SmartRep: Modular Rep Counter for Bangle.js 1

This pull request adds the SmartRep application to the Bangle.js App Loader.

SmartRep is a modular, user-friendly fitness app that detects and counts repetitions for common gym exercises using Bangle.js 1's built-in accelerometer. Each exercise uses lightweight detection logic tailored to real movements.

✅ Features:

• 8 Supported Exercises:
  • Bench Press
  • Bicep Curls
  • Cable Rows
  • Lateral Raise
  • Pushup
  • Shoulder Press
  • Triceps Pushdown
  • Squats
• Touch-free interface with button-based navigation
• Target rep setting before session
• Circular animated rep indicator
• Visual and haptic feedback
• Custom app icon and full UI branding
• Modular detection logic files per exercise (logic/ folder)

🧠 Internals:

• Main UI: smartrep.app.js
• Exercise logic: logic/*.js
• Metadata: metadata.json
• Icon: smartrep-icon.png

The application has been tested on real Bangle.js 1 hardware. All code is safely sandboxed within its directory and follows the BangleApps structure.

Ready for review and merge. 🙌

Looks good - unfortunately I don't have a Bangle1 to test on, does anyone else?

Hey! This app looks like something I would use! Unfortunately, I don't have a Bangle.js 1. What makes this app incompatible with the JS 2? Perhaps we could design a workaround...

Hi - are you really sure this works? Because I can see quite a few issues - some are listed in the pre-merge tests: https://github.com/espruino/BangleApps/actions/runs/16104483721/job/45451159898?pr=3927

• Bangle.js doesn't support folders, so trying to put stuff in logic/* doesn't make that much sense (and no URL has been supplied for the files in the metadata anyway)
• the icon uploaded is a large png file, not the 48px JS format
• looking at the app.js I can't see where it loads any of the logic files like tricepspushdown.js mentioned in metadata (which doesn't match triceps_pushdown.js)

It looks like a great idea, but I'm not really sure I see how it's meant to work? as far as I can tell even when running right now it'll display the UI but doesn't really use any of the sport style JS files?
