Your meal, in one sentence. Describe what you’ve had. No searching, no barcodes. Grail works out the rest. Logging a meal should take five seconds, not five minutes of searching a database. With Grail, you just say it: “Two eggs, sourdough toast, and a coffee with oat milk.” That’s it. Grail’s AI turns your words into an itemized meal: every food, portion, calories, protein, carbs, fat, fiber, and micronutrients, ready to confirm and save. Prefer typing or a photo of your plate? Both work too. NO WALL IN FRONT OF THE MIC Open the app and log. No account required, no card, no quiz. Sign in later with Apple if you want your log synced. Your meals carry over. PRIVATE BY ARCHITECTURE, NOT BY PROMISE Your meals live in your own private iCloud database. We run no user database, so we cannot read, sell, or lose your food diary. There is nothing to breach. No analytics, no ads, no tracking SDKs. AI analysis requests carry no name, no account, no IP address, and photos are stripped of location data before they leave your phone. Live transcription happens on your phone, not on the internet. A LOGGER, NOT A COACH Grail shows you what you actually ate: clear daily totals, weekly trends, eating patterns, and micronutrient coverage drawn from your own logs. Insights describe your data; they don’t lecture you about it. No streaks guilt, no confetti, no diet ideology. WHAT YOU GET • Voice-first logging, with your words on screen as you speak • Text and photo logging when that’s easier, like messaging a friend • Itemized nutrition: calories, macros, fiber, sugar, water, micronutrients • A calm dashboard: rings, macro trends, eating-pattern heatmap, hydration • Apple Health sync, writing your nutrition straight into Health (we do not see your Apple Health data) • Meal editing with portions that rescale nutrition accurately • Sync across your devices through your own iCloud FREE TO USE, HONESTLY Log free on up to 3 days every month, with full features. Enough to feel the magic, forever. Grail Premium unlocks unlimited logging: $6.99/month or $49.99/year with a 7-day free trial. Your history is never held hostage. Everything you’ve logged stays viewable even without Premium. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage in Settings. Grail is not a medical device and does not provide medical advice. Nutrition figures are AI estimates. Talk to a professional for anything that affects your health.
