ZmanIQ - Garmin App

Connect IQ app for Garmin wearables for convenient Zmanim lookup & reminders.

Development

2026 Update:

I wanted this to be an AI-free project, but I've succumbed to some minor Copilot-tempted changes just before the major PR with no way to undo.
Sigh... Welcome to the contributors list, Copilot, I guess.

Prerequisites

• Connect IQ SDK
• Java RE 8 (v1.8.0 or higher)
• VSCode Extensions:
  • Monkey C
  • Prettier Monkey C
• Generate a Garmin Developer Key: Garmin Docs - Generating a Developer Key

Running app in simulator

0. Connect your watch to your computer
1. Open the project in VSCode and open one of the .mc files
2. Run simulator: Ctrl+Shift+P -> Connect IQ: Run

Running app on device

Adapted from: Garmin Docs - Side Loading an App

The wizard below will create an executable (PRG) of the project for that watch.

0. Plug your device into your computer
1. Use Ctrl + Shift + P to open the command palette
2. In the command palette type "Build for Device" and select Monkey C: Build for Device
3. Select the product you wish to build for. I've got the Forerunner 245 Music. If you are unable to choose a device for which to build (the menu appears empty), it means that the device wasn't particularly supported, but it should still work if you add it.
4. Choose a directory for the output and click Select Folder
5. In your file manager, go to the directory selected above
6. Copy the generated PRG files to your device's GARMIN/APPS directory
