To calculate or estimate a distance between two objects or locations using:-
1. Camera
2. GPS/Network

How to calculate distance using Camera:-
1. Hold up your phone in Landscape orientation and estimate the phone's distance from ground.
2. Then aim the camera at the object which you want to calculate the distance.
3. The target should be at same ground level from where you're standing. If not, you need to do some adjustment.
4. You must aim at the BOTTOM of the object. (Eg: If a building, aim at the bottom of the building. If people, aim at the feet. If a car, aim at the tire)
5. ROTATE the phone when you try to aim the target. DO NOT move the phone UP/DOWN from the phone's height which you have specified earlier.
6. Tap the screen to stop the calculation or re-tap to continue.


How to measure distance using GPS/Network:-
1. Get the coordinates when you are at Location A.
2. Then move/walk/drive to Location B and get the second coordinates.
3. When you have the coordinates for both locations, the app will auto calculate the distance.

The app will first try to get the coordinates using GPS. If not available, it will use the Network. Accuracy and speed will depend on the provider.

This app can only act as an estimator or for quick calculation. It will not give you 100% accuracy.
计算或估计两物体或使用地点之间的距离： -
1。相机
2。全球定位系统/网络 如何来计算距离，使用相机： - 1。托起您的手机在横向和估计手机的距离，从地面。 2。然后相机瞄准的对象，你要计算的距离。 3。目标应该是在相同的地面，从你站在那里。如果没有，你需要做一些调整。 4。你必须着眼于对象的底部。如果建筑物，目的是在建筑物的底部（例如：如果有人在脚上的目的，如果一辆车，在轮胎的目的。） 5。旋转手机，当您尝试瞄准的目标。不要移动电话手机的高度，你前面指定向上/向下。 6。点击屏幕停止计算或重新点继续。 如何测量距离，利用GPS /网络： - 1。得到的坐标位置答：当你在 2。然后移动/步行/驾驶位置B，并获得第二个坐标。 3。当你有两个位置的坐标，应用程序将自动计算距离。 该应用程序将首先尝试利用GPS的坐标。如果没有可用的，它会使用网络。精度和速度将取决于供应商。 这个程序只能作为一个估计或进行快速计算。它不会给你100％的准确率。
