Summary

This study tests a mobile app called Navio that helps people with chronic pain track their pain levels, mood, and medication use twice daily. Researchers want to see if the app can reveal patterns that improve pain management. The study involves about 100 adults with chronic pain lasting more than three months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Navio Mobile App
What this could lead to
If successful, this app could help people with chronic pain and their doctors better understand pain patterns and improve treatment decisions.
What could go wrong
This is a small pilot study focused on tracking, not treatment. The app may not be easy to use or may not provide clear benefits over standard care.
