Description

Description

The Viiiiva heart rate monitor from 4iiii is comfortable and easy to wear and provides very precise measurements. As you can bundle multiple ANT+ sensors and Bluetooth signals into a single Bluetooth signal, this heart rate monitor is ideal if, for example, you use Apple TV in combination with Zwift. The Viiiiva heart rate monitor then acts as an ANT+ bridge, enabling you to connect all your sensors with your Apple TV or other Apple device.

The 4iiii Viiiiva features the so-called Beat-To-Beat system, a renewed and optimised heart rate measuring system that makes the Viiiiva up to 10 times more sensitive in registering your heartbeat than other heart rate monitors. As such, it ensures a very accurate heart rate recording, which is ideal for cyclists who make high demands on their cycling gear. In addition, the Viiiiva is very user-friendly and has a great memory; it can store up to 65 hours of training data.

Furthermore, with the Viiiiva you have access to useful 4iiii training tools such as 4iiii PRECISION and Sportiiii Coaching. You can use these tools to keep track of your training data in an organised manner, and optimise your workout programme. Do you also go to the gym to exercise? Know that the Viiiiva can also be paired easily with cardio devices, which is ideal for a heart rate workout in the gym. The included coin cell battery will give you up to 200 hours to enjoy all the comforts of your Viiiiva heart rate monitor.
Do you want to connect all your ANT+ sensors to a Bluetooth device like an iPhone? And conveniently have all your data centralised during a Zwift session? Then choose the 4iiii Viiiiva heart rate monitor!

Technology

ANT+ to Bluetooth Bridge
This heart rate monitor enables you to easily collect data from other ANT+ cycle sensors, such as a bike computer, speed and cadence sensors. You can then forward these data to your iOS or Android smartphone or tablet via Bluetooth. This way, you have all your data in one place, which makes the Viiiiva perfect to use in combination with your turbo trainer. You will not need an ANT+ Dongle anymore.

Nice belt but poor data quality (dropouts and spikes)

- Anna 14 February 2024

Unfortunately there were data errors in 5 out of the first 6 workouts I tried (either HR dropouts or HR spikes), despite following the instructions carefully, and once it had failed the first time, I tried: super-wetting the band, using electrode glue, rotating the box partway to the side, changing tshirt, changing sportsbra, and any other tricks I've learned that may apparently help to eliminate such things. Sadly I won't be using this product again.

Pros & Cons

Front clipping belt
Low profile box
Narrow band
Dropouts in the HR data
Spikes in the HR data

4 / 5

Does what it should but is difficult to work with the app, etc.

- Oskar 4 December 2023

After much trial and error, I got it to work as an ant+bridge for the phone.
