Once you assign a task to someone, they get a notification on Karo if they have the app. Otherwise, the app first sends them a chat on WhatsApp, and if that fails, a reminder via text message.

Need help remembering things? Start using these to-do apps and never forget another important meeting.

A to-do list app called Twos is approaching this problem differently. When you add a task, it can suggest actions that might be relevant.

No matter what your goals are, there are apps that can help you plan your to-do lists more effectively and stay on track, like Todoist, Asana, and more.

These free to-do list apps will boost your productivity with everything from location-based reminders to giving you the ability to collaborate with others.
