Capsula

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.

This is not a pill reminder. It is a ledger for the shelf: you type in what each supplement label says, and it adds the same ingredient up across every product you take. Six bottles. Three of them contain B6. Nobody tells you what that adds up to. WHAT IT DOES ⢠Type in a Supplement Facts panel once. The totals build themselves. ⢠Every ingredient shows how many of your products list it ā that number is the headline, not a percentage. ⢠Different names for the same thing merge automatically: Vitamin B6, Pyridoxine HCl and P-5-P all land on one line. ⢠Tap any line to see the breakdown: which bottle contributed how much. TWO THINGS THAT FALL OUT OF THE SAME DATA ⢠Cost: what each bottle works out to per day, and what the whole shelf costs a month. ⢠Run-out: how many servings are left and the date the bottle empties. BUILT FOR HOW LABELS ACTUALLY READ ⢠150 ingredients with their common label spellings built in ā including the mineral forms (magnesium glycinate, zinc picolinate, ferrous sulfate) that all report the same elemental amount. ⢠Anything not in the list is still accepted and still totalled. There is no "not found" screen. ⢠mg, mcg and g convert exactly. IU converts only where one factor is unambiguous ā for vitamin E and vitamin A the factor depends on the form, so the app keeps IU on its own line instead of inventing a number. ⢠Unlimited history, kept on the device with no time limit, and CSV export. WHAT IT DELIBERATELY DOES NOT DO It does not scan barcodes. It does not rate, rank or sell any product. It does not check interactions. It does not recommend a dose or an amount. It does not compare your totals to any limit. Percentages are arithmetic against the Daily Values the FDA publishes for supplement labels (21 CFR 101.9) ā the same reference printed on your bottle ā and nothing more is read into them. There is no account, no sign-up and no server. Everything is computed on your phone, which is also why it works with no signal at all. A "How we calculate" screen is open to everyone, free, with every formula written out. SUPP STACK PRO Pro is required to add products and record days. Reading, the "How we calculate" screen and CSV export stay free. ⢠A recurring subscription, with the first period at a reduced price ⢠Or a one-time purchase that never renews Subscriptions renew automatically unless cancelled at least 24 hours before the period ends. Manage or cancel in your Apple Account settings at any time.
