Multi Angle Meter vs LinkRay Scanner

INSTRUCTIONS When the iphone is tilted, the tilt angle is displayed in the three axes of yaw, pitch, and roll. Long-tap the number of an angle degree on the screen: The angle is set "On the ground" is displayed in the upper left corner of the screen.　 Double-tap the number of an angle degree on the screen: The angle is reset and "On the table" is displayed in the upper left corner of the screen. Each time you double-tap, the angle is reset. Long press the number of an angle degree on the screen to initialize the angle. The angle based on the ground is displayed. "On the ground" is displayed in the upper left corner of the screen. Setting: You can set the angle notification function. *Screen Description On the ground: Default value. Displays the angle to the ground. On the table: Displayed when the angle is reset. Yaw: Rotation angle of the horizontal plane with the vertical axis. If the Angle Notification function is set to On, the angle will be displayed in red from ±2 degrees of the set angle. If Vibration is set to On, The angle is displayed in red letters with vibration. Roll: Angle of rotation on the front-back axis. If the Angle Notification function is set to On, the angle will be notified in orange from ±2 degrees of the set angle. (If Vibration is turned on, The angle is displayed in orange letters with vibration. Pitch: Angle of rotation on the left/right axis. If the Angle Notification function is set to On, the angle will be notified in green from ±2 degrees of the set angle. (If Vibration is turned on, The angle is displayed in green letters with vibration. Tap the Stop button to stop the measurement; tap the Start button to resume measurement. Tap the camera button on the screen to activate the camera for the live view screen. Tap the screen while the camera is paused to display angle guides (protractor lines). You can add up to five. Setting: Displays the angle set by the angle notification function on the Setting screen.When the toggle button is turned on, the color of the numbers changes from +/- 2 degrees of the set angle.If you turn on the Vibration and Sound buttons, you will be notified with vibration and sound .You can choose to display the angle as an integer or a decimal. Note: The angle displayed is the angle detected by the gyro sensor of this iphone. To measure the angle accurately, use a calibrated angle meter or inclinometer instead of this application.

LinkRay Scanner reads LinkRay (HikariID) optical IDs transmitted by LED lighting. Point the camera at a participating light, and the app decodes the ID that light is broadcasting and shows what it is linked to. WHAT IT DOES - Decodes LinkRay IDs from LED lights using the rear camera - Looks up each scanned ID and opens the content mapped to it - Keeps an on-device log of what was scanned and how the camera performed - Uses a published camera profile for your iPhone model HOW IT WORKS A LinkRay light carries a short numeric ID by flickering faster than the eye can see. The app samples that flicker through the camera and recovers the ID. Recovery depends on the precise timing of the camera sensor, so the app relies on a camera profile published for your specific model. WHAT YOU NEED - A LinkRay-equipped light to scan - A network connection: the app loads its screens and the content for each scanned ID from the LinkRay Scanner server - A published camera profile covering your iPhone model ON MEASUREMENT This app decodes using camera profiles that already exist. It does not measure or calibrate new profiles. PRIVACY Video from the camera is processed on the device and is never uploaded. Diagnostic records of a scan - your device model, decode timings and the result - are sent to the LinkRay Scanner server so that profiles can be improved. The privacy policy at https://linkrayscanner.piecefuture.duckdns.org/privacy explains what is kept and how to have it removed.
