Smart Measure Pro

This application is a range-finder, also known as a telemeter, that uses trigonometry to measure the distance, height, width, and area of a target. It is a simple and easy-to-use tool that requires the user to stand up and press the shutter button on their camera. However, it is important to note that the camera must be aimed at the ground, not the object, in order to get accurate measurements. For example, if you want to measure the distance from someone, you would aim at their shoes.

If the measurements are not accurate, the user can refer to the instructions and checklist diagram on the developer's blog. The app also has a calibration menu for users to adjust and personalize the measurements for their own use.

The pro version of the app offers additional features such as no ads, the ability to measure width and area, portrait mode, and camera zoom. There are also three different tools for measuring distance: Smart Ruler for short distances (1-50cm), Smart Measure for medium distances (1-50m), and Smart Distance for longer distances (10m-1km). For those who want even more tools, there is an option to purchase the Smart Tools package.

The app can be used without an internet connection, making it convenient for users to access anytime and anywhere. However, it is recommended to open the app 1-2 times with a WI-FI or 3G/4G connection after installation. For more information and tutorials, users can watch YouTube videos and visit the developer's blog.

This application is a one-time payment, meaning users only have to pay for it once. It is a useful and practical tool for anyone who needs to measure distances, heights, widths, and areas accurately and easily.
