Common questions

How do I unlock everything? Stack Pro unlocks unlimited supplements, consistency stats and history, and the Home Screen widget. It is available Monthly, or Yearly with a 7-day free trial, or as a one-time Lifetime purchase.

How do I restore a purchase? Settings, then Restore Purchases.

Will it remind me to take my supplements? Yes. Stack schedules reliable reminders for each dose time, with gentle nudges if one slips, and a Home Screen widget that shows your next dose at a glance.

What is the living shelf? Each supplement sits on your shelf as its own bottle. It glows when a dose is due, dims when you take it, and empties through the day, refilling each morning, so one glance shows what is left and what is done.

Does my data leave my device? No. Everything stays on your device. Stack has no account and no servers.

Is this medical advice? No. Stack is a reminder and logging tool, not medical advice. Consult a healthcare professional about your supplements.
