OffsetKit: Pipe Calculator

OffsetKit: Pipe Calculator is a practical Android application designed for professionals who need to quickly calculate simple and rolling pipe offsets without distractions. This tool transforms your measurements into clear pipe axis geometry, allowing you to verify results before cutting or installing materials. It supports both imperial fractional inches and metric units, making it versatile for various regional standards and project requirements.

The interface is built for efficiency, featuring clear illustrated diagrams that help users understand the geometric relationships involved in complex piping configurations. The app allows you to calculate simple offsets, providing values for travel, run, and shrink. For more complex tasks, it handles rolling offsets, displaying true offset, travel, run, and rotation.

Users can select from common bend angles or enter custom angles manually. A useful feature is the ability to save calculations with custom short names for future reference, ensuring that your most frequent configurations are always at your fingertips. The interface includes detailed information for every calculation, helping you maintain accuracy in the field.

OffsetKit offers three display modes: light, dark, and high-contrast, ensuring comfortable use in any lighting condition, whether you are on a bright construction site or in a dimly lit basement. If you need the length of a straight connecting element, you can access the connector deductions section. Here, you can input start and end offsets, as well as start and end gaps.

Each value is treated as a deduction along the diagonal connector, with OffsetKit subtracting only the entered values while keeping the main offset geometry visible. This app is ideal for pipefitters, plumbers, HVAC installers, and craftsmen who frequently work with pipes. It is perfect for those who value speed, precision, and autonomy in their tools, especially since it works completely offline.

The main advantage of OffsetKit is its total privacy and autonomy. All your data remains on the device. There is no advertising, accounts, analytics, tracking, cloud sync, or internet permissions.

Saved calculations and settings are stored locally, and backup is disabled. It is important to remember that OffsetKit calculates only geometry. It does not apply fitting tables, pipe charts, bend development, pressure rules, welding prep, building codes, or manufacturing tolerances.

Travel is the diagonal length of the pipe axis between bend centers and is not an automatic cut length. Always verify entered data, deductions, field dimensions, and technological practices before cutting or installing material. This APK is a reliable companion for precise pipe work.
