Measure angles and align objects viewed through the camera. SeeLevel also includes a distance/height estimation tool and traceable level.

With SeeLevel you can for example:
- Find the angle relative to the horizon (like a sextant)
- Get the vertical line to the ground (like a plumb)
- Estimate the tilt of objects in the distance
- Calculate the height of, or distance to, an object (Inclinometer).
- The unit of the input and output distances are always the same so you can use any unit you wish (meter, feet, yards etc)
- Use it as a conventional level, independent of the camera
- Zoom in the measured object to improve accuracy
- If your device has a front camera you can use it to measure the level from the ground or use it as an inverted plumb.


Simple, effective and finally offering a clinometer with percentage. Very good, I can recommend it.

It is easy to use and effective for many types of measurements (angle, height, distance). The interface is uncluttered and very clear. Good job.

Very good idea that works very well.

I work for satelite co. and this is 'bout the best visual inclinometer I've come across, and yes my boss does like it, especially on how close the accuracy is compared to a Suunto Tandem.

NOTE: Requires a device with a camera. i.e. compatible with all iPhones, iPod Touch 4 and iPad 2.

What’s New

Version 3.9

- Gradient/ratio as a unit in the Clinometer
- The unit is remembered.
- Fixed a problem when zooming on older devices.

Fulfills needs

This app replaces a $200 clinometer fairly well. I have had a couple glitches, but all in all I am very satisfied

Very handy app

This is a very handy app to have, since most people don't usually carry around a clinometer. The most interesting use is to measure an object's distance when you know it's height, or vice versa. One limitation of using this instead is that you'll usually need to zoom in on the object, and it's hard to hold it steady enough to make a precise measurement. With that in mind, this is still quite useful.

Good Inclinometer Functions App

This app is just what I was looking for. In addition to measuring the angle of the phone, you can use it to measure the height of a vertical object if you know the distance to the base, or you can measure the distance to an object of a know height. The app does all of the trig automatically. You view the object through the camera, and it displays the level horizon on the screen along with the angle or height above or below level. So you can measure the height of an object where the bottom is below your eye level and the top above, just add the two numbers.

If there is one problem, it is that the gyro chip in my 5s seems to not be as accurate with the phone held vertically as it is laying flat. You can calibrate it in the app, but I can't seem to get mine better than about 1.5 degrees. So if you view a distant object that you know to be at eye level, it may show level horizon to be above it. This doesn't seem to ruin the height or distance measurements because the angle error is the same at the top and bottom of the object. But if you need angle from a true horizon, it might not be accurate enough. Maybe the chip in the 6 and 7 are better.
