Quick Plumber is a free Android app developed by Qbiss under the Business & Productivity category. It is a tool designed to help all plumbing professionals, including plumbers, plumbing apprentices, and plumbers' helpers, perform their tasks quickly, simply, and reliably.

The app features a simple pipe offset calculator that finds your travel piece for 60°, 45°, and 22.5° offsets by multiplying the offset by fitting constants and subtracts your optional takeoff, which is automatically multiplied by 2. Additionally, the Rolling Offset feature finds your travel piece by squaring the offset and the rise, adding the two numbers, then square rooting and multiplying the results by fitting constants. The app also allows you to add or subtract all in standard measurement format feet, inch, and fraction of an inch.

It's important to note that Quick Plumber is not responsible for any errors and rounds to the nearest +-1/8. This app is an essential tool for plumbing professionals looking to perform their tasks quickly and efficiently.
