Flare: Know Your Triggers
Food & Symptom Diary for IBS
Radically simple gastro diary that looks for patterns and potential food triggers
About Flare: Know Your Triggers
Flare is a radically simple gastro diary that tracks what you eat and how you feel — and finds the connections between them. Where existing food apps drown you in calorie counts and barcode scanners, Flare strips everything back to what matters: what did I eat, and how do I feel? Log a meal in under 15 seconds with free-text entry. Log symptoms with a quick tap grid. Once you have logged enough, Flare+ looks for patterns and shows the potential triggers it finds — as clean data cards, not a clinical report. Your diary is stored on your device. iCloud sync is optional and only starts when you choose it, and then lives in your private iCloud database. You can lock Flare with Face ID or Touch ID, optionally bring in sleep, activity and hydration from Apple Health to view alongside your symptoms, and delete everything in one tap, including the Health summaries Flare imported. Settings > Privacy lists what leaves your device. Flare is not a medical device and does not provide medical advice. For diagnosis or treatment, consult a healthcare professional.
