Arrim ONE app together with the Arrim ONE transforms your iPhone into a multi-functional AR measuring device.

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 an estimator… GAME CHANGER!

This will be my first review I’ve ever written for an app. I do estimates for landscaping and this has far and away changed my life. I estimate unusual shapes for sod, concrete, and planting areas all day every day and the tedious rolling the wheel, writing down the measurements, calculating everything at the end- over and over is truly mind numbing. This has changed everything. I measure very odd shaped pool decks, then I measure again, and somehow it can be as little as half a square foot difference over a 600 square-foot pool deck. When I measure twice it’s almost exactly the same. That gives me the confidence to know I’m not messing up. I told my wife if this thing breaks I’m buying 10 more. Sincere thanks!
