Aolon Tetra R4 Smart Watch (Black, 1.43 Inch)

How accurate is the heart rate monitoring on this smartwatch?

The Aolon Smart Watch uses professional algorithms to monitor heart rate continuously throughout the day. The optical sensors on the back of the watch detect blood flow changes to calculate your heart rate. Whilst not medical-grade equipment, user reviews indicate reliable readings for fitness tracking purposes. The watch also monitors blood oxygen levels and provides sleep analysis based on heart rate variability patterns.

Can I swim with this watch and what does IP68 waterproof rating mean?

Yes, the IP68 waterproof rating means the watch can withstand continuous submersion in water up to 1.5 metres deep. You can swim, shower and exercise in the rain without damaging the device. The rating also provides complete dust protection. However, avoid hot water exposure like saunas or hot showers, as extreme temperatures can affect the seals and internal components.

How long does the battery actually last with normal use?

The 350mAh battery typically provides 7-9 days of use with standard settings including heart rate monitoring, notifications and occasional GPS use. Heavy users with always-on display, frequent GPS tracking and multiple daily workouts may see 3-5 days. The AMOLED display's low power consumption helps extend battery life compared to traditional LCD screens. Charging takes approximately 2 hours from empty to full.

Which phones are compatible with this smartwatch?

The watch connects via Bluetooth to Android devices running version 4.4 or higher and iPhones with iOS 9.0 or later. This covers virtually all smartphones from the last 8 years. You'll need to download the companion app to sync data, receive notifications and customise settings. The app is available free from Google Play Store and Apple App Store.

What sports and activities can this watch track automatically?

The watch includes over 100 sport modes covering running, walking, cycling, swimming, yoga, football, basketball and many specialist activities. Built-in GPS with AGPS support tracks outdoor routes and distance accurately. Motion pattern recognition can automatically detect when you start exercising and begin tracking without manual activation. Each mode records specific metrics relevant to that activity type.

How bright is the LED flashlight and how useful is it?

The integrated LED flashlight provides sufficient illumination for close-up tasks like reading in dark conditions or finding items in bags. Whilst not as powerful as a phone torch, it's incredibly convenient for quick lighting needs without reaching for your phone. Users report it's particularly useful for nighttime navigation, checking locks or reading menus in dim restaurants.

Can I customise the watch faces and what options are available?

The watch includes multiple pre-installed watch faces ranging from digital to analogue styles, though some users find the selection limited. There's a custom watch face feature, but it offers basic customisation compared to premium smartwatches. You can change colours and some complications, but advanced personalisation is restricted. The 1.43 inch round display shows watch faces clearly with good colour reproduction.

What's included in the box and are there any additional costs?

The package includes the Aolon Smart Watch, silicone watch band, magnetic charging cable and user manual. No additional purchases are required to start using the device. The companion app is free to download and use. The watch band is standard 22mm width, so you can replace it with third-party straps if desired. No subscription fees apply for health tracking or app features.
