SeeLevel vs Angle Meter 360

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.

Easy and user-friendly angle meter. The application allows you to measure angles on the pictures, photos or from the camera in real time. With Angle Meter 360 you are able to permanently measure unlimited number of angles. Due to the addition of new tools or deleting old it is possible to receive and compare information from several angles at once. Scaling, moving the object and the possibility of changing of instrument's color allows you to measure angles easily, fast and accurately. Functions: -angle measurement on the pictures and from the camera - measurement unlimited number of angles simultaneously - the possibility of scaling and moving the object - adjustment of the color of tools for visual convenience. Easy and user-friendly interface allows you to determine the angles very fast and accurately. You only need to place the tool on the contour of the object and you immediately receive the result.
