Vehicle Motion Cues is a clever free feature, but it only helps while you're using your phone — it can't prevent motion sickness from looking out the window or sitting in a moving vehicle. Stillwave's 100 Hz pre-treatment works regardless of what you're doing afterward. They complement each other well.
They solve different problems. Vehicle Motion Cues helps reduce sickness while reading on your phone. Stillwave prevents motion sickness from the vehicle movement itself. You can use both.
Apple hasn't published peer-reviewed studies on its effectiveness. The concept of reducing visual-vestibular conflict is sound, but the specific implementation hasn't been clinically validated. Stillwave's 100 Hz approach was studied at Nagoya University.
Yes. Use Stillwave before your trip for vestibular protection, and enable Vehicle Motion Cues if you plan to use your phone during the ride.
60 seconds of sound, up to 2 hours of relief. No side effects.
