He now says he is willing to proceed with his original plan to buy the social media company for $44 billion, saying that: "Buying Twitter is an accelerant to creating X, the everything app."

So, what exactly is he talking about?

A super app, or what Musk refers to as an 'everything app', has been described as the Swiss army knife of mobile apps.

It offers a suite of services for users such as messaging, social networking, peer-to-peer payments and e-commerce shopping.

These mega apps are already widely used in Asia.

That's because mobile is the main form of access to the internet for many people in the region, experts say.

An example of such a super app is China's WeChat.

It has more than 1 billion monthly users, according to one estimate.

WeChat is a ubiquitous part of daily life in China.

Users can hail a car or taxi, send money to friends and family or make payments at stores.

In 2018, some Chinese cities even began testing WeChat for an electronic identification system that would be tied to users' accounts, according to the South China Morning Post.

Another example is Grab, a leading super app across Southeast Asia.

It offers food delivery, ride-hailing, on-demand package delivery and financial services and investing.

So, why does Musk want to make one?

During a question-and-answer session with Twitter employees in June,

Musk noted there was no equivalent to apps like WeChat outside of Asia...presenting him with an opportunity.

Adding more tools and services to Twitter could also help Musk reach his lofty growth goals for the company.

Musk said he wanted Twitter to grow from its 237 million users to quote "at least a billion"

Snapchat parent Snap Inc previously introduced peer-to-peer payments called Snapcash.

But they ended the feature in 2018.

It also made a push into mobile gaming and recently ended that venture too, as part of cost-cutting plans.

Meta Platform Inc's Facebook and Instagram have also tried to expand beyond social networking and messaging into e-commerce.
