Getting Started with SuuntoPlus Development

Welcome to SuuntoPlus development

This guide walks you through the minimum steps required to build, test,
and submit a SuuntoPlus sports app.

If you follow the steps below, you can go from zero to a running app on
a watch or simulator in under an hour.

---

1. What is a SuuntoPlus Sports App?

SuuntoPlus sports apps extend Suunto watches with sport-specific logic,
calculations, and on-watch UI.

Apps are developed using:

• JavaScript (logic)
• HTML/CSS (UI)
• JSON (manifest & settings)

They are built and tested using SuuntoPlus Editor inside Visual
Studio Code.

2. Install the Required Tools

Visual Studio Code

SuuntoPlus apps are developed in VS Code.

Download (free):
https://code.visualstudio.com/

---

SuuntoPlus Editor (VS Code Extension)

SuuntoPlus Editor provides:

• App creation
• Simulator
• Build & validation
• Deployment to watch
• Packaging for submission

Download the extension (VSIX):
https://marketplace.visualstudio.com/items?itemName=Suunto.suuntoplus-editor

Install in VS Code:

1. Open Extensions view
2. Click … (top right)
3. Select Install from VSIX
4. Choose the downloaded file

After installation, you will see SuuntoPlus views and commands in VS
Code.

3. Create or Open a SuuntoPlus App

You can either:

• Create a new app
  → Command Palette → SuuntoPlus: Create New SuuntoPlus App

• Open an existing example app folder

Each app includes:

• manifest.json
• main.js
• UI templates (HTML/CSS/images)
• Optional data.json for settings

---

4. Test Your App Using the Simulator

The SuuntoPlus Simulator lets you test without a physical watch.

Open it via:

Command Palette → SuuntoPlus: Open SuuntoPlus Simulator

Simulator features:

• Multiple watch display sizes
• Adjustable speed (1x–50x)
• Simulated sensor data (HR, GPS, power, altitude, etc.)
• Support for FIT or Suunto JSON workout files
• Live inspection of input/output values

Use the simulator early and often — it catches most issues before
real-device testing.

---

5. Test on a Real Watch (Optional but Recommended)

You can deploy your app directly to a connected Suunto watch:

• Bluetooth (supported on macOS and Windows 10+)

Command:

SuuntoPlus: Deploy to Watch

Tip:
Disable Suunto mobile app syncing while developing, as it will test apps
from the watch.

---

6. Build and Package Your App

When ready:

• Build Sports App → creates .fea or .dev
• Create Source Package → required for submission

The build process:

• Validates your app
• Minifies JavaScript
• Converts UI assets
• Packages everything for watch compatibility

Fix all warnings before submission.

---

7. Submit Your App to Suunto

SuuntoPlus apps are submitted via Suunto API Zone.

General flow:

1. Join the Suunto Partner Program
2. Upload your source package
3. App is reviewed by Suunto
4. Approved apps are published to the SuuntoPlus Store

Links and detailed submission guidance are available in the official
documentation.

8. Where to Go Next

• Examples
  Explore real apps and reusable patterns

• Ask Other Developers
  Get help, discuss APIs, and solve problems together

• New to Test
  Share your app and get early feedback before submission
