Which app connects sleep, nutrition and training on iPhone?

Ecleptic is our app; this comparison sticks to each brand's public information, linked in the sources below, checked on September 30, 2026.

"Connecting" can mean three things

• Side by side: seeing your night, your meals and your workouts in the same app.
• Correlating: logging a behavior (alcohol, a late dinner, calories) and seeing, over the weeks, whether it lines up with better or worse recovery.
• Integrating: making food part of the daily score calculation.

This is not a ranking: the table shows what each app's official pages describe.

The feature table

Whoop and Oura: the sensor first

Whoop and Oura measure your night with their own device. Their daily score rests on your heart, sleep, temperature and, for Oura, activity; food is not among their published signals. Whoop connects it through correlation: its Journal offers nutrition behaviors (calories, protein, carbohydrates, hydration and more), can receive them from other apps via Apple Health, and its Behavior Insights measure their effect on your recovery once you have 5 "yes" and 5 "no" answers within 90 days. Oura offers Meals: you photograph or describe your meal, an AI-assisted analysis rates its protein, fiber, added sugars or processing level (low, moderate, high), and your meals appear on a 24-hour clock next to your sleep and wake times. Meals requires an active membership and is currently available in English only.

Athlytic and Apple: it all starts with Apple Watch

With watchOS 27, Apple Watch Series 12 and Ultra 4 already calculate a readiness score combining activity, vitals and sleep, and the Health app brings together data from other apps. Athlytic reads that data from Apple Health: its Recovery compares your overnight HRV and resting heart rate with your baseline, its Journal shows how caffeine, alcohol or travel affect your recovery and sleep, and its trends display energy consumed and burned.

MyFitnessPal and Yazio: the plate first

MyFitnessPal describes a calorie and macro log with an AI coach, workout and step logging, and connections to more than 40 devices and apps; barcode and meal scanning are part of Premium. Yazio describes an AI-assisted calorie counter with a barcode scanner, intermittent fasting tracking and built-in step and activity tracking; syncing with Fitbit or Garmin is part of Pro. Neither listing mentions a recovery score or sleep tracking.

Ecleptic: food inside the daily score

Ecleptic integrates: your nutrition is worth 21 points out of 100 in your Readiness Score, alongside overnight vitals (42), sleep (21) and rhythm with training load (16). You photograph your meal (up to 3 photos), scan a barcode or search for a food: the AI recognizes the foods and estimates portions, while the values come from official databases (the ANSES Ciqual table, USDA FoodData Central, Open Food Facts). The pillar looks at how well you hit your targets, post-workout protein, micronutrients and hydration, and it is capped at 80 if you drank alcohol the day before. The details: the nutrition method.

How to choose based on what you already have

• An Apple Watch Series 12 or Ultra 4: the readiness score is already on your watch; an app that reads Apple Health can add a journal or your meals.
• A Whoop: check that your food app writes to Apple Health, which is where Whoop imports nutrition into its Journal from.
• Counting calories above all: that is the core of MyFitnessPal and Yazio.
• Wanting your meals to count in your morning score: that is how Ecleptic works.

Either way, Apple Health is where you choose, category by category, what each app can read.
