and your back view in real time
Even when working out alone at home, you can check your back, shoulders, hip line, and movement balance right away.

FAQ
Frequently asked questions
Do both devices need to be on the same Wi‑Fi?
For a stable real-time connection, using the same Wi‑Fi environment is recommended.
Do I need to create an account?

Where can I get another smartphone?
