Гибка is an Android app developed by SergeD that serves as a calculator for computing the full length of sheet metal bending with a 90-degree angle. This tool allows you to input values for metal thickness, bending radius, and profile dimensions. The metal thickness ranges from 0.1 to 20 mm, while the bending radius varies from 0.1 to 33 mm. The app also includes various profiles such as angles, channels, and C-profiles. In addition to the 90-degree bending, there is a menu for calculating bends with angles other than 90 degrees.

The user interface of Гибка is straightforward and user-friendly. It is easy to navigate, and the input fields are well-organized, making it simple to input the required values. The app is free to download and use, making it an excellent tool for metalworkers and fabricators who need to calculate bending lengths quickly and easily.
