HAYLOU FUN 4.0: A Fresh Look and Smarter Everyday Features
Your smartwatch is only part of the experience. With HAYLOU FUN, your activity records, personal goals and device settings come together in one place.
The HAYLOU FUN 4.0 update brings a redesigned interface, dark mode and new ways to track your progress. Here's what’s new and which features are available on supported HAYLOU smartwatches.
1. A Redesigned Interface with Dark Mode
HAYLOU FUN 4.0 introduces a refreshed UI designed to make everyday navigation more intuitive.
Dark mode is also here, offering a darker interface for checking your activity and settings in low-light environments—whether you're winding down at night or reviewing a workout after an evening run.
2. Workout Calendar and Route Videos
Building a routine starts with consistency. The Workout Calendar shows whether you’ve exercised today, giving you a quick overview of your daily activity.
Workout route videos add a visual dimension to your activity records, making it easier to revisit the routes behind your runs, rides and outdoor sessions. Available route information depends on the recorded activity and supported device features.
3. Weight Tracking and Goal Setting
HAYLOU FUN now lets you record your weight and set a personal target.
Use these records to follow longer-term trends and keep track of your progress over time. Daily measurements can fluctuate, so it's more useful to focus on consistent records than a single number.
Weight tracking is intended for general wellness and personal record-keeping, not medical diagnosis.
4. HRV and Vitality Index on HAYLOU Watch Hyper
With supported devices, HAYLOU FUN adds HRV (heart rate variability) and vitality index data for a broader view of your personal wellness information.
HRV measures variations in the time between heartbeats. It can provide useful context for understanding changes in your body, but a single reading is not a definitive measure of health or recovery.
Compatibility: HRV and vitality index features are supported on HAYLOU Watch Hyper (HSS02). Availability varies by device.
5. WhatsApp Quick Replies on Supported Watches
Stay connected without reaching for your phone every time a message arrives.
WhatsApp quick replies are available on selected HAYLOU smartwatches:
Feature availability may depend on your phone, notification permissions, software and device compatibility.
6. What's Coming Next to HAYLOU FUN?
More improvements are planned for future updates, including:
● Workout sharing: New ways to share activity records.
● Manual weather location selection: Choose a weather location manually.
● Editable women's health records: More flexibility when managing personal records.
These features are planned, not currently available. Release timing and final functionality may change, so check the app for updates.
