Nyxava is a harm-reduction support tool, not a replacement for emergency medical care. If someone is unconscious, not breathing normally, turning blue/gray, having seizures, overheating severely, or cannot be woken up, call emergency services immediately.
More native app downloads are coming soon. For now, Nyxava's website and iPhone Home Screen version are the fastest way to access the latest tools.
