intended for quick measurements, but you still want accuracy.
However, Apple and numerous foreign resources claim that Roulette has received an improvement with the debut of the iPhone 12 Pro | 12 Pro Max and LiDAR scanner. Well, this statement became very interesting, so I decided not only to give the Roulette app a second chance, but also to conduct a mini-comparison in which we compared the work of Roulette on the iPhone 12 Pro and iPhone 11.
What is it and why?
If you go back in time a decade, you can remember that previously there were no universal ways to solve various needs and needs. Each object solved a direct problem for itself: we talked on the phone, took pictures with a camera, listened to music thanks to the radio, watched programs on TV.
Nowadays, all of the above can be done thanks to a smartphone. Technology does not stand still; every day specialists in this field are developing technical support, the purpose of which is to simplify human life as much as possible.
The Roulette app, available on iPhone and iPad, is no exception. Modern realities boil down to the fact that even to measure objects and distances you don’t need anything other than your pocket gadget. This is possible thanks to the Cupertino augmented reality engine Apple ARKit 2.0, as well as built-in cameras.
The application is ideal for measurements that do not require engineering millimeter precision. It copes with everyday tasks with a bang. Measure the distance between two objects, calculate the area of a closet, measure a person's height - all this can be done using an application on your smartphone.
How does the Roulette app work on iPhone?
iPhone Roulette works using the iPhone's camera and internal position sensors. As soon as you open the app, iPhone asks you to show it the area so the sensors and AI can estimate the distance between objects and the general state of things.
To start measuring in Roulette you need:
- Place the cursor (white dot) at the beginning of the object whose length you want to measure. To do this, you need to move the camera.
- Then you should tap on the big circle to make a dot.
- Then simply draw a line to the end of the item and tap again.
Shapes such as rectangles and squares can be recognized by the system and form a quick area measurement. But with round surfaces in Roulette it’s generally bad; the system cannot recognize a sphere or a circle, so you won’t be able to quickly calculate the area or volume.
To make the application work better, you need:
- Place items on a flat surface.
- Zoom in, then zoom out.
- Adjust the outlined lines, adjusting their size exactly to your subject.
- Take light into account; without it or with poor light, the application works even worse.
Taking a single measurement
- Open the Roulette app and move your device according to the on-screen instructions. Thus, the device will receive a coordinate system of the measurement object and the surface on which it is located. Continue moving the device until a circle with a dot in the center appears on the screen.
- Move the device so that the point is above the starting measurement position and click the add button ().
- Slowly move the device until the point is above the final metering position and press the add button () again.
After taking a measurement, you can change the starting and ending points of the object. Touch and hold one of the dots and drag it to the desired position. The metering values will change as you move.
Are Roulette measurements different on iPhone 12 Pro and iPhone 11?
Yes. But these are purely minimal changes, which (as for me) do not affect the quality of the measurement.
What has changed in Roulette on iPhone 12 Pro with LiDAR:
- Now the iPhone asks them to “move” less; with the help of a LiDAR scanner, the device better perceives what is being measured and where the object is located. This eliminates the need for unnecessary movements.
- Added definition of centimeters. When you move away or bring an object with a drawn point closer, centimeter divisions begin to appear on the screen. Quite convenient.
- The device can now detect straight lines.
- There is a list with the history of measurements. You can go to the menu on the top left and view all measurements.
Has the measurement quality improved? I wouldn't say so. If you visually compare the tape measure on the iPhone 12 Pro and iPhone 11, the differences in measurements are not that big.
Here's the box measurement for the Apple Watch Series 3:
- Manual measurement showed that its dimensions are 32 cm x 7 cm.
- The iPhone 12 Pro showed dimensions of 35 x 7 cm. In another measurement, the length of the box was 32 cm.
- iPhone 11 measured the box as follows: length 31 cm and width 7 cm. There was an option where iPhone 11 also showed the length of the box as 33 cm.
Measuring the Pelican iPhone 11 case showed the following results:
- iPhone 12 Pro: 8 cm x 15 cm.
- iPhone 11: 8 cm x 15 cm.
- Manual measurement: 7.7 cm x 14.5 cm.
As you can see, depending on what we are measuring, how it looks and where it lies, the final numbers can be measured both with errors and quite accurately. You can take this into account when working with Roulette.
But I must say that after this experiment I was pleasantly surprised by the application. Yes, there is an inaccuracy, but in my case it was up to 1 centimeter.
Problems and solutions
Since this technology is relatively raw, although the application works stably, it is still not ideal. Due to the lack of sensors other than the camera, as well as in low light conditions, measurements may not be accurate. But in reality, everything is not so bad - the error is usually no more than 10%, and with each software update it tends to be minimized. And objects that contrast with the background tend to be measured accurately.
