Hevy Workout Routine Companion & History Tracker for Pebble Smartwatches

NOTE

This is a Vibe-Coding project! 🎸✨ Built interactively using advanced agentic AI pair-programming to prototype, test, and implement features on-the-fly.

PebbleGym brings your fitness routines directly to your wrist. Compatible with all Pebble platforms (optimized for Pebble Time 2/emery), it allows you to import your training plans from the provider Hevy using public links. During the workout, the watch displays the current set with target values, compares them with your history ("Last Time"), and logs your achieved weights and repetitions. Thanks to a clever protection mechanism (long-press), accidental clicks are prevented, and a quick exercise menu lets you flexibly jump between exercises at any time if a machine in the gym is occupied.

TopoNav brings offline-style topographic maps and GPX path guidance to your Pebble smartwatch. It streams live OpenTopoMap tiles from your smartphone companion, rendering detailed contour lines, hiking trails, and rivers in Pebble-native 64 colors (GColor8).

Whether you are hiking, walking, or exploring new paths, TopoNav keeps you oriented without needing to pull out your phone.

Key Features:

🗺️ Topographic Map Tiles: Real-time rendering of elevation contours and walking trails.
🥾 On-Watch Route Manager: Swap, start, or deactivate GPX routes directly from a dedicated on-watch menu.
📍 Sensor-Fused Compass Chevron: Real-time direction arrow using the watch's magnetic compass when standing, and switching to GPS-course when walking to filter out wrist-swing jitter.
⏺️ Activity Recorder: Long-press the Select button on your watch to record your walk. View metrics and download the standard .gpx file from the settings webview.
📊 Dual-Column Stats Dashboard: Check average speed, distance (walked / remaining), elevation profile (gain / loss), and coordinates at a glance.
🔊 Vibration Alerts: Stay on track with haptic turn-by-turn prompts and warnings if you drift more than 50 meters off-route.
🔋 High Contrast UI: High-legibility status bars and an integrated watch battery percentage.
Requirements: Requires a persistent connection to your phone's Pebble app with GPS and Internet access enabled.
