Heart Rate Graph for Better Data Visualization
Dear Hammerhead Team,
I’ve been using the Karoo 3 and really appreciate its innovative design and data presentation. The current heart rate display, with five zone dots and a live heart rate circle, is a unique way to show effort levels. However, I believe adding a more traditional heart rate graph (like the one in the attached image) would be a fantastic improvement.

A progressive graph with color-coded zones would allow users to see heart rate trends more clearly, making it easier to track intensity changes over time. This feature would be especially useful for structured training and pacing during long rides.
I think this addition would greatly enhance the Karoo 3’s real-time data feedback. Thank you for considering this suggestion—I’d love to see it in future updates!
Best regards,
