SeeLevel vs Offline Inclinometer

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. USER FEEDBACK: 
Simple, effective and finally offering a clinometer with percentage. Very good, I can recommend it. 
Piwilari, France It is easy to use and effective for many types of measurements (angle, height, distance). The interface is uncluttered and very clear. Good job. TychoMoon, France 
Very good idea that works very well. angor69, Italy 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. Top Tier, USA NOTE: Requires a device with a camera. i.e. compatible with all iPhones, iPod Touch 4 and iPad 2.

This app was made by Hopebest Limited. It can help you measure how steep the slope of a mountain/trail is. Simply adjust your phone so that it is parallel to the slope you are on and it'll let you know how steep/the angle of the slope. An Inclinometer app is an invaluable digital tool designed to measure angles of slope, elevation, or inclination of an object with respect to gravity. Originally developed for geology and engineering purposes, the utility of this app has expanded to various fields including construction, automotive, and even smartphone photography. Using the internal sensors of a device, such as gyroscopes and accelerometers, the app offers a high degree of accuracy in measuring angles, making complex traditional tools like physical inclinometers or spirit levels nearly obsolete in everyday use. The interface of an Inclinometer app is typically user-friendly and intuitive. Upon opening the app, users can calibrate their device against a known flat surface to ensure precise measurements. The main display then clearly shows the angle measurements, often in degrees. In essence, an Inclinometer app transforms a smartphone or tablet into a multifunctional measurement tool, combining convenience, precision, and versatility. This makes it an essential digital companion for both professionals and hobbyists who require accurate inclination readings in their work or daily life.
