How ChunkTrack works: getting started, your plan and goals, logging meals and workouts, your journey, your team and your data.
ChunkTrack: AI calorie & workout tracker. Log meals and workouts in seconds. Team up with your friends to take down the Chunk.
The Chunk is the character in the app, the one you take down. ChunkTrack is the app. Log it and watch the Chunk react.
ChunkTrack is on iPhone and Android. Download it with the App Store or Google Play badges on this site, or search "ChunkTrack" in the App Store or Google Play.
Sign up with an email address and password, or continue with Google on iPhone and Android, or Sign in with Apple on iPhone. Email sign-ups confirm their address before signing in. ChunkTrack is for adults aged 18 and over.
Your age is part of your calorie plan. ChunkTrack stores only your birth month and year and works your age out from them, so your plan stays accurate as the years pass. The day of your birth is never asked for.
Two short steps. THE BASICS: name, username, birth month and year, sex, and an optional photo. THE NUMBERS: height, start weight and goal weight. Then choose QUICK START to use sensible defaults, or CUSTOMISE GOALS to set your activity level, daily steps, weekly target, macros and water yourself. Everything can be changed later in Profile & Goals.
Every plan starts with a 7-day free trial. After the trial, in the UK, it's £39.99 a year on the annual plan, or you can pay monthly. You choose your plan when you sign up, and the App Store or Google Play shows the price in your currency before you confirm.
No. ChunkTrack starts with the 7-day free trial, then continues on the annual or monthly plan.
Yes. A friend's invite code, CHUNKFRIEND, gives 10% off your first year on the annual plan. Enter it on the plans screen when you sign up.
In the app, open the menu, go to Account, then MANAGE PLAN to see your plan, switch between annual and monthly, or cancel. Plans are managed by the App Store or Google Play, depending on where you signed up.
Tell ChunkTrack where you want to be, and it builds the plan for you. Your target starts from your body's estimated resting needs, adds a baseline for daily life, the calories in your daily step goal and your activity level, then sets a daily deficit or surplus from your weekly target. It updates when you edit your goals or log a new weight, and a new target applies from that day on.
No. A weight loss target never goes below a safety floor based on your resting needs, with a minimum of 1500 calories for men and 1200 for women. If your details put you in the underweight range, ChunkTrack won't set a deficit at all and points you to support.
Choose LEAN MACHINE, BALANCED WARRIOR or LOW CARB BURNER, or CUSTOM SPLIT to set your own protein, carbs and fat percentages. On Fuel, switch the top card to MACROS to see each one filling against its target through the day.
Yes. Set a goal weight above your start weight and your plan adds a daily surplus instead of a deficit. Your weight change shows as GAINED, and it only turns red if you move away from your goal.
Your plan holds you at maintenance, and you earn the GOAL WEIGHT REACHED achievement. Set a new goal any time in Profile & Goals.
Yes. Weight in kg or lbs, height in cm or feet and inches, and distance in km or miles. Change them any time in Profile & Goals.
Yes, both, any time. Your username is how friends find you; change it in Profile & Goals or in Account. Your profile photo can be taken, chosen, cropped or removed.
CALORIES REMAINING: your daily target, minus what you've eaten, plus any EXTRA you've earned by moving more.
Your target already includes the calories from your step goal and activity level. EXTRA is only the activity beyond that, worked out once for the whole day, so nothing is counted twice.
You've gone more than 5% past your target for the day, including any EXTRA. Tomorrow starts fresh.
A day counts towards your streak when you log a meal, a workout, a weigh-in, steps or water. If you haven't logged yet today, your streak still shows yesterday's count, so today is still yours to win. Steps and weigh-ins that sync in automatically don't count towards the streak; workouts from your watch do.
Yes. The WATER card on Today has quick-add buttons from 250ml to 1L and an undo if you tap one by mistake.
Set your WEIGH-IN SCHEDULE to daily, weekly or a custom date. When a weigh-in is due, ChunkTrack opens the weigh-in screen so it takes seconds. You can also weigh in any day from Journey.
TYPE IT, SAY IT, SNAP IT, SCAN IT and FIND IT. Open breakfast, lunch, dinner or snacks on Fuel and choose how you want to log it.
Just write it like you'd say it. The AI turns "two eggs on toast and a coffee" into a fully logged meal.
Describe it out loud. "Full English Breakfast" is a logged meal by the time you've said it.
Point your camera at your plate. ChunkTrack's AI reads the meal and logs the calories and macros for you.
Scan the barcode on the pack. ChunkTrack looks it up in Open Food Facts, a database of millions of products, and shows the full nutrition. Set your portion and log it.
Search a database of millions of foods and log it in seconds. Full nutrition, your portion, done. No AI usage, no limits.
No. Describe the meal in plain words, say it or snap it, and the AI estimates the calories and macros for you.
Yes. Every AI result opens on a review screen before anything is saved. Change the quantity of each item, remove items, add foods from the database or rename the meal, then tap LOG MEAL. Logged meals can be opened and edited or deleted later.
Yes. RECENTS on Fuel shows your recent meals. Pick one to log it again.
Yes. Open the day in Journey and tap + to log meals and workouts for that date.
You get 10 AI uses a day, shared between meals and workouts, and a DAILY AI USAGE card shows where you are. Find It and Scan It don't use AI, so they have no limit, and neither do quick log and GPS workouts. If an analysis fails on our side, no AI credit is used.
