iPhone
Today's remaining calories and macros on one screen. Log meals, workouts and weight with an AI coach. Hearth Pro required; a free trial is available to eligible users.
Hearth is a health dashboard that brings meals, workouts and weight together with an AI coach.
SUBSCRIPTION REQUIRED
To use the features of this app, including logging meals, workouts and weight, the dashboard, goals and plan, and the ChatGPT and Claude connection, you need a paid Hearth Pro subscription (monthly or yearly). Downloading the app alone does not unlock these features (you can sign in and set your goal before subscribing). A free trial applies to eligible users; after it ends, the plan you chose is charged. See the purchase screen for the trial length, price and conditions. Subscriptions renew automatically and can be cancelled in your Apple Account subscription settings.
TODAY AT A GLANCE
See calories eaten, calories burned, what is left for the day, and your protein, fat and carbs (PFC) balance on one screen.
LOG RIGHT IN THE APP
Log meals and weight from Home. The medium-size Home Screen widget also opens "Log meal" and "Log weight" in one tap.
LOOK BACK ON YOUR MEALS WITH PHOTOS
Browse meal photos and estimated calories in a calendar. AI estimates can be edited or deleted later.
GOALS AND PLAN, MADE VISIBLE
See your weight trend, progress toward your goal, a projected finish date and milestones up to your deadline.
LOG FROM CHATGPT OR CLAUDE (Hearth Pro required)
Connect your Hearth coach to ChatGPT or Claude and log meals, weight and workouts just by talking. Get daily plans and adjustment suggestions based on your goal and latest data. A suggested change to your goal only takes effect when you tap Approve in the app. The connection requires a supported ChatGPT or Claude plan.
