Use TrainerRoad & Zwift at the same time

Hi, I want to use TrainerRoad and Zwift at the same time, I use a Wattbike atom as my trainer, I have an iPhone 11 and an iPad, I have read about using Ant+, does anyone use this set up currently and what do they use?

Welcome! Probably worth having a dig through this thread: Using TR and Zwift Concurrently
