Reactions - Allergy Tracker
Track Triggers & Get Insights
Free
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.
