Signal combines your Oura Ring, Apple Health, and nutrition data into one personal dashboard — with AI coaching, a weekly nutrition report card, calorie add-back for workouts, accountability with friends, and every insight built from your actual numbers.
Connects with
Signal connects your wearable, workouts, and nutrition into a single view — then tells you what it all means.
Every Monday, get an A–F grade for each macro — calories, protein, carbs, fat, fiber, and sodium — compared to your personal goals. Includes a written narrative: what went well, what needs work, and one specific focus for next week.
Add friends and see each other's daily wins — sleep score, steps, calories, workouts, and streaks. Send emoji pings to celebrate or nudge. You control exactly what you share: calories, sleep, steps, workouts, readiness, weight, or macros.
See readiness, sleep score, HRV, steps, active calories, and nutrition totals every morning before you start your day. Tap any metric to get a plain-English explanation of what it means for you today.
Ask anything in plain English — "How does alcohol affect my sleep?" or "When do I hit my protein goal?" Signal answers with real numbers from your last 90 days, not generic advice. Special alcohol & sleep analysis compares your HRV and readiness score on drinking vs. non-drinking nights. Weekly executive summaries cover wins, risks, and what to do next.
Describe a meal, snap a photo of food or a nutrition label, or search the USDA database. Build and save recipes with full per-ingredient macro editing. Save frequently-eaten foods to your My Foods library for one-tap logging. Import years of history from MyFitnessPal or Lose It at get-signal.app/import. Full micronutrient panels — potassium, cholesterol, vitamins A, C & D, calcium, iron — auto-filled from USDA and editable on every entry.
Log any workout with automatic calorie estimates based on your weight and MET values. Apple Health syncs in the background — no need to open the app — across dozens of workout types including strength, yoga, swimming, cycling, and more. Track consistency, volume, and type variety over time in the Trends tab.
Track weight, body fat percentage, and measurements over time. Signal uses body fat % — not BMI — to classify your composition. BMI has been removed entirely because it penalizes muscular people. Ranges are sex-specific and color-coded from Athletic to High.
Track consecutive days hitting your goals — protein target, no alcohol, no late dinner, steps goal, sleep score. Signal shows your current streak and your personal best so you can see momentum building over time.
See how sleep affects next-day readiness, how alcohol shifts your HRV, and whether late dinners hurt your sleep score — all visualized from your actual data across body, sleep, activity, and nutrition tabs.
Earn back a percentage of your active calories to raise your daily goal when you exercise. Choose 20%, 40%, or 60% add-back — capped at 600 kcal so big workout days don't inflate your budget unrealistically. Your calorie ring and remaining-calories display update automatically.
Triple-tap the Signal logo for a witty, data-driven roast of your recent health choices. Claude reads your last week of sleep, HRV, nutrition, and workout data — then writes something brutally honest. Rate-limited to 3 roasts per day, because some truths are best in small doses.
The Today tab surfaces every metric that matters in one glance. Recovery scores from your Oura Ring, activity from Apple Health, and nutrition progress — all in one place when you wake up.
Signal grades your week like a teacher grades an exam — except the rubric is your own goals, not someone else's standards. Grades are calculated server-side from your actual logged data, then Claude writes a narrative based on your numbers.
Signal has 90 days of your sleep, HRV, readiness, nutrition, and workout data — and Claude can actually read all of it. Ask any question and get an answer grounded in your real numbers, not generic health advice.
Add friends and see each other's daily health wins — calories hit, sleep score, steps, workouts, readiness. You control exactly what you share with each friend individually. A quick ping is all it takes to keep someone on track.
Connect your existing tools and start seeing patterns immediately. The more data Signal has, the sharper the insights get.
