In this the limited but therefore free version of Clinometer. It as all features but can not be calibrated. This professional tool called Clinometer is the most precise (all you can get with some calculations) slope measurement tool for the iPhone, iPod Touch and iPad. It can be used for simple applications like aligning a frame as well as for more sophisticated fields of applications where an arbitrary slope needs to be measured exactly. Read the reviews (and write your own) for all the applications you find! Thank for all your positive feedback! Please use our support link if you have questions and suggestions, we don't read the iTunes reviews every day. With this tool, the slope can be measured by all edges of the device in every direction. When the device is put flat on the table a bubble view will fade in. The current features include: ◆ Five different unit modes: The device can display the slope in degrees (rounded or in tenth of degrees), percentage, rise over run (common for roof slope measurement in :12) and 1V:H (common in engineering) ◆ Dial Rotation: You can smoothly rotate the background dial and thus define which side of the device represents 0° and 90° degrees. ◆ Motion-sensitive Lock feature: Besides the common instant simple tap hold mechanism you can activate the motion-sensitive lock. If activated the device waits for the final lock until you hold your device steady enough for at least 2 seconds. You can set the lock sensitivity between 0.1° and 1.0° degrees. ◆ Volume Button Lock: Use volume buttons to trigger the lock. ◆ Peer Mode: Use two devices to measure angles: One as a display, the other as the measurement device that can be attached to the hardware you want to align. ◆ Fullscreen Mode: The full screen mode can be toggled by tapping the center of the screen and by the upper and lower arrows in the center. This prevents you from erroneous inputs while measuring. ◆ Different color schemes: Press the S/C Button to instantly switch the color. The color can be selected differently for the bubble and the clinometer mode. The predefined color sets include day and night color schemes (Black on White, White on Black and Red). ◆ Adjustable Auto-Lock: You can prevent the device from turning into the sleep mode. Only the full version has a two way calibration feature! Please support us and buy the full version if you can. 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. For recreational use only. After the calibration it CAN (!) be very accurate especially for the main axis after calibration. The measurement is performed as well as possible (we try our best) by using the three inbuilt accelerometers. THANK YOU FOR YOUR SUPPORT! We will improve the application long-term. This was the first application of this kind shortly after the opening of the App Store. Since then it is continuously updated and enriched with new features. ► Check out all our products (free and paid) on www.plaincode.com

About

Digital Angle Finder

Measure angles precisely using your device's sensors. It functions as both a protractor and a 3D angle meter, allowing you to determine angles between surfaces or lines on a plane with high accuracy. Save your measurements by taking photos with the angle recorded.

Highlights
  • Precise angle measurement
  • 3D angle measurement
  • Protractor mode
  • Save measurements with photos
  • High accuracy (1-degree error)
Read full description

Digital Angle Finder is an app for precise measurement of angles, simply by moving your device. The "Digital Angle Finder" app measures the angle of the device, using the accelerometer and gyroscope. Just place your device against two surfaces in turn and "Digital Angle Finder" will give you the angle between them. In the protractor mode you can also determine the angle between lines on a plane: in order to do so align the edge of your device alternately against the sides of the angle. The accuracy of angles measurement is rather high: the error is only one degree! You'll appreciate the ability to save the measurement by taking a photo with the measured angle recorded on it. We are sure that you will like the design of this app. Digital Angle Finder is an app that adds a new feature to your device which you have never imagined!
