OncoDiary helps people living with cancer and those caring for them stay connected, organized, and supported through treatment, recovery, remission, survivorship, and caregiving. A cancer diagnosis changes everyday life. There are symptoms to remember, medications to take, meals to plan, appointments to prepare for, and questions you don't want to forget. OncoDiary brings everything together in one calm place, helping you feel more prepared and a little less alone. YOU DON'T HAVE TO DO THIS ALONE Cancer care is rarely a journey taken alone. Invite a trusted family member or caregiver into your private Care Plan and choose exactly what to share. Share reminders, symptom updates, grocery lists, appointments, support requests, and messages while keeping personal reflections private. When someone asks, "How can I help?", OncoDiary helps make the answer simple. TRACK YOUR HEALTH Every day is different. Record symptoms, pain, energy, mood, sleep, temperature, food, hydration, movement, reflections, and personal notes. Track weight and body changes, including hair loss, swelling, skin and nail changes, scars, and anything else that's important to you. Over time, your history helps you notice patterns, prepare for appointments, and better understand how treatment is affecting your body. Your Care Rhythm Score offers a gentle reflection of your daily care habits and wellbeing. It is designed for personal support—not medical use. NOURISH YOUR BODY Treatment can change the way you eat, feel, and recover. Log meals, calories, protein, carbohydrates, fats, hydration, and weight. Save favorite meals, set protein goals, and follow your nutrition over time with simple history and progress. Create grocery lists for food and household essentials, then share them with caregivers so loved ones know exactly how they can help. STAY ORGANIZED Create reminders for medications, appointments, hydration, nutrition, rest, and treatment preparation. Save symptoms, medication concerns, treatment experiences, and questions as they happen so you feel more prepared when meeting with your healthcare team. SUPPORT WHEN YOU NEED IT Sometimes support means practical help. Sometimes it means taking a quiet moment for yourself. Explore a growing collection of Journals with thoughtful articles, practical guidance, and emotional support. You'll also find breathing exercises, relaxation tools, soothing sounds, reflection activities, educational content, food and symptom guidance, and daily encouragement. Included with OncoDiary is *Through the Storm* by Dr. Ellie Urban, an oncology psychologist with more than 15 years of experience supporting people affected by cancer. Written for patients, caregivers, and families, it offers compassionate guidance, reassurance, and hope throughout the cancer journey. "A must-read for cancer patients, caregivers, and close friends." - Gayle M. "Compassionate and filled with understanding." - Richard R. Where available and with your permission, OncoDiary can connect with Apple Health to include step activity as part of your daily care journey. YOUR PRIVACY You control what is shared. Private reflections remain private, and caregivers only see the information you choose to share. IMPORTANT NOTICE OncoDiary supports organization, communication, nutrition tracking, reflection, and wellbeing. It does not provide medical advice, diagnosis, treatment, emergency monitoring, or clinical decision support. The Care Rhythm Score is for personal reflection only and is not intended to diagnose, monitor, predict, or treat any medical condition. Always follow the guidance of your doctor or healthcare provider. If symptoms are urgent or severe, seek immediate medical attention.
