Can a phone app stop sunburns before they start?
NCT ID NCT07830394
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers at the University of Utah are testing a mobile health app designed to help young adults protect their skin from the sun. The study enrolls 20 people aged 18 and older who have had at least one sunburn in the past year or who rarely use sun protection. For four weeks, participants receive text message reminders, read short education modules, make an action plan, and check UV weather information through the app. The goal is to see whether the app helps them use sunscreen and other sun protection more often and avoid sunburns.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A mobile health app with text message reminders, sun protection education modules, and action planning
- What this could lead to
- If the app helps, it could offer a low-cost way to reach young adults with sun safety reminders and lower their skin cancer risk over time.
- What could go wrong
- This is a small, four-week study with 20 people, so any changes in sun protection habits may not last or apply to larger groups. The app is a prototype, and results may not show a clear benefit.
