Calories come from your height, weight, age, sex and activity level: the Mifflin-St Jeor formula estimates what you burn at rest, scaled for how often you train, then adjusted for the weekly pace you picked. Change any of those in Profile & body stats and the targets move with them; if you set a target yourself, the app asks first. Protein is set from your weight and your macro split, and carbs and fat share the rest.
Your targets recalculate for your new bodyweight, so the pace you chose still actually happens, unless you set your calorie target yourself, by typing it or from What you actually burn: then it stays as you set it. Train's Progress tab charts the weigh-ins, and Home shows how far you are from your goal weight.
Mostly. Everything you log is written to the phone first, so your diary, your history, your routines, logging a food you have saved before and searching the 10,647 foods built into the app all work with no connection at all — and runs record by GPS, which needs none either. What does need the internet is anything that has to go and ask: searching for packaged and branded foods, scanning a barcode or a meal, the map drawing itself, and asking Health AI a question. Your run is still recorded while the map is blank. Anything logged offline is copied to your account the next time you open the app with a connection.
They use your phone's GPS. Expect a little drift under trees, between tall buildings, or in the first few seconds before the fix settles. Fixes that imply an impossible speed are discarded rather than added to your distance.
Because the app's own estimate is a guess. Only measured active calories from Apple Health can widen your budget, and only if you turned that on. Counting both would credit the same run twice.
A summary of your recent logs, so it can answer about you rather than in general: your targets and body details, what you've eaten, your workouts and routines, your water, your runs and walks, and your weight trend — and, from Apple Health if you allowed it, your steps, active calories and sleep. Never the maps of your runs. It can't see anything else, and nothing outside this app.
No. It's a coach built on general guidance, and it can be wrong. Anything medical — an injury, a condition, a medication, an eating disorder — is for a professional, not an app.
Settings → Export all my data puts everything in one file: your logs, your plan and body details, weigh-ins, saved foods and meals, routines, your own exercises and your coach conversation. Each section also exports its own, from its Settings tab: the runs you record as GPX, which Strava, Garmin and Komoot all import, and food and workouts as JSON.
If you are signed in, your food, workouts, runs, weigh-ins, water, saved foods and meals, routines, the exercises you made yourself and your plan are copied to your account, so signing in on the new phone brings them back. Your coach conversation is not copied — it stays on the phone you had it on. If you are not signed in, nothing is copied anywhere and the data goes with the old phone.
Your account and everything stored against it on our server, including the synced copies of your logs. Everything held on this phone is wiped at the same time.
