How it works

Three steps to more clarity

Reflux has many faces – and different triggers for everyone. FluxFree makes yours visible.

  1. Log

    Record meals, symptoms, triggers, medication and sleep in seconds – by search, barcode scan or quick access.

  2. Understand

    The dashboard shows your daily reflux risk, detects recurring patterns and reveals the link between what you eat and how you feel.

  3. Adjust

    With the 4-phase plan you test foods deliberately and build a personal food profile – without unnecessary restrictions.

Features

  • Traffic-light scale: low (under 35), moderate (35–70) or high (over 70)
  • Pattern detection: if heartburn keeps occurring after large meals, FluxFree points it out
  • Daily goals for calories, carbohydrates, fat, protein, fibre and sodium
  • Daily timeline: meals, symptoms and triggers in one clear list

Eating plan

Important notice

If symptoms are persistent or severe, always talk to your doctor – and never change medication on your own.

FAQ

Frequently asked questions

The most important answers at a glance – you’ll find all the others in our FAQ.

What is FluxFree?

FluxFree is an app for people with reflux, heartburn and acid-related symptoms. You log meals, symptoms, triggers, medication and activity. From this the app calculates a daily risk estimate, spots patterns and guides you through a 4-phase plan, step by step, to your personal trigger foods.

Does FluxFree replace seeing a doctor?

No. FluxFree does not diagnose and does not give medical treatment recommendations. Its insights are a guide only and do not replace a medical examination, advice or treatment. Always discuss results, dietary changes and above all any changes to your medication with your doctor.

How is the Reflux Risk Indicator calculated?

The indicator shows how likely it is that you will get reflux symptoms such as heartburn or burping on a given day. An AI model calculates it from your logged meals, lifestyle factors (e.g. smoking, alcohol, stress), medication and sleep, as well as from your profile. The scale: under 35 = low, 35–70 = moderate, over 70 = high.

The value is a rough guide, not a medical measurement. Day-to-day fluctuations are normal. The more you log, the better the estimate can adapt to you.

What is the 4-phase plan “Adjust eating habits”?

A structured elimination diet that helps you reliably identify your personal trigger foods:

  1. Reset (2–3 weeks): a low-acid diet without the main triggers such as caffeine, alcohol, chocolate, mint, citrus fruit, tomatoes and fried or fatty food. Once your reflux score stays consistently low, phase 2 unlocks.
  2. Reintroduction & testing (2–4 weeks): you reintroduce one food at a time and log your reaction.
  3. Stabilization (3–4 weeks): tolerated foods return to your everyday diet while you keep an eye on your symptoms.
  4. My lifestyle (ongoing): you know your triggers, have your personal food profile and get support on the go – including a restaurant cheat sheet and a 3-day mini reset if symptoms return.

The plan does not replace medical or nutritional advice. If your symptoms are strong or persistent, talk to your doctor before you begin.

What does FluxFree cost?

You can try FluxFree free for 7 days. During the trial, creating community posts and custom foods is reserved for Premium; after the trial you need Premium to keep using the app. The subscription is billed through the app store – you will see the current price there before you buy.

Who can see my health data?

Your logs (meals, symptoms, medication, triggers, activity) are private and visible only to you. The only things that are public are what you publish in the community yourself – posts, comments and your username.
