Planini is the shopping list app for households, shared flats, families, and anyone who wants to plan together without clicking through overloaded task-management tools. Create households, share lists by invitation, and organize everything that needs to be bought or done. Items can be added with quantities, notes, and categories, then checked off, reopened, edited, or deleted. Categories help you move through the store faster: fruit, vegetables, bakery, cleaning, frozen food, or your own custom order. Even a full weekly shop stays clear and easy to manage. Planini is intentionally simple: • shared households and multiple lists • categories and custom list order • quantities and notes for each item • favorites list for quick access • invitation links for planning together • live updates when several people use the same list • passkey sign-in instead of passwords • Apple Watch app with quick access to your lists • Apple Watch complication for quickly adding a default item Planini is not only for shopping. Use the same clear list workflow for household tasks, packing lists, errands, weekend planning, or recurring things that do not belong in a complex project-management system. Why Planini? Because a good list has to be fast. Open it, add an item, check it off, done. Planini focuses on everyday use: fewer distractions, clear structure, quick interaction, and sign-in without a traditional password. Planini requires an account. Sign-in uses passkeys. For shared use, you can create households and invite other people.
