The 80/10/10 Diet app brings Dr. Douglas Graham's fruit-first method to your phone. Get a daily note in his voice, a simple raw meal plan and a coach you can ask anytime. Dr. Graham wrote The 80/10/10 Diet and has taught raw, low-fat living for decades. This app turns his method into small daily steps you can follow. Each day opens with a short note from Dr. Graham and one clear focus. Your plan lays out fruit-first meals and gentle movement, and you check them off as you go. Swap a meal when you need to and keep going. Have a question about food combining, cravings or eating out? Ask your coach by text or start a hands-free voice call. The coach is AI, built on Dr. Graham's method and teaching. It answers in plain words and keeps to the 80/10/10 principles: whole raw fruits and greens, fat at or under 10 percent, no salt and no processed food. When you start, you answer a few questions about how you eat now. The app builds a raw plan around your answers and shows where you stand on energy, cravings and digestion. Browse simple fruit meals that need no cooking, save your favorites and learn the method through short lessons. Join the weekly live community meetup hosted by Dr. Graham and connect with people who eat the same way. The 80/10/10 Diet is for anyone curious about raw, plant-based eating, from a first fruit breakfast to a fully raw lifestyle. It offers education and guidance, not medical advice. Talk to your doctor before you make big changes to your diet. Some features need a subscription, billed monthly or yearly through your Apple ID. It renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
