Read full description

Reflux Radar helps you track what you eat, log how you feel, and uncover which foods may be driving your acid reflux or GERD โ€” without the faff of manual food databases. LOG A MEAL IN SECONDS Just type what you ate in plain English โ€” "cheese toastie and a black coffee" โ€” and Reflux Radar's AI instantly breaks it down into ingredients, flags acidic foods, and gives each one a colour-coded pH rating. No scrolling through database lists. No barcode scanning. KNOW WHAT YOU'RE EATING Every ingredient gets an instant green, amber, or red rating based on its acidity level. Common reflux triggers โ€” coffee, tomatoes, chocolate, citrus, garlic, alcohol โ€” are flagged separately so you never miss them, regardless of pH. TRACK YOUR SYMPTOMS Log heartburn, bloating, regurgitation, nausea, or any other symptom in a few taps. Rate severity, add notes, and record good days too โ€” "I feel fine" is a data point. FIND YOUR PERSONAL TRIGGERS Reflux Radar analyses the time between your meals and your symptoms to surface your own trigger patterns. Upgrade to Pro to unlock the full ranking, confidence detail, and the evidence behind each pattern โ€” because generic dietary advice is not the same as understanding what affects you. CLEAN AND CALM No social features. No ads. No streaks. Just a clear, focused tool that helps you understand your own body. PRIVACY FIRST Your meal logs and symptom history are stored on your device and belong to you. When you log a meal, the description text is sent to a secure server-side API for AI ingredient parsing โ€” it is not stored or shared. --- Reflux Radar is not a medical device and does not provide medical advice. pH values are approximate and for informational purposes only. Always consult a qualified healthcare professional before changing your diet or treatment.
