Understand your supplement stack — not just the bottles in it. Suvo breaks supplements into their individual compounds, combines overlapping doses across your whole stack, and checks them against documented rules. Scan a barcode or photograph a label to build your stack. With Suvo you can: • See combined intake across multiple supplements • Find overlapping and duplicate ingredients • Review potential interactions and timing conflicts • Check published upper-intake guidelines where available • Run a full Stack Review • See findings relevant to your profile and stack • Track your daily routine, reminders and adherence Suvo shows its work Suvo does not just tell you that something was flagged. For supported findings, you can inspect the reasoning behind them: Your stack. The finding. The rule. The source. AI helps summarize your existing Stack Review and intake findings in plain language. The underlying checks come from Suvo's structured rule system. No ads. We do not sell your personal data. Suvo is designed to help you understand your supplement routine. It does not diagnose, treat, cure or prevent medical conditions and does not replace professional medical advice.

Stack Tender is the FREE supplement scanner and tracker you're looking for. Bottle scanning is incredibly accurate and the logging and reminder features are flexible. No ads. No in-app purchases. Fast, intuitive UI. Huge catalog of supplement information, including synergies, interactions and contraindications. This is the app for people who take their health supplements seriously. OPTIMIZED FOR IPHONE DUO Stack Tender is fully optimized for iPhone Duo. Every feature below is there whether the phone is open or closed, and the app keeps your place as it folds and unfolds. BUILD YOUR STACKS Group supplements the way you take them: a morning stack, a sleep stack, one for training days. Each entry carries its amount, the days it runs and the times of day, filled in from the catalog and yours to change. Add a note about why you started. Pause a stack when you stop and it leaves your day; switch it back on when you need it. SCAN A BOTTLE Point the camera at a product instead of typing it in: the front, the Supplement Facts panel and the directions. Every ingredient is read off the label with its amount and matched to the catalog, the serving size and the directions become the entry's schedule, and the bottle goes into a stack as one entry counted in servings. You see what was read before it lands and can fix any line. Every bottle you have scanned is kept under Stacks, ready to add to another. SEE YOUR TOTALS Every stack adds up what it gives you of each supplement in a day, across its entries and the bottles in it, so the magnesium in a multivitamin counts beside the magnesium you take on its own. Tap a supplement to see every entry and product behind its total. CHECK OFF EVERY DOSE Today shows what is due, grouped by time of day. One tap logs a dose, or take a whole group at once. Log something extra you took off schedule, and finish yesterday if you forgot to. SEE HOW YOU ARE DOING A calendar shows every day kept, partial or missed, and how many days you kept over the last six weeks. KNOW WHAT YOU TAKE A catalog of over two hundred supplements, written for people who read the studies: the recommended dose and timing, whether to take it with food, dosage notes, synergies, interactions and contraindications, and the sources behind each one. Search by name or alias and add a supplement to a stack in two taps. REMINDERS Set the times of day your doses fall and get a reminder when some are due. SHARE AND IMPORT Make your profile public and share a stack; keep the rest private. Follow people whose stacks you like, star a stack to hear when it changes, and import one into your own, notes and all, to tune from there. A shared stack shows its totals too, and any supplement or product on it can go into a stack of yours from its row. Comment on shared stacks and articles. WORKS OFFLINE The app keeps what it has read and queues what you do, so a dose logged without a connection is sent when the connection is back. Stack Tender is free. Your stacks and your log are private unless you choose to share a stack. Stack Tender is a record of what you take, not medical advice; talk to your clinician about what is right for you.
