The platform

Tracking. Planning. Coaching.

01
Track Meals Automatically
Members photograph their meals and get calories and macros instantly. No barcode scanning, no manual searching — just point, snap, and log.
02
Turn Goals into Personalized Plans
Generate weekly meal plans based on calorie targets, diet preferences, and restrictions. Every member gets a nutrition plan they can actually follow.
03
Give Coaches Real Nutrition Visibility
Provide trainers with adherence insights, nutrition summaries, and actionable coaching context — so they can coach on facts, not guesswork.

Tracking

Snap a meal. Get the macros.

Members photograph their plate and instantly receive a calorie and macro breakdown. The AI identifies individual ingredients, estimates portions, and logs everything automatically — no barcode scanning, no manual entry.

  • Photo-based meal recognition
  • Automatic calorie & macro estimation
  • Food logging without friction

  • Goal-based plan generation
  • Diet & allergy filtering
  • Meal swaps & plan regeneration

Coaching

Give trainers a real nutrition dashboard.

Turn food logs and plan adherence into actionable coaching insights. Trainers see which members are on track, who is struggling, and what to do next — without manually reviewing every meal.

  • Member adherence summaries
  • Calorie & macro trend views
  • AI-generated coaching prompts

Integration

Live in days, not months.

1
Connect the API

A single REST endpoint. Authenticate with an API key, send requests, get structured nutrition data back. Standard JSON — works with any stack.

2
Configure your modules

Choose which modules to activate — Tracking, Planning, Coaching, or all three. Each module works independently, so you can start small and expand later.

3
Launch in your app

Render the data in your own UI. Your brand, your design, your member experience — no gustar.io branding visible to your users.

Who it's for

Built for the teams behind fitness apps.

Gym Chains & Studios

Boost member retention with daily nutrition engagement

Give members a reason to open your app outside the gym. Meal tracking and personalized plans — delivered under your brand — create daily touchpoints that keep users active between sessions.

Fitness & Health Apps

Add a branded nutrition layer without building it yourself

Ship meal tracking, planning, and coaching features in days instead of months. Focus your engineering on what makes your app unique — let gustar.io handle the nutrition stack.

Coaches & Trainers

Coach nutrition at scale with real data

Stop relying on clients to describe what they ate. Get adherence summaries, macro trends, and AI-generated coaching prompts that make every check-in productive.
