Fitness, sleep and food, in one calm view
Gradual turns what your Apple Watch and iPhone already know into one clear picture of your day: how you slept, how recovered you are, what you did, what you ate. Then it shows how that compares with you, not with everyone else.
Works with Apple Health and Apple Watch. Your data stays on a server you control.
Today
Open Gradual and you see how today is going: recovery, sleep, stress, what you have done and what you have eaten. Swipe to any other day. Each day in the strip is tinted by how it went, so a good week looks like a good week.
A week, at a glance
Colour and words always go together, so nothing depends on telling green from red.
Everything in one place
It reads Apple Health, so there is nothing to log twice. Whatever your Watch records, and whatever your food app writes to Health, ends up here.
Running, cycling, swimming, hiking, walking, climbing and strength training, each showing the numbers that matter for it: pace and cadence for a run, climbs and sends for bouldering. Heart rate and a route map for every outdoor session.
Sleep stages for every night, HRV, resting heart rate, breathing, blood oxygen and wrist temperature, each against your own normal. A recovery score and a stress indicator built from them.
Calories, macros and micronutrients from the food app you already use, against targets you set. Fasting worked out from your meal times, with a plan and a timer if you want one.
A target for a week, a month, a year or your own dates: distance, time, sessions, elevation or energy. See whether you are on pace, and what you need each day to finish.
All your walks, hikes and rides on one map, filtered by sport and year, with an elevation profile on each one.
Every session is compared with your previous similar ones, and every vital with your usual. Green means better, red means worse, blue means different, and a tap tells you why.
Compared with you
A heart rate of 52 means something different for everyone. Gradual learns your own baseline over a few weeks and tells you when something is better, worse or just different for you.
Recovery, stress and the day score are indicators built from your own readings. They are not medical measurements and not medical advice.
The shaded band is your normal range. Sample data.
Privacy
Health data is about as personal as data gets. Gradual is built so it stays yours.
Gradual stores your data on a server you run, not in a company's cloud. There is no account with us to hand your data to.
No analytics, no advertising, no third-party scripts. This page does not even load a font from anyone else.
The iPhone app asks for each kind of Health data separately and only reads what you allow. It never writes to Health.
Gradual shows information about your own numbers. It is not a medical device and does not diagnose anything.
