Comments on Ruler App: Measure centimeters for Android
★★★★☆Robert Greene· Sep 8, 2025
Yes, now your phone can measure things. Great to have a ruler. Update ruler is now off true measurement it should be calibrated at 5 inches not 1 now with adds. Update 9-08-25 calibrated with Credit card now working.
★★★★★John Harley· Dec 31, 2025
Very handy. I've had this app for 6 years and still a great app whenever I need to measure.

I've been using it quite a while now as a ruler on my phone. Tbf. I use it frequently to measure real life objects and have found it to be practical and useful 👌🏾
★★★★★Erik Gentzel· Aug 11, 2025
Simple app, does what you think it does, and isn't obnoxiously loaded with ads, or gated behind a subscription. I also checked the measurements with a real ruler, and they match up very precisely with less than 1/32 inch error. No complaints from me!

It does what it needs. Forcing ads and downloads isn't worth it. I'll just stick to trusty tape measuring
★☆☆☆☆Shane Colon· Dec 7, 2024
Another phone sized ruler. Completely useless!
★☆☆☆☆Rahman Khan· Apr 11, 2026
These apps doesn't work, it's just a waste of time, you can download other apps
★☆☆☆☆Jeff Smith· May 23, 2026
Requiring installing another app or charging $$ for a simple dark theme is ludicrous. Uninstalled.
★★☆☆☆MR. PRANJAL NEOG (PRAN)· Jul 15, 2026
Not that bad. May be needed some more improvement
★☆☆☆☆Samuel Joseph· May 24, 2024
Full page video ads pop up spontaneously, and it makes the app hard to use.
