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.
