Red light therapy is booming, but practitioners are left to track sessions and results in a notes app. RedLightCoach gives them a proper companion: a guided session timer, a PASI calculator to measure skin improvement, trigger analytics, a full treatment log, and a Gemini Vision AI skin scan that grades progress photos.

Free tracking

  • Session timer — guided red light sessions with the right exposure tracking.
  • Trigger tracker — checklist with frequency analytics.
  • Treatment log — creams, biologics and light therapy in one place.
  • PASI calculator — reproducible skin-severity scoring.

Pro: AI skin scan and coach

Pro ($9.99/mo or $49.99/yr) adds an AI photo coach — snap a progress photo and Gemini Vision grades it — plus an AI coach chat grounded in your flare and session history. It turns "I think it's working" into a tracked trend.

Wellness aid: RedLightCoach is educational only, not a medical device. The PASI calculator and AI grading produce general information, not a diagnosis. See the RedLightCoach listing.

Why a dedicated app beats a timer

Red light therapy's value is in consistency and dose tracking over weeks. A generic timer can't show you whether your skin is actually improving. Pairing the timer with photo grading and PASI is what makes RedLightCoach sticky. Browse more health & wellness apps or submit your own.
