Magic Motion App
Magic Motion App
Use Magic Motion App for vibration control and simple Kegel exercise support. After the user with Crystal Duo connects it to their phone in the app, a partner in another city can remotely control it. Both users need the Magic Motion App and a stable internet connection. Crystal Duo does not use Magic Kegel App or pressure-sensor feedback.

Crystal Duo: vibration + weight
A vibrating trainer and a weighted ball in one set. Choose Crystal Duo when you want a playful, app-optional experience rather than a sensor-feedback trainer.
Use it your way
Use manual controls for vibration, or open Magic Motion App for app control and simple Kegel exercise support.
Not a sensor-feedback trainer
For pressure or multi-point feedback that helps you recognize a contraction, compare Kegel Coach, FitCute Rejuve, and Kegel Master Gen2.
How to choose and use Crystal Duo
Crystal Duo is not a sensor-feedback Kegel trainer. Use the vibrator manually or through Magic Motion App, and use the weighted ball when you want a more traditional resistance-style Kegel experience. For feedback-led guidance, compare the dedicated sensor trainers in the Kegel guide.
Care and comfort
- Read the user guide before your first session.
- Start with a comfortable vibration setting and stop if you feel pain or discomfort.
- Clean with warm water and mild soap or toy cleaner, then dry thoroughly before storing.
- Use Magic Motion App for optional app control; manual controls work without the app.
