MD3MAX FAQs

Can the MD3MAX make and receive phone calls?

No. The MD3MAX shows incoming call alerts on your wrist, but the call itself is answered on your phone. If you want to talk through your watch, browse our Bluetooth calling smartwatches.

Is the MD3MAX waterproof?

It is rated IP68 for dust and water resistance, so rain, sweat and hand washing are fine. Avoid hot showers, saunas, sea water and diving, as heat and pressure can damage the seals.

How long does the battery last?

It has a 380 mAh battery. Real-world battery life depends on screen brightness, notifications, calling and how often health tracking runs. See our smartwatch battery life guide for tips.

Does the MD3MAX work with iPhone and Android?

Yes, it is compatible with Android 5.0+ / iOS 9.0+ phones via the companion app.

Are the health readings medically accurate?

No smartwatch in this range is a medical device. Heart rate, blood oxygen, blood pressure, temperature and similar readings are estimates to help you spot trends in your general fitness and wellbeing. They are not suitable for diagnosing or managing a medical condition, so always speak to a healthcare professional about health concerns.
