Description

Millimeter is a screen ruler app. It uses the full screen of Android devices for distance and length measurements as a caliper or tape measure. Place an object on the scale paper screen and simply touch and move rulers to measure it. Check features for more details. Pro version measures area, circle, radius and diameter, angle, ratio, and splits into equal parts.

NO POP-UP ADS on your screen in the app unlike other free ruler apps on market. The best and real full-screen ruler.

โ˜› ANY DEVICE can be calibrated for accurate measurements in Calibration Mode, where common standard objects (coins, credit cards, etc) can be used as a reference.

v2.3.6

It won't let me rate the regular Millimeter because I paid for Pro. But it is beyond shameful that this company tries to rope people into a subscription for the regular Millimeter app. Subscriptions have gotten out of hand. You have got to be kidding. Pro is available for a one-time purchase, but I don't find it useful. A screen is too small to take useful measurements. It works, just not a must-have. Use a tape measure -- and do not under any circumstances pay for a subscription for one!

Developer Response

Thanks for the honest feedback! We hear you on subscription from the user point, but it helps us to support and keep projects on the market. Quick clarification: Pro is a one-time purchase, not a subscription. You're rightโ€”itโ€™s designed for quick, small measurements on the go, not replacing a tape measure. We appreciate you trying it out.

Almost perfect. It doesn't use the full screen of my phone and the three android buttons are also always visible
