Distance Ruler - meter distance.
It works like this: you set the height of the horizontal plane (eg from the floor in the room), which is an object (eg a wall), to your phone's camera (advised to measure the height of your eyes and use it, hold the phone camera at eye level), then aim the camera at the intersection on a horizontal plane and the object (the angle at half-wall) and see the right-bottom of the object distance.
The program gives the distance to the object (before crossing the floor and wall), counting the rectangular triangle known one side of the triangle (the height of the camera, you have entered), and 2 of the angle (one - 90, the second program says phone position sensor in space). Picture illustrating this triangle can be found in Help. If you stand on a chair and try to measure the distance to the wall, you get an incorrect result, since the height of the camera changed.
Now the interface: the top button changes the unit of measurement (TRS>cm->m->km); bottom 3 buttons: the camera with a question - help (ENG); Pressing the inscription Ying Wen Technologies sends to the market; camera with a pause - take a screenshot (anyway, that touch on the screen). Above are 3 more buttons: Camera Hieght - height of the camera (click on it to enter the height of the camera phone); button which freezes the measured distance (numbers not to jump); Aim Distance - the distance measured.
