Squiggle - Your Lists Sidekick Squiggle is the beautifully designed list app for everything: groceries, tasks, packing lists, wishlists, and whatever else is living rent-free in your head. Built with a hand-drawn, doodle-style feel that makes organising actually enjoyable. AI-Powered Features Let AI do the heavy lifting. Magic Add turns a quick thought ("dinner party for 8") into a full, organised list in seconds. Smart Sort groups your items by category so you move through a store without backtracking. AI Create builds an entire list from a single prompt. Lists, Your Way Create lists with custom emoji, pastel colours, and a hand-drawn card design. Star your favourites to pin them to the top. Archive lists you don't need right now; they're always there when you do. Save any list as a reusable template. Reminders That Actually Work Set a time-based reminder or a location reminder that fires when you arrive near a store or place. Squiggle uses geofencing so you never forget the one thing you needed to pick up on the way home. Collaborate in Real Time Share any list with friends, family, or teammates. Collaborators see changes instantly. Get push notifications when someone adds or checks off an item, without the noise of every single update.
