Wrist Beam Menu Bar

Put Garmin Body Battery in your Mac menu bar

Problem

Knowledge workers sit in front of a Mac for hours; devices have battery bars, but people don't. Garmin Body Battery, stress, and heart-rate data are locked in a phone app, and reaching for the phone breaks focus. Developers want to glance up and see how much energy they have left.

Solution

An open-source macOS menu bar utility that connects directly to Garmin watches over BLE and shows Body Battery, heart rate, and stress in the menu bar and a popover, with gentle alerts when energy is low or stress is high, plus a simple health dashboard.

Users

Garmin watch owners who are knowledge workers or developers spending long hours at a Mac.

MVP

Menu bar display of Body Battery and heart rate; BLE pairing without a phone; notifications for low energy or high stress; simple 7-day trend chart; open source with community device adapters.

Revenue

Free open-source core; Pro version with advanced trends, multi-device support, and custom alerts via one-time purchase around $15.

Why now

Wearables are mainstream but official desktop experiences are missing; developers have already reverse-engineered the BLE flow with AI, so a solo developer can deliver a polished native Mac tool now.
