About this app

Arrim ONE can be used to measure the dimensions of straight lines, circles, angles and curves. It is also a leveling and dividing tool.

Arrim ONE supports both Imperial & Metric Unit System. You can measure in ft, inch, yard, mm, cm, and m. And you can also choose the maximum precision.

In some cases, ARRIM ONE can achieve the level of precision which is impossible for other tools. For example, if you want to measure the radius of a circle, because you are not sure where the circle centre is, the measurement with other tools may lead to a large deviation. ARRIM ONE can easily solve the problem with an algorithm based on the principle of three points defining a circle.

For the price of this, not worth the frustration. I have to recalibrate the device after just a couple measurements. Most of the time it says to make sure the laser is pointed at something when I'm 5 feet away pointed at the wall or laser unstable when it's perfectly still. Won't buy another one at that price with how it doesn't work properly. It's easier and faster to measure with a wheel and tape measure than to screw around with this ARrim one.

WTH, my phone wasn't compatible, so i ordered one from their list, and the app says my phone is not supported, coming soon, contact support. this is ridiculous. what's the point of having a compatibility list is it doesn't work? it sucks because i really wanted this thing to work. iPhone has an app that works like this device, with out the device. Common guys, get with the program.

App's terms of use are abhorrent. Terms can change at any time, without notice, and users are bound to be terms immediately. Some sort of data is collected by app, data is shared with unknown Third Parties to offer, "services." App requires Location Services and Bluetooth enabled for unknown reasons. If Bluetooth is required for the hardware, what is the USB connector for? To simply hold it in place? Terms of Use conflict with Privacy Policy. Plus the lens on my hardware arrived scratched (or something is stuck to it), charging never completes (or indicator never turns off) and my phone can't connect to the hardware for some reason. I call this a resounding, "NOPE!!!," with regards to App data privacy and disappointing Kickstarter hardware.

Hi, Arrim ONE does not save or share any data. The data mentioned in Service Terms is the order information, and we share it with carrier to complete order. It needs the access to location services because it needs motion sensor data for tracking camera movement. If you have hardware problem, please contact
