Tools That Work Differently

No text. No chatbots. No accounts required. Just evidence-based physiological tools you can use in 3-5 minutes—during an anxiety spike, before a meeting, or as part of a daily practice.

Important

These tools are not therapy. They are based on research but have not been validated in clinical trials. They may help some people with stress reduction and relaxation—they are not treatments for mental health conditions. If you are experiencing mental health difficulties, please consult a healthcare professional.

Physiological approaches consistently outperform text-based digital interventions. That's the design rationale.
