Study Summary

This trial is testing a smartphone app to help patients with hypertension manage their sodium intake and improve their blood pressure. The app includes a just in time adaptive intervention (JITAI) to help patients make changes to their sodium intake.

Who is the study for?
This trial is for English-speaking adults with stable high blood pressure, who've been on the same hypertension meds for at least three months. They must own a smartphone compatible with the LowSalt4Life app and be willing to receive notifications. People with unstable blood pressure, secondary causes of hypertension, heart failure, certain kidney issues or those pregnant can't participate.Check my eligibility
What is being tested?
The study tests if a mobile app called LowSalt4Life can help manage sodium intake and lower blood pressure in hypertensive patients. It will compare the effectiveness of the app alone versus the app combined with JITAI (just-in-time adaptive intervention).See study design
What are the potential side effects?
Since this trial involves using a mobile application rather than medication, traditional side effects are not expected. However, participants may experience stress or frustration from lifestyle changes or technology use.
