Frequently Asked Questions

The Cordyn S5 Fitness Tracker Watch

How long does the battery last?

The Cordyn S5 is built to keep pace with your week. Under typical use (heart rate monitoring on, notifications active), you can expect several days of battery life. Turning off continuous heart rate tracking will extend this further.

Is the watch waterproof?

Yes. The S5 is IP68 rated — it can handle sweat, rain, and shallow water submersion. You can wear it through any workout. We don’t recommend deep-water diving or high-pressure water exposure.

What phones is it compatible with?

The Cordyn S5 is compatible with both iOS (iPhone) and Android devices. Sync via Bluetooth using the companion app.

Does it track heart rate continuously?

Yes. The S5 monitors your heart rate 24/7, giving you real-time data during workouts and resting heart rate data throughout the day and night.

Does it track sleep?

Yes. Wear it to bed and it will automatically track your sleep stages, duration, and quality — so you can optimise your recovery, not just your training.
