There are some Sufferlandrians out there that like to use multiple applications at once. Some of the more popular Apps are Trainer Road and Zwift. You can run the Sufferfest App in combination with other training Apps but to do it....
EVERY APP NEEDS ITS OWN ANT+ DONGLE
Each Application will need its own ANT + dongle. That means, if you want to run the Sufferfest App while capturing your data on a TrainerRoad free ride profile and hitting Zwift at the same time, you will need one ANT + connector for each App.
Now, some people have been successful using ANT + for one App and then connecting Bluetooth for the other App. It is possible to do this, but the Minions at Sufferlandrian Services have found unreliable connection issues with the BLTE connection.
