You're going to the store anyway. Why not go for each other? CoterieShare turns everyday errands into small acts of love between the people who already care about you — your family, your neighbors, your church group, your friends. No strangers. No delivery fees. No gig economy. Just your people. HOW IT WORKS Go live when you head out. Tap the store you're driving to and your circle gets a heads-up: "Jeff is heading to Costco — ETA 30 minutes. Want anything?" They send their list. Milk, a prescription, that one thing they forgot. You check items off as you shop, right in the app — and your run lives on your Lock Screen so you never have to dig for your phone in the aisle. Settle up easy. Venmo or Zelle in one tap, with a thank-you tip if you're feeling generous. Or mark it "taking care of this one" — no total, nothing owed, just family. WHAT MAKES IT DIFFERENT Your coterie, not the crowd. Circles are private and invite-only — your family group, your street, your book club. Start one with a single group text: pick your people from Contacts and they're in the moment they sign up. My List. A private shopping list that lives inside the app. Type "milk @Costco" and it rides along on your next Costco run. Share it with your household so you both see the same list. When a friend heads to a store where you've tagged something, we ask if you'd like them to grab it. Surprise the people you love. Everyone keeps 5 Favorites — a go-to drink, food, treat, snack, and pick-me-up, each tied to the place it comes from. When you're standing in a friend's favorite spot, CoterieShare quietly taps you on the shoulder: "Grab their usual and surprise them?" They don't find out until it lands. It knows when you're there. Just drive to the store name — pull into any branch and your run follows you. Your circle sees when you've arrived, so nobody sends a request too late. Plan ahead. Posting tomorrow's grocery run tonight lets everyone add their list before you go. The coterie board. Pin the things you need but don't need today. Next time someone's out, they can grab it. Works on one bar of signal. Dead spot in the back of the store? The app opens instantly from its last good copy, and anything you add or check off posts itself when coverage returns. En español también. Switch languages any time from your profile. BUILT FOR TRUST Your chats, profile, address, and payment handles are visible only to your friends and circles — enforced on our servers, not just in the app. Location is used for one thing: noticing when you arrive at and leave the store you chose. It's never shared with your friends, and never used for anything else. Contacts are read only when you choose to invite someone, and only the people you pick are ever contacted. Go grab something for someone today.
