Born from Exploration

Suunto has always been about pushing boundaries—whether in the mountains, the ocean, or deep within one’s own performance. As athletes and adventurers began using Suunto watches for more than navigation and tracking, a new idea emerged: what if users could expand their watch’s capabilities on demand? From that idea came SuuntoPlus™, a digital playground of experiences designed to make every Suunto watch as personal, powerful, and adaptable as its user.

A Platform for Continuous Innovation

SuuntoPlus is a living ecosystem. It’s a collection of apps, connected devices, watfaces, and guidance content that evolve with technology and user needs.
Each SuuntoPlus brings something new to the wrist:

Performance insights like hill reps, loops, and race pacing.
Environmental awareness like weather insights or safe sunrise/sunset guidance.
Adventure companions like bearing navigation or climb metrics.
Wellness and safety tools that help users understand how their body responds to effort and recovery.

Instead of waiting for major firmware releases, SuuntoPlus allows users to continuously discover new tools and sports experiences, keeping their devices fresh and inspiring.

SuuntoPlus Sports App

SuuntoPlus Sports Apps are lightweight, customizable features that run on Suunto watches during an activity. They offer sport-specific enhancements such as timers, data overlays, calculations, or guidance, and can be selected from the SuuntoPlus Store. These apps help athletes and coaches get more out of their workouts by visualizing and reacting to sensor data in real time.

As Suunto continues to innovate, SuuntoPlus remains the bridge between timeless hardware and evolving software. It ensures that every Suunto watch can grow with the user—offering new insights, experiences, and adventures with every update.

Development flow with SuuntoPlus Sports Apps

To start building SuuntoPlus Sports Apps, developers need to join the Suunto Partner Program. Once accepted, they gain access to developer tools and documentation. While the API Zone submission process is still evolving, developers can already build and test their apps locally using Suunto’s tooling. SuuntoPlus apps are structured projects with defined inputs, outputs, and logic, packaged for deployment on Suunto devices.

SuuntoPlus Editor

The SuuntoPlus Editor is a Visual Studio Code extension available for Windows and macOS. After installing VS Code, developers can download the .vsix installer file for the SuuntoPlus Editor and enable it. Connecting a Suunto watch via USB or Bluetooth allows developers to test and deploy apps directly to the device. A new app can be created in seconds using built-in commands.

Key Features of SuuntoPlus Editor

The editor provides a full development environment with commands to create, preview, simulate, and deploy sports apps. It includes a file explorer view for apps, a simulator for testing with adjustable input data, and real-time preview tools for HTML templates. The packaging tool ensures that apps are minified, validated, and ready for watch installation.

Building with the SuuntoPlus Editor

Each SuuntoPlus app includes a manifest file that defines its metadata, a JavaScript file for logic, and HTML templates for the watch display. Apps rely on system callbacks like evaluate() and onLoad() to process live data. The simulator enables testing different values like heart rate or power in real time. Developers can reference real examples, such as interval counters or climbing trackers, to build their own logic and interfaces.

Reference Documentation & Examples

The documentation provides a list of watch data resources that developers can use in their apps, from heart rate and GPS to swim strokes and environmental data. Sample projects demonstrate how to structure code, use templates, and simulate workouts. This section helps developers understand the building blocks of SuuntoPlus apps and how to turn real-time data into meaningful insights on the watch screen.

Publishing Your SuuntoPlus Sports App

Once development is complete, you can publish your SuuntoPlus Sports App through your profile on Suunto's Apizone platform. This process requires you to upload the final app package, a well-written description, and images that represent the app accurately. It's essential to provide complete and truthful information—any missing details, misleading content, or unauthorized images will prevent publication. By submitting your app, you also grant Suunto the rights to distribute it to other users through the SuuntoPlus Store

Receiving Feedback and Updating Your App

Once Suunto reviews and approves your SuuntoPlus Sports App, it will be published in the SuuntoPlus Store for users to download and use on their watches. After publication, Suunto users can send feedback through the store, which will be delivered to your Apizone account email via Suunto’s backend system. If feedback highlights issues or the need for improvements, it’s your responsibility to make necessary updates or clarify the app content to ensure a better user experience.
