Best Activity Tracking Apps That Sync With Apple Health [2026]

Apple Health is quietly one of the best things about owning an iPhone. It’s a central repository for everything your body does — steps, heart rate, sleep, workouts, nutrition, reproductive health — pulled in from dozens of apps and devices, available in one place, owned entirely by you.

The catch: it only knows what you tell it. And if your go-to activity tracker doesn’t sync with Apple Health, you end up with a fragmented picture. Your workouts are in one app, your habit data is somewhere else, and Apple’s Trends feature — which spots patterns in your health data over weeks and months — can only work with what’s actually there.

Finding an activity tracker that syncs well with Apple Health closes that gap. Here’s what to know before picking one.

Why Apple Health Sync Actually Matters

Apple Health sync isn’t just about having data in two places. It’s about unlocking features that depend on having all your data in one place.

Apple’s Trends feature, for example, analyzes 12 metrics over rolling 90-day windows and flags when something is shifting — you’re sleeping less, your resting heart rate is trending up, your activity level has dropped. That analysis only works when Apple Health is populated with real data from across your life, not just what the Apple Watch picks up passively.

There’s also the composability angle. Apps like Apple’s own Health app, Sleep Cycle, and various medical tools can read and respond to data stored in Apple Health. When your activity logging app writes to Apple Health, that data becomes available to every other app in your ecosystem.

Two types of sync exist: read and write. A read sync means the app pulls data from Apple Health — useful for seeing your step count or heart rate inside the app. A write sync means the app sends data to Apple Health — what matters if you want your logged activities to appear in Apple’s Trends, Vitals, and third-party integrations. For an activity tracker, write sync is what counts.

5 Apps That Sync Well With Apple Health

Logly

Logly is a flexible personal activity tracker built for people who want to log more than just workouts. You can track custom activities across fitness, wellness, hobbies, and daily routines — and it syncs activity data bidirectionally with both Apple Health (iOS) and Google Health Connect (Android).

What sets Logly apart from most trackers in this space is breadth. Most Apple Health-connected apps are built around a specific category — workouts, nutrition, sleep. Logly lets you log anything: a cold plunge, a meditation session, a language study period, a long walk that isn’t technically a workout. All of it writes to Apple Health, which means Apple’s Trends feature has a fuller picture of your daily activity than it would from wearable data alone.

The app is private by default — no social features, no leaderboards. And Logly Pro includes an AI chat that can surface patterns across your logged data, separate from whatever Apple Health surfaces on its own.

Best for: People who want to log varied activities beyond exercise and have everything count in Apple Health. Pricing: Free; Pro subscription for AI features and advanced stats.

MyFitnessPal

MyFitnessPal has been syncing with Apple Health since long before most apps bothered. It reads and writes a wide range of data types: calories consumed, exercise calories burned, weight, water intake, and more. If nutrition tracking is central to your health routine, MFP is one of the more complete integrations available.

The sync goes both ways on most data types, though the depth of the integration has varied across iOS versions. The core loop — log food and workouts, have it reflected in Apple Health — works reliably. The app’s calorie database is massive, and the barcode scanner for food logging is faster than any alternative.

The downside is complexity. MyFitnessPal is a large, feature-heavy app with a premium tier that gates meaningful features. If you’re not actively tracking nutrition, much of it isn’t useful — and the friction is real.

Best for: People combining food logging with fitness tracking who want Apple Health to reflect both. Pricing: Free with significant limitations; Premium ~$20/mo.

Strava

Strava’s Apple Health integration handles workout data specifically: GPS routes, duration, distance, calories, and heart rate from connected sensors. It writes workout sessions to Apple Health automatically after you record them, and it can read Health data like heart rate to supplement GPS-recorded activities.

Strava is the dominant social platform for endurance sports — running, cycling, swimming, hiking. If you care about segment comparisons, route mapping, and community features, it’s the right tool. The Apple Health sync is solid but narrow. Strava logs workouts; it doesn’t log anything that isn’t a workout.

Best for: Runners and cyclists who want Strava’s community features and Apple Health integration for workout data. Pricing: Free; Strava Premium ~$8/mo for advanced analytics.

Bearable

Bearable is built for wellness and symptom tracking — it’s popular with people managing chronic illness, mental health, and general health monitoring. It reads a significant amount of data from Apple Health (sleep, heart rate, HRV, steps) and lets you layer manual logs on top: mood, symptoms, medications, energy levels.

The sync is primarily read-based: Bearable pulls from Apple Health rather than writing back to it. That limits its usefulness if you want your Bearable data to appear in Apple’s Trends, but for people who want Apple Health data to inform their wellness logging, it’s a thoughtful integration.

Best for: People tracking symptoms, mood, or chronic health conditions alongside passive Apple Watch data. Pricing: Free; Premium ~$8/mo.

Cronometer

Cronometer is a nutrition and micronutrient tracker with one of the more rigorous food databases available. Its Apple Health integration covers nutrition data — macros, micronutrients, water — and it can read activity data from Apple Health to factor burned calories into its daily targets.

Less mainstream than MyFitnessPal, Cronometer appeals to people who actually care about micronutrients and want accurate data. The sync works cleanly. It’s not a general activity tracker, but for people whose primary tracking need is nutrition with health data integration, it’s worth knowing about.

Best for: People focused on precise nutrition tracking with Apple Health integration for activity calories. Pricing: Free; Gold ~$10/mo.

What About Android? Google Health Connect

If you’re on Android, the equivalent ecosystem is Google Health Connect — a centralized health data hub that launched with Android 14 and is now the standard integration layer for Android health apps.

The same logic applies: an activity tracker that writes to Health Connect enriches the data available to Google Fit, Pixel Watch, and third-party apps that read from Health Connect. Logly supports Google Health Connect on Android, which means the same bidirectional sync works across platforms.

The Health Connect ecosystem is less mature than Apple Health — fewer apps support it, and the third-party tooling isn’t as developed — but Google has been investing in it steadily. If you’re on Android and want the same centralized health data experience that Apple Health provides for iPhone users, Health Connect is the path.

What to Actually Look For

When evaluating any activity tracker for Apple Health sync, the questions that matter are: does it write to Apple Health or just read from it, and which specific data types does it write?

Some apps claim Apple Health integration but only pull step count and heart rate into their own dashboard. That’s not meaningful sync from an ecosystem perspective. You want an app that pushes your logged data to Apple Health so it’s available to everything else.

After that, it comes down to what you want to track. Strava is excellent if your primary activities are GPS sports. MyFitnessPal is the right call if nutrition is central. For people tracking varied daily activities across fitness, wellness, and personal routines — everything from workouts to sleep to creative habits — Logly covers the widest ground while keeping the logging itself fast and frictionless.
