Radiant RT Symptom Support is a calm, evidence-informed radiation therapy symptom tracker for people going through RT — created by a PA-C specializing in radiation oncology and grounded in 90+ clinical trials. Radiation treatment is a marathon, not a sprint. Many people feel relatively well at first, then notice symptoms gradually build as treatment continues. Radiant RT Symptom Support is designed to meet you where you are each week — gently. WHAT YOU GET • DAILY CHECK‑IN — Five quick sliders for Energy, Skin, Pain, Mood, and Sleep. Track how you’re feeling in about 30 seconds a day. Based on your check-in, Radiant delivers one of 26 comprehensive symptom responses — each including evidence-informed guidance, audio recommendations, and safety information — triggered by symptom intensity, duration, or both, with combination responses when multiple symptoms overlap. • LEARN, WEEK BY WEEK — Short, honest guides about what may happen before treatment, during each phase of RT, and after treatment ends. Written in plain language. No scare stories, no sales pitch. • GUIDED AUDIO — 12 guided audio sessions to help with procedural anxiety, cumulative fatigue, sleep, and the emotional side of treatment. Designed specifically for the RT experience. • YOUR OWN TRENDS — Simple graphs of your five domains over time, so you can spot patterns, share them with your care team, and feel more prepared for appointments. • STAYS WITH YOU — Free content is available during the early part of treatment. Monthly Access and Annual Access unlock extended education, longer trend history, and the full guided audio library when support often matters most. WHY IT EXISTS Created by a PA-C specializing in radiation oncology, Radiant RT Symptom Support was built for the moments between appointments — when questions come up at home, symptoms change, and you may wonder what is expected. Radiation therapy can feel lonely. The waiting room is quiet, the science is complicated, and the day-to-day experience often happens outside the clinic. Radiant RT Symptom Support is not trying to replace your oncology team. It helps you pay attention to how you’re doing, understand what may be expected, and share clearer information with your clinicians. Radiant’s content is grounded in a review of 90+ clinical trials, with supporting research accepted for publication in Seminars in Radiation Oncology expected in summer 2026. WHAT IT ISN’T Radiant RT Symptom Support does not diagnose, treat, or replace clinical care. It is not a medical device and does not provide medical advice, clinical monitoring, or alerts of any kind. It has not been reviewed or cleared by the FDA or equivalent authority. For any medical question or emergency, always contact your radiation oncology team or local emergency services. SUBSCRIPTION Monthly Access and Annual Access unlock the full educational library, the full audio library, and longer trend history. • Billed to your Apple ID at confirmation of purchase • Automatically renews unless canceled at least 24 hours before the end of the current billing period • Manage or cancel any time under Settings → Apple ID → Subscriptions • Prices are shown in the app before purchase PRIVACY Your check‑in data is yours.
