Over the past four years, we've delivered more than 20 feature-packed updates, each one designed to make your COROS device more powerful than the moment you first unboxed it. With App 4.0, we're bringing crisper in-app visuals, smoother navigation, and a more streamlined interface—plus new features like real-time voice alerts, on-watch strength guidance, and official workouts and training plans directly in the app.




1. A sharper look and a smoother flow.

The COROS app now features deeper colors, crisper icons, and a more refined design—making it easier to read, faster to navigate, and overall better on the eyes.

The COROS App has four main pages:

  • Progress: Where you can see everything you need to know about today, including workouts, sleep, Overnight HRV, steps, calories, and more.
  • Activities: View all of your recent activities and use the statistics button in the upper-right hand corner to see how your training has been over time.
  • Explore: Create new routes, view saved routes, and send them straight to your device.
  • Profile: Manage your device and app settings, set-up 3rd party integrations, edit your profile, and more.

On your Profile, customizing your watch is now more intuitive than ever. Check and manage your device storage for maps, audio files, routes, and workouts, or quickly access new watch faces to match your style.




2. Stay focused on what's ahead.

Get real-time audio updates on your pace, distance, nutrition alerts, and upcoming turns. With headphones connected to your watch* or phone, you'll be able to hear activity alerts to keep your eyes on the road, or technical trail, without having to look down at your wrist or bike computer. And if you don't have any headphones connected, your alerts can be played directly from your phone speakers as long as the COROS app is running in the background.

*Voice Alerts available in English, French, Chinese, and Japanese at launch, with more languages to be supported in the future.

3. Official training plans and workouts in the COROS app.

Browse and download over 200+ plans and workouts in the COROS app, created by experts and pros. Whether you're chasing a race goal or just need one perfect session, you can add it straight from your Profile page in a seamless download process, and get to work.

4. Make every rep count.

View guided animations during strength training sessions to help you perfect your form, and if your watch miscounts a rep or two (even the best devices can make mistakes), you can now edit your reps and weight directly from your watch. Additionally, strength exercises can now highlight both the primary and supporting muscle groups, so you know exactly which muscles you're training.



5. DURA navigation

Turn-by-turn alerts on DURA will now show you the name of the street to turn on, giving you more confidence in how you navigate. We've also added topographic maps to DURA, so you know how steep that mid-ride climb is to better gauge your effort.

Re-routing, on your terms.

DURA now gives you three options for re-routing, because we all want to intentionally get lost from time to time.

  • Auto Re-Route: View a re-route automatically to get back on course.
  • Manual Re-Route: Choose whether you want to go back to your original route, or continue off the beaten path.
  • No Re-Route: Stay in full control with no re-routing prompts at all. Get alerted that you're off route, but continue on your way without suggested route changes.

6. Chat with Cara, our virtual support assistant.

Have a question with device setup or need help figuring out a new feature? Cara, our new AI-powered support assistant, is built directly into the COROS app to give you fast, friendly help with troubleshooting, questions about product features, and more. Whether it's pairing a new device or finding the right setting, Cara's available 24/7 so you're never stuck waiting for answers.
