The app includes a handy My Day feature that lets you focus on the most important tasks you need to do today, as well as Cloud sync, so you can access your to-do lists, projects, and tasks from any device. The colorful tasks and lists not only look great, but they also have handy icons so you can categorize them to suit your needs, or add files and pictures as attachments to refer to later. The app itself is free, but upgrade to premium and you can enjoy features like Google Calendar integration, location-aware reminders, the Nag me feature, which helps you stop procrastinating with overdue tasks, and handy statistics to track your progress. Remember the Milk is a smart to-do app that lets you set up tasks and reminders, and then pings you via email, text, IM, Twitter, and notifications.

Use it to share your lists and assign tasks to others while keeping information synced on all of your devices. Customize your organization with priorities, due dates, repeats, lists, tags, and more. Search your tasks and notes, save your favorite searches as Smart Lists, and view nearby tasks to plan the best way to get things done. Remember the Milk integrates with Gmail, Google Calendar, Twitter, and Evernote. The app is free to download and use, but a Pro subscription for $40 per year lets you access additional features like subtasks, unlimited sharing, colored tags, mobile reminders, an Apple Watch app, unlimited storage, file attachments, and Microsoft Outlook syncing.
