Your search for a perfect mobile clinometer, protractor app for measuring angles and leveling surfaces ends here. Our clinometer, spirit Level, protractor, bubble Level - Multitool is extremely precise and intuitive to handle.

These intuitive features are packed in the Measure App level tool with easy user controls and intuitive handling.

■ 360° clinometer ■
Use the clinometer the measure angles along all edges of your phone. You can set a target angle by moving your finger across the display. Additionally you can store up to 5 angles in the angle list and recall them quickly as target angles.
Approaching the target angle or the 90°/180°/270°/270° angle (according to your setting) you can receive different acoustical warning depending on the difference between measured and targeted angle.
Protractor-Multitool also features a stability indicator indicating the rate of change.

■ Spirit level ■
Approaching 0°/90°/180°/270° a spirit level is displayed. This enables you to precisely level things.

■ Surface level ■
The surface tool enables you to level surfaces. Level differences will be displayed in degrees.

■ Intuitive ■
Depending on the orientation of your iPhone the view transitions from surface level to 360°-protractor.
In addition to that spirit levels will be displayed when approaching cardinal angles.

■ Highest precision ■
The 6-point calibration assistant guarantees high precision up 0.01°.
Surface level and protractor calibration are completely independent of each other allowing for even higher precision.

■ Sophisticated design ■
Measure App native drawing capabilities of your phone for extremely clear and fluid display.

Digital level (level tool, bullseye level, pitch & roll indicator, surface level)!

We put the machinists level on the lathe when setting it up, I put my phone on the lathe to see if it would be close to the machinist level and as we leveled it up my phone stayed with in a half of a degree, I was impressed with how close it was

Used for a completely different purpose

So I’m an amateur astronomer. Your thinking ...why are you here. Well this app is amazing because it shares compass bearings and the inclinometer helps me find celestial objects in the night sky. I have my phone attached to my scope facing true north at 0 degrees inclination for calibration and I am able to swing my dobsonian telescope and angle it with reasonable accuracy. Usually within a degree or 2 in compass and inclination. While that’s a bit high error rate for more serious astronomers it works just fine for me to get a general sense of the target I’m searching for. My only recommendation from a purely selfish point of view is to have an option to show compass bearing on the same page as the inclinometer without having to switch between the 2 modes.

Great backcountry ski tool

Just what I was liking for. Most clinometers require you to match the angle with the edge of the phone as you look at it. It’s also how mot handheld tool work. The problem is you have to be ON the slope and thus already in danger for that to work. In his excellent avalanche safety book, Bruce Tremper recommends using a mirror compass with a clinomètre that lets you sight downslope. The problem with that is the numbers are hard to read at arms length, are backwards and are off by whatever declination you have adjusted for which, in my area, is about 13 degrees. This app solves all those problems. You can use it on the slope sighting across, but you can also sight down a slope, double tap, and it saves the angle so you can read the number easily. Perfect for what I want.
