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.

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. 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 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. Start with a simple to-do list, add lists of goals, books to read, and groceries to buy, create reminders for payments, appointments, and classes, or track work and school projects - the sky is the limit. It’s a daily planner, task manager, and to-do list in one. This colorful, beautifully designed app is simple to use yet packed with some excellent features.
