Let's get straight to the point: No cell phone can take X-rays.. There is no phone with an X-ray source or a detector capable of capturing this type of radiation — the phone's camera only sees visible light. Therefore, all apps that appear in app stores with names like "X-ray," "body scanner," or "radiography" are fraudulent. prank apps (the so-called prankThey display a fake skeleton image superimposed on the camera screen, like a pre-made visual effect. Nothing that appears there has any relation to your body. These apps are for entertainment purposes only and are not a substitute for imaging exams or healthcare professionals.
That said, the prank is popular and continues to generate good laughs among friends and family. In this article, we explain, in simple language, why taking an X-ray with a cell phone is physically impossible, how these apps create the fake image, which prank options are actually available on the Brazilian Google Play Store today, and, finally, how to take a real X-ray in Brazil.
Why no cell phone can take X-rays
An X-ray depends on two parts that a cell phone simply doesn't have. The first is the X-ray sourceA tube that accelerates electrons against a metallic target, under high voltage, to produce ionizing radiation capable of penetrating soft tissues and being stopped by bones. This tube is heavy, requires cooling, and a power source far exceeding that of a smartphone battery.
The second piece is the detector, On the other side of the body, a sensor records what has passed through the patient and transforms it into an image. The sensor in a cell phone camera is designed for visible light: it doesn't "see" X-rays, and even if it did, there would be nothing to see because there is no emitter on the other side. Without a source and without a detector, there is no radiograph—not even with the best app in the world.
There is also the issue of safety. X-rays are ionizing radiation, and their use is regulated in Brazil by ANVISA (National Health Surveillance Agency) and the National Nuclear Energy Commission. Equipment requires a license, a shielded room, and operation by a qualified professional, and the examination is only indicated when the diagnostic benefit outweighs the exposure. A device capable of emitting X-rays in your pocket, without any control, would be a serious public health problem—not a convenience.
How the fake X-ray effect is created
The trick is much simpler than it seems. The app opens the camera to give the impression that something is being scanned, plays a scanning animation with a sliding bar, machine sound and countdown, and then displays an image over it. generic image stored within the app itselfA skeleton, a ribcage, a hand, the inside of a bag. It's always the same figure, no matter who you point it at.
You can check this yourself in ten seconds. Point it at two people of different heights, or even at a wall, and compare the result: the "X-ray" remains identical. Some apps let you choose which part of the body to show, which is definitive proof that the content is pre-fabricated, and not captured on the spot.
What the store says about these apps is less helpful than it seems. Of the five titles we've listed below, only two are rated in... Entertainment On the Brazilian Google Play Store — the other three appear in Tools and even in Education. And the warning about "prank," "trick," or "for entertainment purposes only," present in the description of four of them, simply doesn't exist in the fifth, which is still advertised in the store itself as a "real body scanner." In other words: neither the category nor the description serves as a guarantee. What doesn't change is physics — and it has already proven that no cell phone can take X-rays. The fun of the joke lies in the reaction of those who don't know the trick, and it ends the moment someone truly believes that it's an examination.
5 fun X-ray apps available on Google Play
We compiled the options that are actually published in the Brazilian store and checked each listing before compiling them. All are free., They display ads., None of these apps charge in-app purchases, and all of them function as visual effects—none of them perform any kind of examination. We indicate for each item the category in which the app is classified on Google Play and whether or not the description states that it is a joke. Several popular titles from years ago have left the store and are therefore not included in this list.
1. X-Ray Body Scanner Prank Cam
O X-Ray Body Scanner Prank Cam It's the most straightforward of the group: it opens the camera, runs the scanning animation, and returns a superimposed skeleton image. The app's description itself warns that it was made exclusively for entertainment and simulates an effect similar to that of medical or security scanners, without producing any real results.
It's a lightweight app, without in-app purchases, but with frequent ads between screens. It is rated in... Entertainment On Google Play, the summary of the product description states that the scanning effect is "purely for entertainment"—the store, in this case, is honest with the reader. It's meant for a quick prank with someone nearby and nothing more: the generated image does not correspond to anyone's body and should not be shown as if it were an examination.

Android2. Wall Scanner Xray Prank
Instead of people, the Wall Scanner Xray Prank It pretends to scan walls: you place your phone against the surface, tap "scan," and the app shows a fabricated image of what would be on the other side. It's the best-known on the list, with over a million downloads, and the description itself clearly states that it's a joke and not a real X-ray.
It is also in Entertainment On Google Play, the description ends with a prominent warning stating that it's a joke app, "not a real X-ray." Even so, the average rating is low, and a large portion of the negative reviews come precisely from those who installed it thinking they would be able to see inside the wall. It's worth remembering: to find pipes or wiring, there are physical wall detectors, devices specifically designed for that purpose. A cell phone doesn't do that job.

