Varsity Stack is a supplement app for every athlete, at any level and in any sport. That includes athletes who are drug tested. It recommends supplements for your sport. It checks products against certification programs. It helps you take your stack every day. Varsity Stack is free. CHECK A PRODUCT • Scan a barcode, or take a photo of the front label. • See if a certification program lists the product. A match names the program. • No match means the product is not on the lists we check. It says nothing else about the product. • Read the ingredients on the label. BUILD YOUR STACK • Answer a few questions about your sport, your training and your goals. • Get supplement recommendations. Each one shows why it was chosen for you. • Search certified products by name. • Add a product from a link, or type it in. • Share a product page from another app to add it to your stack. TRACK EVERY DAY • Log each supplement with one tap. • Set morning, evening and follow-up reminders. • Keep a streak. The app suggests a streak goal that fits you. • Earn rest days. One saves your streak when you miss a day. • Earn awards and levels. FRIENDS • Add friends from your contacts, by username or with your link. • Follow each other and see each other's streak, level and awards. • Start a Friend Streak. Log on the same day to keep it going. • Send a nudge when a friend hasn't logged yet. WIDGETS AND SIRI • Home Screen and Lock Screen widgets show today's progress and your streak. • A Live Activity shows what is due. Log from it with one tap. • Ask Siri to log your stack. LEARN • Short lessons explain what each certification seal checks, and what it does not check. FOR TEAMS • Does your team use Varsity Stack? Join with your team code. • See the products your team staff recommends. • Get reminders and notes from your coach or dietitian. LANGUAGES • The app follows the language of your phone: English and 30 more languages. GOOD TO KNOW • Certification programs are independent. They test supplements for substances that are prohibited in sport. • Certification lowers risk. It does not remove it. • Varsity Stack shows what the programs publish. It does not test or certify products. • Varsity Stack does not give medical advice. Terms of Use: https://varsitystack.com/terms Privacy Policy: https://varsitystack.com/privacy

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 — 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 — 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 — 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) — the same reference printed on your bottle — 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.
