Not only is WhatsApp the most used chat app in Brazil, it is probably the most used chat app in the world — it appears more-and-more on websites as another social media outlet. I think it is important for RTM to consider this as a method of notification.

Cmon guys. When is this going to be implemented?

The way i see this working is like a personal assistant through WhatsApp, you text to a bot "Remind me to pick up milk tomorrow at 6:00 or when I get to this store" and the bot will send you a message at that time or place telling you to pick up milk.

When you get a reminder, you can respond saying remind me again later and so

This should definitely done, it should allow users create tasks and communicate as if it is a personal assistant working for you
Me: Remind me tomorrow at 6:00 to call Mom
RTM: Reminder has been set for 6:00 tomorrow to call mom
RTM (at 6:00): Call Mom
Me: remind me in half hour
RTM: I'll remind you in half hour to call Mom
