Prepare your MacBook with TrackWeight running and the item you want to weigh.

When you place an object, the TrackWeight screen displays '182.0 grams'. When measuring the weight, you also need to keep touching a part of your body, such as your finger, on the pressure-sensitive trackpad.

On a regular digital scale, it showed 180 grams. TrackWeight's accuracy is not that great, but it's enough to get a rough idea of the weight.

If you have a MacBook with a Homebrew environment, you can install TrackWeight with the following command.
[code]brew install --cask krishkrosh/apps/trackweight[/code]

TrackWeight was developed using the trackpad event monitoring library ' OpenMultitouchSupport ' developed by Takuto Nakamura . The source code for TrackWeight is available at the following link.