Android3. X-Ray Camera Friends Prank
With a Portuguese interface, the X-Ray Camera Friends Prank It lets you choose which "body part" you want to display before pointing the camera — hand, torso, skull. This detail already reveals how it works: the figure is selected by you in the menu, and not captured from the friend in front of you.
The app's description explicitly treats it as a prank and asks users to enjoy the jokes "responsibly," making it clear that there's no real X-ray involved. A curious detail: despite the content, it's not listed under Entertainment on Google Play, but rather in [other app categories/sections]. Tools — another reminder that the store category says nothing about what the app does. It's a reasonable option for those who want the text in Portuguese during the prank, with the caveat of always telling the truth right afterward.

Android4. Xray Body Scanner Prank Camera
O Xray Body Scanner Prank Camera It's one of the newest of its kind and works offline, since all the "scan" images are embedded in the app—further confirmation that nothing is processed or analyzed. The animation is elaborate, which enhances the surprise effect.
The summary on Google Play states that it's an app "for hilarious pranks, purely for entertainment"—that is, it warns the reader before installation. However, the rating chosen by the developer is... Education, This makes absolutely no sense for a prank simulator and reinforces the need to read the description before relying solely on the category. Being a recent app, it hasn't yet accumulated enough reviews to have an average rating in the store.

Android5. x ray scan v3.0: Funny Camera
O x-ray scan v3.0: Funny Camera In practice, it's a photo effects app: the "X-ray" is just another filter in the catalog, alongside thermal effects, distortion, and color and contrast adjustments. But it's also... the most problematic case on this list. He is ranked in Tools On Google Play, the store summary presents it as a "real body scanner," and the Portuguese description doesn't mention the words "prank," "joke," or "prank" even once—no warning that it's a visual effect. Anyone who only reads the description might install it thinking they'll see bones.
What it actually does is increase contrast and apply a whitish texture reminiscent of an X-ray film, with no relation to internal body structures. It works for memes and joke photos, and the description itself mentions "photographic effects" and making the image "similar to an X-ray scan"—similar, and nothing more. Install it knowing what it is: an image editor. No part of it scans anything.

Android
And on the iPhone?
The Brazilian App Store also has versions of the same game, such as... X-ray Scanner Simulator and the X-Ray Scanner Body Prank, Both are free. The logic is identical to Android: scanning animation plus a ready-made image on top. The ratings are also low, for the same reason as always — many people install expecting something that neither device can deliver.
Precautions before installation
Don't use the image to talk about health. Showing someone a screen and telling them there's a fracture, a kidney stone, or any other finding is an unnecessary scare and can lead the person to delay seeking real medical attention. Make it clear that it's a prank as soon as the reaction occurs.
Pay attention to the permissions. An app like that only needs access to the camera. If it asks for contacts, location, messages, or files, be suspicious and look for another app. It's also worth reviewing the permissions granted in your device settings after you've had fun.
Count on advertisements. All the listed titles are free and rely on advertising, often displayed full-screen between actions. And, if the game involves children, explain the trick beforehand: the image of a skeleton can be quite frightening for those who don't yet understand that it's a montage.
How to take a real X-ray
The process begins with a consultation. An imaging exam is ordered by a doctor or dentist, based on a clinical indication—persistent pain, suspected fracture, pulmonary evaluation, dental treatment planning. No radiograph is useful without someone to interpret the results within the context of your specific case.
Through the Brazilian public health system (SUS), the request comes from the basic health unit or emergency room and is scheduled within the public network, free of charge. In the private sector, health plans usually cover the exam with a doctor's order, and imaging clinics also offer private services. In either case, the exam is performed by a radiology technician, and the report is signed by a radiologist.
If your concern is distance or cost, talk to the staff at your nearest health unit before looking for digital shortcuts. No app—paid or free—solve this, and postponing a recommended exam because you believe a false image is the worst possible outcome.
Frequently asked questions
Is there an app that can actually do X-rays?
No. No app transforms a cell phone into radiology equipment because the device lacks an X-ray source and detector. There are, however, apps used by professionals for this purpose. view Images already generated by real equipment — which is quite different from producing the exam.
Can the app see through clothing or walls?
No. The camera only captures the light that reaches it, and clothing and walls block that light. Everything that appears on the screen is an image stored within the app, always the same, regardless of where you point it.
Are these apps harmful to your phone or your health?
They don't emit radiation, so there's no health risk. The only inconvenience for the device is the ads and the space they occupy. The real concern is excessive permissions: only install what's published in official app stores and avoid individual installation files from unknown websites.
Can I show the app image to a doctor?
That doesn't make sense. The image is generic and has no relation to your body. If you have a symptom that is worrying you, the best course of action is to consult a doctor and, if necessary, have an examination requested by a professional.
Conclusion
The "X-ray app for your phone" is a joke, nothing more. The five titles we've listed are published on Google Play, are free, and display ads, all delivering the same thing: a visual effect designed to make those unfamiliar with the trick laugh. None of them capture, analyze, or diagnose anything—even when the store listing doesn't mention it, as in the case of x ray scan v3.0, or places the app in categories like Tools and Education.
Reinforcing what this text begins with: These apps are not a substitute for imaging exams or consultations with healthcare professionals.. If you have persistent pain or suspect a fracture, seek medical attention—either through the public or private healthcare system—and leave the pranks for a more relaxed moment.
