    What it is

    The client app for your nutrition, health & fitness journey

    CalorieScience Companion is the client-facing companion to the CalorieScience practice platform. Once your dietitian, nutritionist, health coach or fitness professional invites you to connect, everything they set up for you — meal plan, sessions, questionnaires and progress tracking — is available in a single app on your phone.

    Who it's for

    Built for clients working with a professional

    CalorieScience Companion is for individuals who are actively working with a nutrition, health or fitness professional, not a general calorie-counting app for the public.

    Clients following a plan built by a registered dietitian or nutritionist.

    How clients connect with their professional

    Your dietitian, nutritionist, health coach or fitness professional sends you an invitation from their CalorieScience account. Accepting it links your app to their practice, so your plan, sessions and messages stay in sync automatically.

    • Secure, invite-only connection to your professional
    • Book, confirm and reschedule sessions in the app
    • Review program invoices and payment status

    Meal plan access, always up to date

    Your meal plan appears in the app exactly as your professional built it, with meal timings, portions and macros. Whenever they update your plan, the app updates too.

    • Daily meals with calories, protein, carbs, fats and fiber
    • Recipe steps, ingredients and photos for every meal
    • Automatic updates when your professional revises your plan

    Track food, macros, symptoms and progress

    Log meals and macros against your daily targets, note symptoms between sessions, and watch your weight and biomarker trends move over time, so your professional always has the full picture.

    • Food and macro tracking against your personalized targets
    • Symptom notes your professional can review
    • Weight and goal progress charted automatically

    Upload lab reports in seconds

    Photograph or upload a lab report directly from your phone. Your professional can review your biomarkers, like glucose, HbA1c, thyroid markers and vitamin levels, and factor them into your plan.

    • Upload reports as a photo or PDF from your device
    • Biomarkers stay attached to your progress history
    • Shared only with the professional you're connected to

    Invoices and program details, on the go

    Keep track of invoices, payment status and your nutrition program details without leaving the app.

    • Review and download invoices from your professional
    • See your program, payment status and due dates
    Privacy & data security

    Your health data, protected

    CalorieScience Companion only shares your data with the professional you're connected to. Nothing you upload is visible to anyone else.

    Encrypted & access-controlled

    Your data and your lab reports are encrypted in transit and at rest, with access limited to your connected professional.

    UK & EU GDPR compliant

    CalorieScience is built to UK and EU GDPR standards. HIPAA compliance is in progress.

    Invite-only access

    You only appear in the app connected to the professional who invited you — there are no public profiles.

    CalorieScience Companion is a workflow and tracking tool that supports the guidance of your dietitian, nutritionist, health coach or fitness professional. It is UK and EU GDPR compliant; HIPAA is in progress. It is not a diagnostic tool, not a medical device, and does not replace clinical assessment by a qualified practitioner.
