iPhone and Mac usersApple Reminders
Free with every Apple device Apple Reminders is the built-in task and list app on Apple devices. It covers checklists, grocery lists, subtasks and Smart Lists, with time and location alerts, Siri, shared lists and iCloud sync. It is included free on iPhone, iPad, Mac and Apple Watch, and you can reach it on the web too.
Pick it if everyone in your home uses Apple devices and you want shared lists without another app.
Also consider: the free plans of TickTick and Todoist, if you want more features and don't mind an upgrade prompt.
Microsoft To Do is the best all-round free choice because it runs everywhere and includes a daily planner. Google Tasks is the natural pick for Gmail users. Apple Reminders is hard to beat if you are fully on Apple, especially for shared family lists.
