Love but needs customization features
Response from developer
Hi there thanks for the feedback! We’ve made some changes that hopefully address your feedback.

Track your red light therapy sessions and understand your dosage in J/cm2. This app works with any brand of red light device, offering a clean timer, progress tracking, and consistency building without hardware lock-in.
1.3.0
October 1, 2026
Radia 1.3 comes straight from your feedback. • Log a past session. Forgot to start the timer? Tap Log a past session on Today, or + in History, and enter when it was and how long. It counts toward your streak and dose, and goes to Apple Health at the time it happened. • Your own body areas. Add areas like Left knee or Scalp. Each one gets its own History filter, stats and dose total. • A clearer device picker. You always see which saved device a session uses, so a dose is never quietly missing. • History now shows the device on every session. • A cleaner Live Activity: a tighter Dynamic Island, and your target counts down as a bar on the Lock Screen. • Smoother scrolling in History, and a fix for a rare freeze. Thanks for the reviews and emails. They shape every update.
