PearList vs Calcium Text Calculator

PearList keeps your household's shared lists in sync across everyone's phones, with no account, no server and no company in the middle. Make a grocery list, a to-do list or a chore board. Anyone in your household can add items, check them off, rename them, assign them and delete them, and every change syncs directly between your phones. Assign an item to a person and any list doubles as a shared chore board. There is no sign-up and no login. You join a household by scanning a QR code or tapping an invite link. From then on everyone sees and edits the same lists. Because PearList is peer-to-peer, your lists live only on your devices. They are never uploaded to a server, so no company can read them, sell them or lose them in a breach. Everything syncs encrypted, directly device to device. Features - Multiple shared lists per household: groceries, to-dos, chores - Add, check, rename, assign and delete items, synced to everyone - Assign items to a person to use any list as a chore board - Join by QR code or invite link, no account needed - Works offline, syncs when your devices are online together - Open source and private by design: no account, no ads, no tracking PearList is fully open source: https://github.com/peerloomllc/pearlist
