Tonic
Read full descriptionHide full description
Tonic reads the clinical research on 201 supplements so you don't have to — and tells you the honest truth, including when something probably isn't worth your money. Most supplement apps either dumb the science down to star ratings or bury you in studies. Tonic does something different. It keeps two questions apart, because mixing them up is exactly how people get misled: • How SURE is the science? (Strong → Moderate → Limited → Early) • How BIG is the effect? (Notable → Little-to-none) So melatonin reads honestly: very certain science, but a modest effect. Creatine reads as strong evidence AND a real effect. And the trendy stuff reads as "interesting, but too early to say" — instead of a miracle. WHAT'S INSIDE • 201 supplements graded from the human research — vitamins, minerals, herbs, amino acids, probiotics and more • Plain-English summaries written for a smart friend, not a scientist • A study field behind every claim — see how many trials, and how many people, stand behind it • Scan any supplement label — the camera reads the ingredients and grades each one on the spot, entirely on your phone • Honest safety notes and clear "check with your doctor" flags • Build your stack and let Tonic optimise it — clashes to space apart (like minerals that block each other's absorption), when to take what, natural pairings, and gaps worth filling with the best-proven candidate • A 60-second quiz that grades what you already take — and finds an evidence-based starter stack • Share any verdict as a clean, honest card — including the "save your money" ones • Optional daily reminders for your morning and evening stack (everything stays on your phone) HONEST BY DESIGN Tonic is free. No ads. No account. It collects no data — everything stays on your phone. It exists to answer one question: is this actually worth taking? Tonic is educational and is not medical advice. Always talk to a qualified healthcare professional before changing what you take, especially if you take medication or have a health condition.
