Lists are great for many occasions — top 10 action films, worthy cocktail bars, worst tinder dates (a particular long one of mine). Wunderlist is the king of to-dos, available on a wide range of platforms and devices. Featuring a very clean and simple interface, you’re able to quickly create lists about anything. Due dates and reminders can be set for individual items, along with optional subtasks, notes and attachments. Lists can be shared with others for collaborative viewing and commenting too, such as managing a communal shopping list. While the app is free, a subscription provides users with more advanced features.
