Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

User's Reivew

1 ★Cannot calibrate precisely. No option to calibrate based on screen dimensions whatsoever. Default calibration is incorrect at every screen resolution setting. You'd think "enter dimensions of your screen" or "enter your screen diagonal length" would be an option, but no. Only rough approximations are allowed. Rip no thank you.

5 ★It's just a ruler. No gimmicks, no in-app purchases. Nice to have fractions of an inch.

5 ★Great! The only thing that would make it better is if the camera was attached and you could measure real things through the camera!

5 ★This app worked really well! Calibration was a breeze using a coin from my pocket.

3 ★Very simple and straightforward but it's really hard to get out of. In my Android phone the bottom menu disappears and it's hard to get it back so that I can back out of the app

5 ★Looks nice, works great, dead-simple calibration process, no ads, and no unnecessary permissions. The perfect package!

5 ★Good app good measurement display choices great anytime u need a ruler minus or course the fact that your phone is still ur phone (can't put edge up to things) just saying this would be difficult to measure out something prescice physically in some situations, but it helps you get an idea of what would work and what your looking at.

5 ★Easy to use and very accurate. One annoying feature: I would like to see a setting to prevent the display from rotating when I try to measure an object. I think this is possible instead of having to go to phone settings to turn this off and then return to set rotation again.

5 ★Great app, shows correct data, whilst still being AD free and with a great and intuitive interface :)

5 ★No ads, can be also calibrated using credit card

3 ★When i will sketch 1 inch in my paper, my finger somehow touches the screen even the paper is underneath it, i tried with an illustration board but its still the same, would be better if you put a lock on the side of the screen, its also a good app.

5 ★What a great app. During this time of Covid my daughter is doing her 2nd grade schoolwork at home. Couldn't find a ruler for her to do her homework, and this app was amazing. Perfectly calibrated.
