Cindla — Heartburn Tracker

Log a reflux flare from your wrist in two taps. Cindla is the first proper Apple Watch implementation in the GERD category — symptom-first, no food photo scanning, no AI ingredient analysis. WATCH-FIRST LOGGING - Tap the Cindla complication → tap Confirm. Two taps from raise to logged. - Or pick a quick-note from your eight most-frequent foods and drinks. - Severity slider on the Digital Crown. - Three complication families: circular, corner, inline. HONEST PATTERNS, NOT GUESSES - Frequency timeline (12 weeks). - Time-of-day heatmap. - Day-of-week distribution. - Trigger-strength bar chart — refuses to rank until you have at least 10 flares for that trigger. No misleading low-N rankings. - Severity distribution histogram. YOUR DATA, ALWAYS YOURS - CSV, PDF, and JSON export from day one — free, always. - HealthKit read-only for sleep, HRV, workouts. Optional cycle-data correlation if you already track in Apple Health. - Optional Acid Reflux entry written to Apple Health if you turn that on. - Everything stays on your device, syncs to your iCloud only. No backend, no servers, no analytics. ONE-TIME PRICING - 3-day full-access trial. - £6.99 unlocks Cindla forever. No subscription, no monthly charge. WHAT CINDLA IS NOT Cindla is a personal wellness tool, not a clinical product. It does not diagnose, predict or warn about reflux. It is not a substitute for medical advice — speak to your GP or specialist about anything that worries you.
