Stack Tender
Scan bottles, track your stack
Only for iPhone
Free
iPhone
Scan a bottle and its label is read into your stack. Build your stacks, check off each dose, and see the research behind every supplement.
Stack Tender is the system of record for your regimen: what you take, how much, when, and whether you took it today.
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.
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. 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.

- Search your products by what is in them, not only by their names.
- The Catalog's search shows every match as a supplement card, and each card says whether there is a dose to copy.
- Adding a supplement or a product to a stack opens a panel of cards. One tap adds it.
- Products on the Stacks screen is a search box and Scan. A product opens its editor full screen, with the stacks that hold it.
- Pickers, forms and lists rise as a panel. Tap above it or pull it down to lower it.
