Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 7.88 MB, so it installs quickly even on modest connections.
This build is signed by "SECUSO - Security Usability Society" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Privacy Friendly Tape Measure can measure the size of objects in pictures based on objects of known sizes (e.g. coins) in the same picture. Just find a coin or other reference object of a known size, put it next to the item you want measured and take a picture. Make sure all objects are in the same level and the picture is taken perpendicularly to it. Now you can mark the reference object in the picture and measure any length or area you want!

Privacy Friendly Tape Measure belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Institute of Technology. More information can be found an https://secuso.org/pfa

Privacy Friendly Tape Measure can also display rulers or a protractor on the screen. Use this to quickly measure small objects or to cut a pizza in six equal slices. Yum!

What makes Privacy Friendly Tape Measure different from other similar apps?

1. Fewer permissions
Privacy Friendly Tape Measure uses only the Read External Storage permission. It needs it because most pictures on your phone are located on the SD-card as opposed to the internal phone memory.

2. No advertisement
Many other free apps in the Google Play Store dazzle you with annoying advertisements which also shorten battery life.
