## What it is
A macOS application that turns a MacBook's Force Touch trackpad into a digital weighing scale by reading private pressure sensor data. It uses a custom fork of the Open Multi-Touch Support library to access raw trackpad pressure readings and convert them into grams.

## Use cases
- weigh small objects using my macbook trackpad
- turn macbook trackpad into a scale
- measure weight in grams without a physical scale
- read force touch pressure data on macOS
- calibrate trackpad pressure readings against a real scale

## When to choose
- you have a 2015+ MacBook with Force Touch trackpad and need to weigh small light objects
- you want a free, open-source alternative to a dedicated digital scale for lightweight items
- you're curious about accessing private trackpad pressure APIs on macOS

## When to avoid
- you need precise, certified weight measurements for commercial or scientific purposes
- your Mac lacks a Force Touch trackpad or runs macOS older than 13.0
- you're unwilling to disable App Sandbox or run an unsigned application
