Most supplement apps track what you take. Capsula shows you what actually changes. Log your vitamins and supplements, rate how you feel, and after 7 days Capsula reveals the personal patterns hiding in your own data. It is the difference between a checklist and an answer. WHY CAPSULA Other apps are input first. They are great at recording pills and reminding you to take them, but they stop there. Capsula is output first. The real question is not what you took, it is what happened to you. We turn your everyday logs into a clear, personal picture of which supplements line up with your best days. ONE TAP DAILY TRACKING Check off your whole stack in seconds. Tracking is built around a 3 second rule, so it never feels like a chore. Build a streak as you stay consistent, glance at an interactive week strip to fill in days you missed, and watch supplies with low stock reminders. A home screen widget shows todays doses at a glance, and core tracking works fully offline so you are never blocked by a weak connection. RATE HOW YOU FEEL Score your sleep, energy, and mood on a simple 1 to 10 scale with a quick daily check in. These three signals are the other half of the story. Without how you feel, a supplement log is just a list. With it, your data can finally show you something useful. YOUR PERSONAL CORRELATIONS This is the heart of Capsula. After 7 days of consistent tracking, we compare the days you took each supplement against the days you did not, using the same statistical method that clinical studies rely on. The result is plain English, for example how much higher your energy tends to be on the days you take a given supplement. Confidence grows as you log more days, and early signals are always labeled as preliminary so you know how much weight to give them. INSIGHTS THAT GROW WITH YOU Your Insights tab turns numbers into something you actually want to open. See your top supplements ranked by personal impact, compare this week to your past self, and follow a Weekly Pulse recap of your habits and standout moments that you can share. A Stack Score adds a light, motivating measure of how complete and consistent your routine is, with a clear breakdown of what moves it. BUILD AND MANAGE YOUR STACK Search a deep supplement database powered by the NIH DSLD to add products fast, or start from ready made and community stack templates. Run multiple stacks at once and set on and off cycling schedules for ingredients you take in phases. Every supplement has a detail view with ingredients, suggested timing, and an evidence level so you know what the research actually supports. CHECK INTERACTIONS AND NUTRITION Capsula flags potential supplement to supplement interactions so you can spot combinations worth a second look. A color coded daily nutrition summary shows how your intake stacks up against reference daily values, so you can see where you are covered and where you may be doubling up. SMART REMINDERS Set gentle, timing aware reminders for morning, afternoon, evening, and bedtime, matched to when you actually take each supplement. No guilt and no nagging, just a helpful nudge. ASK THE AI NUTRITION ADVISOR Have a question about your stack, timing, or an ingredient? Chat with an evidence based AI advisor for clear, balanced answers grounded in your own routine. SYNC ACROSS DEVICES Create an account to securely back up and sync your supplements, logs, and wellbeing scores across devices, or keep everything on device. The choice is yours, and core tracking always works offline. A NOTE ON SAFETY Capsula is for self tracking and personal insight only. It is not medical advice and is not intended to diagnose, treat, cure, or prevent any disease. Correlation is not causation, and the patterns you see reflect your own data, not proof of cause and effect. Always consult a healthcare professional before starting, changing, or stopping any supplement, especially if you take medication or have a health condition.
