Uber is the world’s most popular on-demand ride-sharing service, connecting 103 million users with drivers in more than 70 countries.

Uber has a lot of rivals these days, yet they still have a 71 percent market share in the United States. They also have a strong presence in almost every country on the planet (their exit from Russia and China notwithstanding).

What made Uber so popular? Being the first has advantages. Still, the app provides a better user experience something anybody who has used local rivals in different regions of the globe can testify to.

Here are a few things the Uber app does well:

Excellent Google Maps integration, enabling users to set pins in specific locations and choose whether or not to notify the driver of their position.

Payment processing is quick and easy, with the option to pay in cash in places where credit cards aren’t widely accepted.

Riders will know what they’ll pay upfront because of the price computation. We’re all accustomed to it now, but this was a groundbreaking feature when it first came out.


With 1.4 billion monthly users, Instagram is one of the world’s most popular social media networks. It provides a simple method to interact via photographs and videos. Instagram, launched in 2010 and bought by Facebook in 2012, is very popular among Millennials and Gen-Zers, making it a potent channel for marketers looking to target those demographics.

There are a few things that the Instagram app does right:

The “stories” function was initially introduced on Instagram before spreading to Facebook, allowing users to easily create films and photographs that would vanish after 24 hours.

For on-the-go uploads, there’s an in-app video and picture editing.

Users may connect with companies they like and discover new things for sale via in-app shopping.


TikTok is a popular software for producing and sharing short movies, developed by Beijing-based startup ByteDance. Lip-syncing and dancing are two of the most popular genres on the site, but many people also utilize them to make incredibly imaginative short films. TikTok, formerly the darling of the under-18 set, has gone mainstream.

There are a few things that the TikTok app does right:

It is a very successful algorithm that determines what consumers want to view and keeps them returning. Sure, every social networking site does it. Still, TikTok is unbelievably “sticky,” with the typical user spending 52 minutes per day on the app and 90% of monthly users using it regularly.

Automatic filters: make everyone seem a little more attractive on camera. Maybe this isn’t the ideal way to promote self-acceptance and body positivity, but it certainly gets people’s attention.

A duet is a tool that allows users to collaborate on group films while using various devices. Since lip-syncing is all the rage on TikTok, videos like this, where people add to previous popular videos, come in useful.


Airbnb links tourists who need a place to stay with hosts who have flats or rooms to rent. Founder Brian Chesky, who is now a household name, struggled at first, imploring venture investors to invest $150,000 in return for a 10% stake in the firm. One of those venture capitalists walked out of a coffee shop meeting with Chesky, convinced he was a lunatic with a bad concept. Oops!

There are a few things that the Airbnb app gets right:

Filters help you locate the exact lodging you’re looking for, down to the smallest details like if the apartment has an iron for ironing clothing or a desk to work from.

In-app communication makes it simple for hosts and guests to communicate straight from the app.

A payment system that is fully integrated and provides the opportunity to pay for incidentals. For example, if you misplace your home keys and owe the landlord money for the duplicate, you may conduct the transaction using the app.


Netflix is a video-on-demand service that requires a membership. It is the world’s most popular subscription Over the Top (OTT) media provider, available on various platforms, including smartphones. It is possible to find films and episodes representing many genres in Netflix’s vast library of films and episodes.

Netflix will have over 204 million paying customers by the end of 2020, and 47 percent of Americans prefer Netflix to any other video streaming service. With many of us under lockdown and yearning to escape into a world of movies as the Covid-19 epidemic carried on, users increased even further.

There are a few things that the Netflix app does right:

Suggestions: depending on what customers enjoy has helped Netflix keep viewers interested, but it has also resulted in a blooming of original Netflix TV series.

Offline viewing: allows users to download programs and movies to watch later on the subway or wherever else they don’t have access to the internet. We’re accustomed to it now, but there was a time when we could only broadcast material through a live connection.

Parental controls: Parents can restrict what material their children download on a family plan, and it’s all done via the app.
