About

Reactions helps you track allergy-related, skin, and breathing symptoms alongside potential triggers so you can understand your own health better. All features require a subscription at £4.99/month. TRACK YOUR SYMPTOMS DAILY Log reactions to foods, cosmetics, cleaning products, pollen and pollution. See patterns emerge over time with our intuitive daily tracker. SCAN PRODUCTS INSTANTLY Use your camera to scan product barcodes and instantly identify ingredients that may be affecting you. GENERATE PERSONALISED REPORTS Every 12 days, generate a summary report that highlights patterns between your symptoms and trigger exposures. MONITOR ENVIRONMENTAL FACTORS Stay informed about local pollen counts and air quality data relevant to your location. Reactions was built by a team who personally struggle with allergies and found it difficult to get timely support through the NHS, an institution we greatly admire. This app is designed to help users better understand their health while waiting for, or in between, professional care. SUBSCRIPTION INFO Reactions is a subscription-based app (£4.99/month). Payment will be charged to your Apple ID at confirmation of purchase. Your subscription automatically renews unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID Account Settings. This app is not a medical device and does not diagnose, treat, or prevent any medical condition. Always consult a qualified healthcare professional for medical advice.
