The Stack Core

Stack Core makes group expenses painless — trips, roommates, dinners, anything you split. SCAN RECEIPTS, SPLIT BY ITEM Photograph a receipt and Stack Core reads the line items for you. Assign each dish to whoever ordered it, split shared items, and let tax and tip follow automatically — proportionally or evenly, exact to the cent. EVERY KIND OF SPLIT Even splits, percentages, exact amounts, or full itemization. Save drafts privately until you're sure they're right. Set rent or subscriptions to repeat weekly or monthly. ADD ANYONE — EVEN WITHOUT THE APP Add people by name and start splitting immediately. When they join from your invite link, they claim their spot and their balance comes with them. SETTLE UP FOR REAL Stack Core computes the fewest payments to zero everyone out, then opens Venmo or PayPal with the amount prefilled. Mark payments and confirm when the money lands. STAY IN THE LOOP Push notifications for new expenses, payments to confirm, and people joining — each type mutable in settings. Comment on expenses when the hash browns need discussing. No ads. No selling your data. Your group's records stay your group's.
