One connected picture
See the day as a whole.
Sleep, HRV, activity, meals, water, and weight come together in one personal context. Instead of isolated numbers, you see the signals that matter for the day you're actually having.

From a Lock Screen nudge to a logged meal — recorded in the shipping app.

Inside Grio
From scattered signals to one useful next step.
Logging is the input, not the point
Snap the meal. Keep the context.
A photo or a quick line is enough. Grio handles the log, remembers how it fits your goals and routines, and carries that context into the next useful suggestion.
Proactive by design
It notices before you ask.
When sleep, recovery, activity, or a long gap between meals moves away from your baseline, Grio can reach out first with a timely, realistic action for today.
What the app does
Main features.
Meal logging from a photo or a sentence
Photograph the plate or type a line. Grio identifies the food, estimates calories and macros, and files it under the right meal.
Apple Health, connected
Sleep, HRV, resting heart rate, steps, workouts, and weight sync in and become part of the same daily picture.
A coach that starts the conversation
Chat any time, or let Grio reach out when a signal moves — a short night, a hard session, a long gap since the last meal.
Daily condition check-in
A short morning check, pre-filled from the night that Apple Health already recorded, so the day starts from real numbers.
Missions instead of targets
Small commitments you can keep today, chosen from your own goals and adjusted as the week goes.
Fasting timer on the Lock Screen
Start an eating window and follow it from a Live Activity, without opening the app.
Daily and weekly recaps
A written read of what happened — what changed, what likely caused it, and what is worth carrying into tomorrow.
Long-range trends
Weight, sleep, stress, and activity over weeks and months, with the expected line your goal implies drawn alongside.
Why Grio
Health data should do more than describe the past.
Grio closes the loop: observe the day, understand the context, notice the pattern, act at the right moment, and learn from what happened.
It connects causes, not just scores
Grio looks for repeated relationships between your routines and how you feel, so health data becomes an explanation you can actually use.
It acts while the choice is still yours
A chart reviewed at the end of the week is too late. Grio turns signals into a suggestion while there is still time to adjust the next meal, workout, or bedtime.
It becomes more personal over time
Your goals, constraints, preferences, conversations, and history stay connected. The longer you use Grio, the less its guidance feels generic.
