Mobile Scale is a unique app that allows you to measure or estimate the mass of objects without the need for a physical scale. Developed by Takács Viktor József, this app harnesses the principles of elastic collision in physics to calculate the unknown mass of an object.

The process is simple. First, install the Mobile Scale app on your Android phone. Then, calibrate the app by typing in a known target mass. When the LED indicator is on, carefully perform a little elastic collision between your phone and the object you want to measure. If the mass of your phone is accurately estimated, you can proceed to measure the unknown mass using the same process.

It is important to note that the author is not responsible for any damage to your mobile device, so it is recommended to wrap your device carefully before calibrating or measuring. Additionally, it is advisable for children to use this app under parental supervision.

Mobile Scale offers a fun and educational way to explore the principles of physics while measuring mass without a physical scale. Download the app today and start measuring with your mobile phone!