In order not to encounter the problem of accuracy when measuring, it is enough to follow only three rules:
- The application must correctly determine the measurement plane;
- It is necessary to avoid that the measured object blends into the background;
- Good lighting in the room is desirable.
iOS just recently welcomed the release of update 12.2, in which Apple again paid great attention to performance and speed. Many software details have been redesigned to improve the performance of built-in applications. “Roulette” has also undergone changes due to optimization of the camera.
Now, this application may not be a solution for all occasions, but a new big update to iOS 13 is already visible on the horizon, the release of which is expected to take place on June 4, 2022. It is expected that this update will be the largest since iOS 6. So we will expect new successes in the work of the updated programs. Share link:
What would you like in Roulette on iPhone?
Accuracy.
Now Roulette is not very accurate, this is noticeable from my experimental measurements. I would like the phone to be able to replace everything in the near future: from a computer for games to a roulette. Reducing the error rate should be the main goal for improving Roulette.
Adding definitions for other shapes and
quickly calculate their area, volume, perimeter and so on. This would be quite useful for anyone, I think, because you never know when you will need to calculate the area of an object. It would also be useful for children for school.
Adding multiple objects.
Now when you measure one object, you cannot add another one to it and compare the indicators. Even to draw two lines you need to combine them. As for me, this is a completely ill-conceived scheme. What if I need to measure the areas of two shapes and compare them? Measure separately?
Saving measurements
When the measurement displays, tap the number to display it in inches or centimeters. Click "Copy" and the value will be sent to the clipboard so you can paste it into another application. Click "Clear" to repeat the measurement.
You can also take a photo showing the subject and its measurements. Simply press the camera's shutter button () and the photo will appear in the lower left corner of the screen. Tap it to edit it using Markup, or swipe left to save it in the Photos app.
conclusions
Roulette in the iPhone 12 Pro has improved, but only slightly. The tool is still not the most reliable for determining the size of something. But it can be used if you take into account the possibility of error, as well as the factors that I described above.
But I was pleasantly pleased with the Level in the Roulette application. It can be used as an electronic level if you need to measure something very quickly. Thanks to the sensors built into the iPhone, the indicators turned out to be accurate.
I hope that Apple has not forgotten about its application and will be able to put it in order in the future.

Additional program functionality
In addition to measuring objects, the application allows you to control the evenness of objects. To do this, in addition to the main roulette, the application allows you to use a level. It is selected in the corresponding section at the bottom of the screen and helps to hang any object in the house evenly, showing the level of inclination. To use it, you just need to press your smartphone firmly against the surface of the object, after which the current level of evenness will be displayed on the screen. Also, the smartphone display immediately shows which plane the distortion is on - vertical or horizontal.
In general, the level works accurately due to the built-in gyroscope in the smartphone, so you can be sure that the information provided is correct.
Measuring human height
When the Tape Measure app detects a person in the viewfinder, it automatically measures their height from the ground to the top of their head, hat, or hair. You can press the shutter button () to take a photo of a person while measuring their height. You can then use the Markup feature on the photo, save it, and share it.
Tips for measuring height correctly:
- Choose a place with good lighting.
- Avoid choosing a location with a dark background or near reflective surfaces.
- Make sure that the face and head of the person whose height is being measured is not covered by anything (such as a mask, sunglasses or a hat).
- Try stepping back from the person whose height you are measuring. You may be standing too close.
How to turn off iPhone 12?
Restarting iPhone X, 11 or 12
- Press and hold the Volume Up or Down button and the Side button until the Power Off slider appears.
- Move the slider and then wait 30 seconds for the device to turn off.

Taking multiple measurements
- After taking your first measurement, move the device to position the point above or near another location on the subject.
- Press the add button () to start a second measurement and move the device so that the point is located next to the location of the already taken measurement.*
- Press the add button () again to display the second measurement.
- Repeat these steps to complete the required number of measurements.
Click the cancel button () to delete the last measurement, or click Clear to repeat.
*Additional measurements must begin or end close to the measurement already taken. Otherwise, all previous measurements are replaced by the most recent one.
We measure the room using a mobile phone
If you want to measure a room, you don't necessarily need a meter or laser rangefinder. You can use your smartphone instead. The Moasure app works on both Android and iPhone models. It uses smartphone motion sensors and accelerometers. The app does not need a camera to measure.
Before you take your first measurement, you will need to calibrate the application. To do this, hold your smartphone up to the wall so that the arrow on the screen is pointing up. Once the process is complete, you will be able to measure everything around you.
Among other things, Moasure can be used to measure room heights or angles. There are corresponding manuals for various measuring operations. The process requires placing the smartphone at the beginning and end of the object/distance. Accordingly, if you place the gadget in the corners of the room, you will be able to calculate the area of the room. And if you take into account the height value, which can also be measured in the application, you can calculate the volume of a room or object.
If you want to measure a long distance, it makes sense to set intermediate measuring points. To do this, simply place your smartphone one by one on several points of one line.
