Most acid reflux advice hands you a list of 40 foods to avoid. AcidLog does the opposite: it finds the 3 or 4 that actually bother YOU — so you can stop fearing the rest. Log a meal and how you felt in about 30 seconds. AcidLog's correlation engine compares each food with your other meals and names it as a likely trigger only when your symptoms keep following it — often within about two weeks for foods you eat regularly. Your personal trigger list is ranked by confidence. WHY A GENERIC "AVOID THESE FOODS" LIST FAILS Coffee wrecks one person and does nothing to the next. Reflux is personal. Instead of eliminating everything, AcidLog watches your own meals and symptoms and surfaces the patterns that are actually yours. HOW IT WORKS 1. Log — add a meal and rate symptoms (heartburn, regurgitation, throat, cough, bloating) in seconds. 2. Correlate — the on-device engine links foods to the symptoms that followed. 3. Discover — once a food keeps coming before your symptoms, it joins your ranked list of likely triggers, with a confidence score for each. Trigger foods you eat often usually show up within about two weeks; occasional ones take longer. WHAT'S FREE The full 14-day trigger discovery is free: log meals and symptoms and see your first correlations and trigger list. No trial paywall in front of the core. ACIDLOG PRO (monthly or annual subscription) - Your whole diary analysed, not just the last 14 days - Your full history stays viewable - Doctor-ready PDF report to bring to your gastroenterologist - Trends across weeks and months BUILT FOR REAL LIFE - Offline logging — entries save straight to your phone; with a free account they are backed up and sync when you're back online - No ads. Ever. - Fast enough to log at the table, not an hour later - Works for GERD, silent reflux / LPR, and post-meal indigestion MADE FOR - Adults with GERD or silent reflux (LPR), including long-term PPI users who want their own triggers, not another handout - Anyone newly diagnosed and told to "keep a food diary" - Caregivers who cook and want to know which meals set off symptoms AN HONEST NOTE AcidLog is a diary and correlation tool, not a medical device. It does not diagnose, treat, or cure any condition, and it isn't a substitute for your doctor. Its job is to hand you and your clinician better data. Find your triggers, keep your food. Start free.
