Ruler

Wondering how big that beautiful new multi function watch is going to look on your wrist? Likely bigger than you thought when you ordered it. 4.3 cm didn't look so big in the specifications. This indispensable tool keeps things in perspective. Isn't that Kool!

This is a very handy app and should be an addition to everyone's phone that needs to measure something small on the spot. As far as I can see, one improvement I would like to see is the addition of millimeters, along with the already existing inch and centimeter. Sometimes I work with millimeters more than the other two measurements. I'll change it to 5 stars if this change is made.

Works well except that the calibration CAL button is a bit vulnerable and opens up easily when you don't want it to. Would be good to lock it. Otherwise, would have given 5 stars.

Does just what I expected. Been meaning to get something like this. Find a real ruler or tape measure to calibrate this app, just once, and you will never be without a ruler. My Swiss Army phone just learned a new trick.

Would like to have a zero offset setting. This would enable calibation of "0" to the edge of the phone body instead of the edge of the screen.

I fabricate with metal and plastic and wood. This tool is perfect for matching depth in a second. No ads or permissions. This developer is my new favorite!

A handy little app to measure up to 3 inches reasonably accurately. A useful sliding cursor allows more accurate readings. Does the job.

I'm so glad to have found this. Most guys don't know what a real inch is lol

Very easy & quick results. I only would like to have a voice to measurement option.

Simple, no ads. I wish I could switch the cm and inches from top to bottom.

Really Appreciate.

Perfect, and comes in handy when you don't have a tape measure. Was going to calibrate but it was exactly right and didn't need to.

No gimmicks no ads...

I have most of your apps and they're so good I fell I should give you a donation.

Tried 5 other rulers, this seems to be the best one...

I don't like I want the app that should measure by using the camera

Black screen won't even open??????

Great app,must download

Does what it says for me ..great.

Simple and no stupid ads. Thanks guy!

How to use it

Boo boo!!

Would be nice if inches could be switchable between 1/16ths and 1/10ths.

Thank you!!!

Please don't use this app measurement is incorrect

Very handy... Calibration button may be hidden.

Just what I need, perfect. Thanks

very good app help full

IT'S GREAT TOOL! THANKS!

Best ruler. Also free and ad free.

Now if you can get it to work like a tape rule, I'll give it 6 stars ;) oh and BTW it is a rule not a ruler :p

Automatically calibrated. Great for measuring small things you can place on your phone. Requires no permissions.

Really Appreciate.

It shows 1 inch=2.53 cms. In fact it is 2.54 cms. Uninstalled.

No ads, small and simple

free and no ads!

Easy to used, no ads, can calibrate, copy data and info about your display screen.

I confirm that no calibration required on Nexus 6.

Very very accurate
