Convenient and easy to use, Moasure is a 300m/1000ft tape measure, ruler, protractor and a goniometer (angle measurer) - all in one simple app.

Simply move your phone from one point to another point and Moasure displays the distance or height difference between the two points, or the angle between them.

Top 10 in overall App Store in 101 countries.

There’s no tape, no string, no laser beam or camera images. Instead Moasure uses the same technology found in space rocket guidance systems – the iPhone’s accelerometers and gyroscopes – to calculate precisely how far you have moved your phone. Moasure really is rocket science!

Moasure can measure the length, width, and height of objects, as well as internal room dimensions and even inter-room dimensions.

In fact, there’s not much that Moasure can’t measure.

• Measures distances from 10cm to 3000m (4” to 1000ft) quickly and easily.
• The only app that retains its accuracy for distances greater than 10m/30ft, thanks to Moasure’s unique multi-step measurement mode.
• 5 different measuring modes for measuring objects, spaces, height difference and angles.
• Measures round obstacles as if they weren’t there - great for measuring room dimensions.
• Label and save measurements for future reference, printing and sharing via SMS or email.
• Displays in metric or imperial units.
• Measures the angle between two lines or surfaces.
• Distance accuracy better than 1% accuracy on iPhone 7 and 2% on iPhone 6. Angle accuracy better than 1 degree. (Watch the help videos for tips on achieving the best accuracy.)

IMPORTANT: Moasure has not been designed for use on iPad, because of its size. Please be careful when using an iPad to take measurements.

A simple app on your smartphone, Moasure is available whenever and wherever you need it. No Internet connection is needed, and there’s no need to hunt through a toolbox or kitchen drawer for a ruler, tape measure or a laser. You’ll never find yourself without a tape measure.

You don’t need someone to hold the end of a tape measure, just move your smartphone from A to B and let Moasure do the rest. The measurement will be displayed on your screen instantly.

Moasure can measure almost anything, from the width of a tile to the length of your garden. If there’s something in the way, like a wall, just walk round it and Moasure will measure straight through it.

Moasure is a serious measuring tool, suitable for use by professionals. It‘s ideal for estimating dimensions when quoting for jobs. (However, please don’t use Moasure when measuring to cut or drill material – it isn’t accurate enough to do that just yet.)

Moasure uses patented technology to get the most accurate and consistent results of any motion-measuring app available.

The accuracy of the measurement depends on the iPhone model, and the time it takes to complete the measurement. A visible and audible timer indicates when the accuracy starts to deteriorate.

For even greater accuracy, you can repeat the measurement a number of times and Moasure displays the average measurement.

We’ve taken thousands of test measurements, covering all the different iPhone models, and in our experience, you should be able to achieve an accuracy* of between 1% and 3%, depending on your individual phone.

If you require greater measurement accuracy, please see Moasure ONE at

*Results are for measurements taking 2 to 3 seconds to complete. Measurements over a shorter period should be more accurate, whilst longer measurements will be less accurate. When using multi-step measurements, the accuracy is determined by the time period for each measuring step.

Very good but.......

Honestly I'm impressed and this is very handy if you want a measurement that doesn't really require spot on accuracy. I'm not saying it's not accurate, not at all, it's impossible to have a spot on measurement with your standard tape measure all the time, hence the wording "all the time". But this tape measure app is very good if you're getting measurements quickly on the fly, or trying to get all the measurements during your quote at a job site, or impressing your buddies with your new state of the art tape measure....... bottom line is, this is worth every penny, please be patient, watch the videos on how-to, trust me, I didn't the first time and didn't like it, after watching it and getting familiar with the app, I'm here writing about it aren't I? :-)

Hi Deaf fox,

Thank you for your kind review! We have some updates coming soon which will improve the accuracy and make the app easier to use.

Best regards,

The measurements seems to change a bit after measuring the same distance multiple times. Also the measurements may be slightly off which I have already read about on the website.

The worst device I’ve ever used

First off good luck on finding an app to download all apps are geared towards selling more services that are worthless.
I was able to get it to measure a couple of very small areas but would not save any other measurements greater than a few hundred feet.
The device would lose connection and would have to start over several times before I just went back to using google earth.
Don’t waste your valuable time on this worthless gadget that will stay in your glove box and tossed in the trash after a few months.
