Shifty

A native macOS menu bar app that nudges you to change posture throughout the day, rotating between standing, sitting, and any custom positions you add on a configurable, randomized schedule, with notifications at each change.

Install

brew tap human37/shifty
brew install human37/shifty/shifty
brew services start human37/shifty/shifty

Install (local development)

brew install --HEAD ./Formula/shifty.rb
brew services start shifty

Service management

brew services list | rg shifty
brew services restart shifty
brew services stop shifty

Configure options and interval

Shifty writes config and runtime state here:

~/Library/Application\ Support/Shifty/config.json
~/Library/Application\ Support/Shifty/state.json

Default config.json is:

{
  "options": [
    { "label": "STAND", "icon": "🧍" },
    { "label": "SIT", "icon": "💺" }
  ],
  "intervalMinMinutes": 50,
  "intervalMaxMinutes": 70
}

To add more options or change interval:

1. Add options from menu: Options -> Add Option... (saved automatically), or edit config.json directly.
2. Restart service: brew services restart shifty.

state.json persists current option, queue, and next-change timestamp, so after restart/login Shifty resumes the same option and same time window.

Publish a new version

• Create and push git tag v0.1.1
• Create a GitHub release (if missing)
• Update human37/homebrew-shifty formula url and sha256
