Pillplexity helps you understand and keep track of your medications and supplements in simple, clear language. Point your camera at a prescription label to instantly see easy-to-read explanations of what your medication is used for, what it's commonly prescribed for, and the difference between brand and generic names. Add your vitamins and supplements too, and see what they're commonly used for. Pillplexity is designed to make complex drug and supplement information more accessible and easier to understand. When two things you've saved are known to interact — prescription, over-the-counter, or supplement — Pillplexity shows you an educational flag with a plain-language explanation. Every interaction entry is traceable to a public FDA label or NIH source you can check yourself. With Vitals, see your own Apple Health metrics — heart rate, sleep, steps, and more — right beside your daily medication log, with automatic Apple Watch support. Patterns shows simple averages of your own readings on days you logged a medication versus days you didn't, computed entirely on your device. The app uses publicly available FDA drug information and structured medical data sources to generate simplified explanations in plain language. Features - Scan prescription labels using your camera - Add vitamins and supplements from a curated built-in library - Get simple explanations of medications and supplements - Educational interaction flags across prescriptions, OTC medicines, and supplements — every entry cites its public source - Vitals: your daily Apple Health metrics beside your medication log (requires Pillplexity Pro) - Patterns: neutral averages of your own metrics on logged vs. unlogged days, computed on your device (requires Pillplexity Pro) - Understand brand vs. generic drug names - Keep your prescriptions and supplements organized in one place - Build a daily streak by logging what you take - Set an optional daily reminder to log your medications - Privacy-first: your medication list and health data stay on your device — no ads, no analytics, no data selling - No account required for general use; sign in only to subscribe Vitals and Patterns require a Pillplexity Pro auto-renewable subscription. All other features above are described in the app. Important Information Pillplexity is an informational tool only. It does not provide medical advice, diagnosis, or treatment recommendations.
