The Viiiiva is so much more than a heart rate monitor. The Viiiiva can act as an ANT+ to Bluetooth bridge so you can broadcast your ANT+ devices to your Bluetooth devices all through your Viiiiva heart rate monitor. The Viiiiva also records every second of your workout, including data from paired ANT+ devices. If something happens to your head unit or watch the Viiiiva will keep your data safe, up to 65 hours of it.

As a Good as they come!

The 4iiii Viiiiva is a game-changer in heart rate monitoring! Not just your standard HR monitor, the Viiiiva doubles as an ANT+ to Bluetooth bridge, allowing seamless connectivity between your ANT+ devices and Bluetooth gadgets. There are beginnings to see the devices without ANT+ pairing crop up so how 'future proof' is this HRM, time will tell.

Viiiiva Heart Rate Monitor works great with Rouvy

When using Rouvy indoor cycling app with Apple TV, I was limited to 2 bluetooth connections.
1. Wahoo Kickr (1st Gen) smart trainer
2. heart rate monitor.
I was unable to get Cadence input.
But with Viiiiva heart rate monitor I can use Wahoo Cadence Sensor Ant+ feed to the Viiiiva Heart rate monitor and then bluetooth both together to Rouvy App on Apple TV.

I’ve been trying to find a reliable heart rate monitor that runs off of CR2032 batteries for a while, I like that the battery lasts for so long. Took it out on my first ride today and it worked flawlessly, no dropouts whatsoever, 1hr30 each way with a coffee stop, I would have walked out of range and it reconnected perfectly, no issue with dried up sweat. Great value, highly recommended!
