## Description

O-Ring Groove Calculator is a local utility for mechanical engineering, equipment repair, mold assembly, and DIY sealing projects. Use it offline to look up common O-ring sizes, calculate recommended groove dimensions by inner diameter, cross section, and groove type, and check whether compression, stretch, and fill rate are within reasonable ranges.

The app requires no account, does not connect to the internet, and does not collect any data. It is designed for one-time purchase and long-term field use. All projects, favorite sizes, and calculation records stay on your device for repeated offline reference.
