Compound is a science-backed wellness tracking app that reveals how your supplements actually affect your body — with data unique to you. Most people take supplements on faith. Compound changes that. By combining daily check-ins across four wellness domains with your supplement routine, Compound builds a personalised picture of what's working and what isn't — based on your own biology, not population averages. HOW IT WORKS Every day, Compound asks you a short set of questions about how you feel across four domains: skin and beauty, cognitive performance, energy and recovery, and gut and metabolic health. Over time, it correlates your check-in scores with your supplement intake to surface insights that are genuinely personal. WHAT YOU GET — Domain scores that track your wellbeing across skin, mind, energy, and gut — Supplement correlations that show which products are moving the needle for you — A timeline of your progress with confound tracking (sleep, stress, alcohol) to keep results honest — Label scanning to instantly identify what's in any supplement — A curated product library with full ingredient transparency BUILT FOR PEOPLE WHO TAKE THEIR HEALTH SERIOUSLY Compound is for people who already invest in their health and want to know if it's working. Whether you're taking collagen for your skin, adaptogens for focus, or probiotics for digestion — Compound tells you if the data supports it. Your data stays yours. Export it anytime, delete it anytime. No ads, no data selling, ever. https://www.trackcompound.com/terms Compound Premium Premium Yearly: £79.99 per year (£6.67/month), auto-renewing Premium Monthly: £9.99 per month, auto-renewing 7-day free trial for new subscribers Payment is charged to your Apple ID account at confirmation of purchase.