Yes. Meals, workouts, weigh-ins, steps and water save on your phone and sync when you're back online. Type It, Say It, Snap It and Find It search need a connection, and the app tells you straight away if you're offline.
Tap a workout type on Train, such as Running, Weights or Swimming, to quick log it with a duration and intensity. Or tap Describe It to TYPE IT, SAY IT or BUILD IT set by set, and the AI works out the details. Workouts earn calories back as EXTRA.
Add exercises one by one, as cardio, resistance or stretch, with sets of reps or time. Tap ANALYSE IT and ChunkTrack works out the calories, then review the workout and tap LOG WORKOUT.
Yes. Every AI workout opens on a review screen before it's saved. You can edit the details, the time and the calories, and edit or delete a workout after logging it too.
Choose Running, Walking or Cycling and switch on Track my route (GPS). ChunkTrack records your distance, time, pace or speed and elevation, with splits as you go, and keeps tracking with your phone locked. When you finish, you get your route card, splits and calories.
A picture of your GPS route on a map, made when you finish. Open it full screen or share it from your phone. If you share activity with your team, it appears on your workout in their feed. Your route card shows where you started and finished.
No. Walking and running workouts have a Counted in today's steps switch. Leave it on if your phone already counted the steps, and the workout keeps its full burn without doubling your day.
Yes. Activity beyond what your plan already includes is added to your day as EXTRA.
Weight trends, streaks, milestones and progress photos. Your whole journey in one place. On the tough days, it's the proof that you're winning.
WEIGHT CHANGE shows how far you've moved over ALL, WEEK, MONTH or YEAR. It turns red only when you move away from your goal.
Green: you logged food and finished at or under your target. Red: over your target. Blue: a workout with no food logged. Grey: a missed day. Tap any day to see its meals, workouts and weigh-in.
Tap LOG A WEIGH-IN in Journey for today or a past date. You can weigh in more than once a day and back-date a weigh-in you missed.
Add progress photos over time, including past dates. Use COMPARE to pick a before and an after and save a comparison. Your progress photos are private unless you choose to share them, as a post to your team or from your phone.
Twenty milestones, from your first meal to a 365-day streak. Once earned, they stay earned, and you can share each one with your team.
Go to MY TEAM, then FIND FRIENDS, and search their username or the email they signed up with. Tap ADD to send a request; once they accept, you're on each other's team. You can also share your invite link from the app.
If they signed up with Apple and chose Hide My Email, their account uses a private Apple address. Search their username instead.
Only your friends. There's no public feed, and people who aren't your friends see only your name, username and photo. Comments and reactions on a post can be seen by anyone who can see that post, and your friends can see your team list.
Workouts, meals, weigh-ins and step goals, posted automatically under your sharing settings, plus achievements you share and posts you write, with an optional photo. Filters narrow the feed to posts, workouts, meals, weigh-ins or progress photos.
You control what your Team sees. Your weight stays private unless you switch it on. Share Preferences has five switches: Streak, Activity, Meals, Weight and Antisocial. Streak, Activity and Meals start on, and Antisocial keeps you out of search. Turn any of them off and your friends stop seeing it, including past posts. Posts you write yourself are always shared with your friends.
Your team on one leaderboard. Hit your goals to take the top spot. LEADERBOARD ranks you and your friends on DAILY GOALS ACHIEVED, STEPS, WORKOUTS and DISTANCE, by week, month and year. Add friends to unlock them.
Tap React to add 💪, or long-press it to choose from 💪 🔥 👏 🐷 😂. Long-press a reaction count to see who reacted. Comment on any post you can see, reply to a comment, mention a friend with @ and react to comments too.
Yes. Block someone from their profile under MANAGE, and they can't find you, see your activity or reach you. Report a post with the flag or a comment with Report. Unblock any time from the BLOCKED list in MY TEAM.
Yes. ChunkTrack connects to Apple Health on iPhone and Health Connect on Android. Connect once and your steps, weigh-ins and workouts flow straight in. Connect from Integrations in the menu.
No. It's optional. You can log steps, workouts and weigh-ins yourself, and on Android your phone's own step sensor counts steps without connecting anything.
Yes. Workouts your watch saves to Apple Health or Health Connect after you connect flow into ChunkTrack and count towards your streak. ChunkTrack only reads from your health app; it never writes to it.
Four kinds, each with its own switch in Notifications: Weigh-in reminder, Social, Daily reminder and Achievements. All start on, and you can turn any of them off any time.
At most once a day, and only if you haven't logged a meal by the time you choose.
A Snap It photo is sent to our AI provider only to estimate the meal, and ChunkTrack doesn't store it. Your log keeps the numbers, not the picture.
Only while you're recording a GPS workout, including with your phone locked during that workout. The route is saved with that workout. No workout running means no location.
No. Your data is never sold, and the app has no advertising or tracking SDKs. The privacy policy sets out what's collected and why.
Yes. In the app, open the menu, go to Account, then MY DATA. We'll email you a download link, which expires after 24 hours. You can request one copy a day.
Open the menu, go to Account, then DELETE ACCOUNT and type DELETE to confirm. This permanently deletes your profile, posts, friends, workouts, meals, weigh-ins, goals and photos. Deleting your account doesn't cancel your plan, so cancel it in the App Store or Google Play too.
No. We can't give medical advice. Please speak to your GP. The health disclaimer on this site explains more.
