Everything the app does, screen by screen — what each tab is for and what every button does. New here? Read top to bottom. Looking for one thing? Jump straight to it below.
Getting started
Luntrack is an all-in-one fitness companion: nutrition, training, cardio and a video PR leaderboard, tied together by the same account you use on this website and in the app.
Your account & onboarding
When you first open the app you set up your profile — age, sex, height, weight, activity level and goal (lose weight, gain muscle, maintain, or a custom target). From those, Luntrack calculates your daily calorie budget and macro targets. You can change any of it later in Settings → Goals & nutrition or on your Profile.
Free vs Pro
The core tracker — logging food, workouts, steps and weight — is free. AI features (photo food scanning, the AI chat coach) and some extras run on a subscription or on credits. Your plan is shown in Settings → Subscription. Subscriptions and credits are purchased on this website, never inside the app.
It works offline
Logs you make without a connection are saved on your phone and sync automatically when you're back online. A small banner tells you when you're offline or when changes are still syncing.
Home (Today)
Your day at a glance — body stats, activity and how your calories are tracking right now.
Your body — weight, height and BMI. Tap weight or height to update them; your weight change is tracked over time.
Steps streak — how many days in a row you've been active, pulled from Apple Health / Health Connect.
Today's energy — calories burned (from steps and workouts), eaten (from your food log) and the balance between them.
Macro ring — protein, fat and carbs against your targets. Tap it to review or, on Pro, set your own manual macro goals.
Explore — a shortcut into the leaderboard.
The number you should watch most is balance: it turns your goal (deficit for fat loss, surplus for muscle) into one simple figure for the day.
Nutrition
Log everything you eat and drink. There are five ways to add a food — pick whichever is fastest.
Search — type a food and pick it from the database (millions of products, including branded and international items). Choose a portion and log it.
Barcode scan — point your camera at a product barcode and the exact product's nutrition is filled in automatically.
PhotoAI — take or pick a photo of your meal and the AI estimates the foods and portions.
Ask AIAI — describe your meal in plain language ("two eggs and toast with butter") and it's logged for you.
Manual — enter calories and macros by hand when you already know them.
Portions & the quality score
Every food lets you set the amount — grams, a serving, or common household units. Foods also carry a Health Food Score: a per-100g quality rating (fibre, sugar, saturated fat, sodium and processing) so you can see at a glance how good a choice is, not just its calories.
Micronutrients & water
Beyond calories and macros, Luntrack tracks ten key micronutrients (vitamins and minerals) with a counters page and analysis. Log water with one tap to hit your hydration target for the day.
Budget, weekly view & saved meals
The top of the screen shows your daily budget — how many calories and how much of each macro you have left. The weekly view shows the whole week. Save meals you eat often as Your meals to re-log them in one tap, and track supplements you take.
AI tools
Luntrack's AI turns a photo or a sentence into a logged meal, and answers nutrition questions.
Photo analysis — recognises foods in a picture and estimates calories and macros, which you can adjust before saving.
AI chat — ask about foods, get suggestions, or say what you ate to log it straight from the conversation.
Credits & usage — AI actions use your plan's allowance or credits. Your remaining usage is shown on the nutrition screen and in Settings.
AI estimates are a fast starting point, not a lab measurement. Tweak the portion or macros whenever you know better — the app learns nothing wrong from a correction, it just logs what you set.
Training
A weekly workout plan you can build automatically or edit by hand, plus a technique guide and progress tracking.
Today spotlight — the top card shows what you're training today (or a rest day). Tap it to open today's workout.
Build the New You — the generator. Answer a few questions (days per week, goal, experience, equipment) and it creates a full weekly plan. Once you have a plan the same button becomes Rebuild.
Week list — every day of the week with its exercises. Tap a day to open it, add or remove exercises, and log your sets.
Exercise guide — open any exercise to see the muscles it works, a looping demo of the movement, and a one-tap YouTube technique search.
Progress graph — flip the Today card to see your training and body-weight progress over time.
Record a lift — film a set to keep for yourself or submit to the leaderboard.
Logging a workout
Inside a day, each exercise lists its target sets and reps. Enter the weight and reps you actually did — Luntrack keeps your history so the progress graph and streaks stay accurate. Rebuilding a plan is guarded once you have logged history, so you never wipe your record by accident.
Cardio
Steps, streaks and runs — most of it fills in automatically from your phone's health data.
Steps ring — today's steps against your daily goal, synced from Apple Health / Health Connect.
Streak — consecutive days you've hit your activity. Tap it to see every day in the streak.
Calories from steps — how much of your daily burn came from walking, and how many steps are left to your goal.
Runs & sessions — record a run or a cardio session and keep the history.
Cardio needs permission to read steps from Apple Health (iOS) or Health Connect (Android). If numbers look empty, grant access in your phone's Health settings.
Leaderboard & PRs
Post a verified video of a personal record and see where you stand against everyone else.
Submitting a PR
Adding a PR opens a short “How to film” guide — swipe through the example photos so your video counts: film from the side, keep the plates visible, no spotter, and capture the full lift. Then record the set.
Trimming your clip
After recording, the trim editor lets you cut your clip to the key 5–10 seconds. Drag the handles to set the start and end, tap play to preview, then Done. This page is locked to the editor — you leave it only with the Back or Done button so a stray swipe can't throw your clip away.
Verification & ranking
Submitted lifts are checked automatically before they appear, to keep the board honest. Once approved, your entry is ranked among everyone else. Tap any entry to watch its video.
Settings
Everything you can configure, grouped into cards.
Preferences — units (kg/cm ↔ lb/ft) and app language (20 languages).
Goals & nutrition — your current targets and how the daily budget is shown (including calorie rollover).
Follow Luntrack — links to our social pages.
Reminders — turn daily reminders on and set the time.
Media — whether photos you capture are also saved to your device.
Subscription — your current plan, top up credits, upgrade, or manage/cancel.
Appearance — background and visual options.
Data control — manage what's stored on your device (see below).
Session — sign out.
Help & Support — this guide, the FAQ (both open embedded in the app), and a way to contact us by email.
Legal — Terms and Privacy.
Data control
You decide what Luntrack keeps on your phone. Nothing here touches your account, and clearing local data just frees space — your synced data reloads from the server.
Temporary junk — safe-to-delete leftover files (image thumbnails, temporary copies). Clearing this only frees space.
Pick & remove — tick the items you want gone (cached data, AI photos, meal photos, saved meals, chat) and remove them all with one button.
Clear local data — wipes Luntrack's local cache and offline queue on this phone. Anything not yet synced is lost, so it warns you first.
Training data — clear your logged sessions, or delete your entire training plan. These act on the server and can't be undone.
Plans & credits
How the paid features work.
Where to buy
Subscriptions and AI credits are purchased on this website, from your account page. The app shows your current plan and links you to the right place; it never charges you inside the app.
Credits
Credits top up AI usage on top of your plan. They're handy if you run through your monthly AI allowance and want more photo scans or chat.
Managing your subscription
Upgrade, cancel, or recover a cancelled subscription from Settings → Subscription. If you cancel, you keep access until the end of the period you already paid for.
Support
Stuck, or something's not right?
Contact us
In Settings → Help & Support tap Contact us to email our team at support@luntrack.com. The same email sits next to Problems with subscription. You can write to us there any time.
Guides open inside the app
This Guide, the FAQ and the legal pages all open right in the app in an embedded window — no need to jump out to a browser.
