According to wikipedia: An inclinometer or clinometer is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator. follow us on facebook,skype or twitter
1) Real time display angle value reference by horizontal axis.
2) 2 mode for using(mode 1 and mode 2).
3) Graphics Animation display related by mode.
4) Display 0 to 90 degree reference by horizontal axis.
5) Calibrate option for accuracy.
This app measures the angle and the slope of an object. This free version includes two basic protractors.
1. Touch Mode : for angle. After putting an object on the screen, touch the screen.
2. Plumb Mode : for slope. This mode uses a weight and a vertical line.
* Pro version added Features :
- Ruler was integrated.
- ProtractorⅢ, Surface level
- Various Tilt units
- No ads

If you UPGRADE to pro version:
You can save the measurement data and then email it.
Pro version is ad free.
How To Use Protractor (see attached pictures)
Step 1: An angle has two rays. Put the phone on the first ray, press the "START MEASURE" button. The displayed angle value is reset to 0.
Step 2: Locate the second ray, and put the phone on it. The measured angle will be displayed in the unit of degrees. Assuming that in step 1 the phone is in a plane, in step 2, make sure that the phone is either in the same plane or in a parallel plane.
How To Use Angle Gauge (see attached picture)
Go to setting page and enable angle gauge. Put the phone on the surface to be measured. The displayed angle value is the angle from the measured surface to the ground level.
For both protractor and angle gauge, calibration makes measurement more accurate.
1. When measuring angles in a horizontal plane, with magnetic sensor used, metal objects nearby can cause measurement inaccurate.
2. The shape matters. Phones with round edge or uneven bottom could generate less accurate results.
Colored text boxes show you which values you entered while the white one's show the calculated values.
On Screen Keyboard makes entering values easy and fast without the android keyboard popping up and down to get in your way.
No need to hit calculate because after every key press the calculator will solve for the missing values if enough information is available saving you time and key presses.
Thanks to the following people for helping me make it better:
The height of a object can be determine by estimating the distance to the object (or by determining the distance to the object on a map by simply touching the map) and pointing the viewfinder at the bottom of the target and then the top of the target.
The distance to an object can be determine in several ways: by estimating the height of the object, by triangulation from two points, or by pointing to the object on a map.
The power of our application is that the information can not only be shared with various social sites such as Facebook, e-mailed to others, but also synchronized to a website we allow you to create so others can see your work. Through the website, the data can be viewed in real time by friends, family and/or colleagues. The synchronization also serves as a way to back up your data should your phone or tablet malfunction in the field. If you do not have web access, the application will collect the data and store it until a web connection is established. Once the data has been uploaded, you can edit the data, create reports and/or maps, and download the data or reports to spreadsheets and other documents. Once your surveying or measuring is completed, you can automatically create a powerpoint or video of your work. Try it, it is free. You can also access the data via our website at www.majorforms.com.

I'll integrate more tools. Do you want to get more tools and features? Please send an email. firstname.lastname@example.org
I hope my apps are useful to your SMART Life. Thank you.
** No internet support : You can open this app without any connection. After installation, open the app 2-3 times with your device connect to WI-FI or a 3G/4G connection.
** This app does not support the devices that have NO magnetic sensor (e.g HTC Desire V, ST21i, Micromax).
** Remove and freeze adBlock app. It causes the licensing failure.
** Google has recommended this app as one of the essential apps of Google Play for Education.
Is It Straight measures the tilt angle of any object in front of you, and helps you align objects horizontally, vertically or at any angle.

Standard Level (w/ Camera):
-Use the camera to level a picture, or tell what angle an object is at
Standard Level (without Camera):
-Use the phone as a regular level, or measure the angles of surfaces
-Laying a phone flat on a surface, you are able to get the each respective angle (of the x and y access)
Angle From Image:
-Using the camera you are able to freeze an image, mark the end points and angle of an object to tell the angle created.
*Note this tool should not be relied upon when accuracy is important. The accuracy can be greatly affected by the quality of accelerometers in a phone and any current vibrations, as well as differences in camera qualities*
This app helps you measure camber and caster angles of your RC model.
1. The angle displayed is always less than 45 degrees. (ie, 4 degress instead of 86 degrees, and 2 instead of 92)
2. It is possible to quickly set zero orientation and measure angles relevant to this zero. (if position of setup board is not absolutly horizontal, and the sensor is not always working perfectly.)
3. Adjustable speed/accurancy.
• To measure a viewing angle of the object, azimuth or slope of the object using the camera on your phone
• To adjust your satellite dish (the software enables display both azimuth and elevation). To confirm a direct visibility to the required point on the sky (i.e. to detect barriers for the signal such as trees or buildings)
