Designed around your real life

No tedious manual entries, no cookie-cutter plans.

Snap a meal

Calories and macros from one photo.

Take a photo of a home-cooked dish or a restaurant meal. Gemini identifies each item and estimates portions; totals are computed in code, so the math always adds up.

  • Per-item breakdown with portion estimates
  • Works with any cuisine, including Chinese dishes
  • Fix or undo any entry in one tap

Plans that adapt

A weekly plan built around your body and schedule.

Tell your coach your days, minutes, equipment and injuries. A workout planner drafts the week, a critic agent reviews it against your constraints, and you approve it before anything is saved.

  • Injury-aware substitutions, e.g. knee-friendly squats
  • Plan reviewed by a critic agent before you see it
  • Nothing changes until you tap Approve

Progress you can trust

See the trend, not the daily noise.

A 7-day moving average smooths out daily weigh-ins. Calories, protein and training are tracked against your targets, using the same numbers your coach uses in chat.

  • Weight trend over 2 weeks to 3 months
  • 14-day calories vs target and protein consistency
  • A weekly review of what worked and what to adjust

A coach that checks in

A coach that remembers, not just an empty log.

Fitness Buddy remembers your goals, preferences and past sessions. Open the app and it starts with what matters today: your workout, a protein gap, or a weigh-in.

  • Tips based on what you've logged today
  • Remembers your goals, injuries and food preferences
  • Answers in English or Chinese

Safety by design

Safety and guardrails

Layered checks from the first message to every saved change.

  • You approve every change

    Plans, calorie targets and deletions are saved only after you confirm.

  • Health guardrails

    Calorie floors (1,200 kcal women / 1,500 kcal men), max ~1% body weight loss per week, and red-flag symptoms routed to a doctor.

  • Prompt-injection shield

    Model Armor screens inputs and outputs, including text inside photos.

  • Private by design

    PII is redacted before storage, and each account's data is isolated.
