NordicTrack S20i owners have a confirmed QZ setup for using Runna on a second phone. In public GitHub issue #4607, the owner tested a new QZ build and reported that Runna could start the treadmill from 0 and that all controls worked as expected.
The confirmation was made with a test build, so use a QZ release or test build that contains the relevant fix rather than assuming every older store build has identical behavior.

Compatibility summary
| Equipment | NordicTrack S20i treadmill |
| QZ connection | QZ connects to the treadmill and provides the treadmill bridge |
| Runna workflow | Runna on a second iPhone can connect through QZ’s virtual treadmill path |
| Speed control | Starting the treadmill from 0 and normal speed control were reported working in the confirmed build |
| Incline/control | Incline and the other treadmill controls were reported working in the same test |
| Evidence boundary | One public user confirmation and a closed issue; firmware, QZ build and phone behavior can still affect results |
Setup notes
- Use a QZ build that includes the fix validated in issue #4607.
- On phone 1, open QZ and connect it to the NordicTrack S20i.
- On phone 2, open Runna, choose the treadmill-recording workflow, select the QZ treadmill, and start the workout.
- Test speed and incline at a low setting before beginning a full workout.
When the S20i has a built-in iFIT tablet
Do not treat a built-in tablet as a simple phone-only Bluetooth setup. The old QZ Companion procedure for NordicTrack tablets is obsolete. Depending on the tablet interface, use the current iFIT Pro/FitPro QZ release artifact installed on the treadmill tablet, or the gRPC artifact intended for newer 3D iFIT interfaces. If the treadmill tablet is not part of the QZ path, keep it fully out of the Bluetooth connection and use the separate QZ phone/device path.
QZ integrations
QZ can bridge supported equipment to apps such as Zwift, Runna, MyWhoosh and ROUVY, while platform and device capabilities determine the exact metrics and controls available. QZ also includes Apple Health/HealthKit, Garmin Connect, Strava and Google Health/Health Connect workflows where supported by the platform and settings.
