What's New in Marrow

1.6

October 28, 2026

The Export tab is now Connects, with three pages: Sources, AI and Exports. Sources shows every wearable and app sending data to Apple Health. Hevy and Intervals.icu now connect directly with a key. Free now includes 3 connections and Pro includes 20. Sources don't count toward either. Set an active calories goal in Goals. Lifts are sorted by what you log most. Hold an exercise in the logger to remove it. Bug fixes: an automation with nothing new to send no longer shows as failed, and raw-sample automations with a custom list of metrics now include sleep stages. Recently logged now shows every food in your diary, including barcode, photo, voice and AI meals.

One of the Best Health Tracking Apps I’ve Used!

I’m genuinely impressed with Marrow Health! I’ve been looking for an app that makes tracking my nutrition, fitness, and overall health easier, and this one has exceeded my expectations.

What really sets it apart is the ChatGPT integration. I can simply tell ChatGPT what I’ve eaten, including exact ingredient weights and nutritional information, and have my meals recorded in Marrow Health. The information then syncs with Apple Health, including calories, protein, carbohydrates, fat, fiber, sodium, and more. I’ve tested the integration, and it works beautifully!

I also appreciate the ability to track workouts, monitor progress, and keep my health information organized in one place. It’s especially useful for someone like me who is serious about losing weight, improving nutrition, and building muscle.

The app is clean, intuitive, affordable, and genuinely useful. It’s refreshing to find something that makes health tracking feel less like a chore.

I understand this is a relatively new app, and I sincerely hope the developer continues supporting and improving it for years to come. There’s tremendous potential here, and I’d love to see Marrow Health become a long-term success.

Thank you to the developer for creating something so useful. You’ve earned my five stars, and I’m excited to see what’s next!

Thank you for taking the time to write such a detailed and thoughtful review! It’s amazing to hear that the app has been working well for you and that you’ve been enjoying the new ChatGPT integration. While you’re right that we’re relatively new, Marrow Health is here to stay, and updates will keep coming to support you and all our users. Please reach out anytime if you have ideas for how the app could better meet your needs! 🙌

Great app

I have had great success with this app. I like being able to track my workouts week by week, so I know where I can bump up the wait. I like how easy it is to use. It is an awesome motivator for me.

Hey Huel! So glad to hear the workout feature has been working well for you. Feel free to reach out anytime if you have any thoughts on how it could be improved! 😀

Worth trying!

One of the better calorie tracking apps I’ve used. Would recommend to anyone trying to get a grip on their health and fitness

Response from developer

I appreciate the feedback, Jake! It’s great to hear that you’ve had a good experience with the app. Feel free to reach out at any time if there’s anything you think could make it better! 😎

So good I want to Pay

Honestly, this app is fantastic, I don’t personally have much use for the AI exports and MCP server configurations (yet), but i’m sure I will! This privacy respecting, no ads health/fitness tracking app is perfect for my needs of tracking my nutritional content! I’ve already submitted a potential bug report via the Email, so hopefully that gets resolved soon! Otherwise a truly top notch app! Would totally be interested or willing to partake in beta testing feature releases!
