inside the app
The full app is always there when you want it.
Move seamlessly from the conversation to today’s dashboard, history, recipes, or coach.
Today
Calories against target, macro bars, and every meal broken out with one-tap add or delete.
History
Seven-day calorie bars against your target, a logging streak, and a weight trend with your goal range shaded.
Coach
Describe a meal or snap a label — the coach does the arithmetic, logs it, and can save it to your library.
features
Everything a serious cut or bulk actually needs.
Coach-led targets
A short conversation about your stats and goal, then confirmed daily calorie and macro targets you can override any time.
Photo label reading
Snap a nutrition label and the coach extracts the macros, saves the product, and keeps only a small thumbnail.
Meal-by-meal logging
Breakfast, lunch, dinner and snacks tracked separately, with prev/next day navigation and back-dated entries.
Your recipe library
Meal preps, dressings and staples saved once with their macros, then logged in a tap whenever you eat them.
Share only what you choose
Everything is private until you flip a recipe or product public — then anyone can copy it into their own library.
Trends that mean something
Weight plotted with printed values and a shaded goal band, so progress is readable on a phone at a glance.
how it works
Set up once, then track your way.
- 1
Tell the coach your goal
Weight, height, activity and the target you want. It proposes calories, protein, fat and carbs with the reasoning.
- 2
Log by talking or by photo
“Chicken shawarma bowl and a shake” or a picture of a label. No searching a database of 40,000 near-matches.
- 3
Watch the line move
Daily bars, a streak, and a weight trend against your goal band tell you whether the plan is actually working.
faq
Questions worth asking.
- Is my data private?
- Yes. Entries, weigh-ins, chats, recipes and products are scoped to your account and invisible to everyone else unless you explicitly mark a recipe or product public.
- Do I need my own AI key?
- No. The coach is built in — there is nothing to configure and no separate AI subscription to buy.
- Can I share recipes with someone?
- Flip a recipe or product to public and it appears on the Browse tab, where anyone can copy it into their own private library. Copies never link back to your account data.
- Does it work on my phone?
- MacTracker is mobile-first: single-column screens, a bottom tab bar, and charts that print their values so you never need to hover.
- How does MacTracker work inside ChatGPT or Claude?
- Connect your MacTracker account once, then ask naturally to log a meal, check your day, record weight, estimate food, or review progress. MacTracker can show interactive choices and results directly in the conversation.
- Do I need a ChatGPT or Claude subscription?
- MacTracker includes its own coach. Using MacTracker inside another assistant depends on that assistant supporting custom connections and may require a plan offered by that provider.
