Name: Sub HUD
Rating: 5 (2 reviews)
Author: A1production

A tactical multi-function display inspired by the dim green glow of an old-style submarine command console. The center sweep arm and pulse dots read like a sonar return; the ammo-bar strips and segmented gauges nod to the brass-and-bakelite era of conning-tower instruments - modernized into a compact ops dashboard for your AMOLED Garmin.

Heart rate, body battery, stress, steps, calories, sunrise/sunset and more - all framed in olive HUD lighting, ready for surface or depth.

What's on screen

Big-readout digital time (12h or 24h, follows watch settings)
Day, date, and month in tactical mono
Heart rate with VO₂max readout
Body Battery and Stress as ammo-bar style 8-hour history strips
Steps + active calories ("active vs total" mode optional)
Sunrise & sunset (helmsman's bell-times)
Configurable top-right slot: SpO₂ / Temperature / Time-to-Recovery / Floors / Distance
Pulsing sonar dots animation (optional)
Bluetooth + battery + notification icons
Move bar segmented like an ammunition magazine
Long-press zoom previews

Touch and hold the Stress or Body Battery panel to surface an 8-hour zoom chart with per-hour values and hour labels - like pulling a strip-chart from the trace recorder. Tap anywhere to dismiss.

Customization:

Top-right metric (5 options)
Sonar/radar pulse on/off
Active vs total calories
Bold font mode
Always-On Display

Full low-power AOD keeps the conn lit: same layout in dimmed palette so time, date, and key metrics stay readable on glance-down.
