What makes some apps “stick” while others fade away into obscurity? A great way to answer that question is to start by looking at the best mobile apps list on the market.

That’s why we’ve decided to catalog the top apps in 2021, highlighting a few of the features that make them stand out. This list will inspire you if you’re an entrepreneur with an app idea or a business leader looking to up your mobile game. It will also give you a sense of what works for some of the world’s top tech companies, so you can emulate their success.

The Most Important Lesson? Solve a Problem.

Whether you’re an entrepreneur with a new idea or a marketing leader trying to find better ways to serve your customers, all the best app ideas that follow have one thing in common. They use mobile technology to solve a problem. If you can solve a significant problem for a solid segment of the market, you’re in business.

With an ever-growing market, advances in technology, and evolving consumer demand, mobile applications help businesses stay relevant and competitive. The online magazine eMarketer found that the average US adult increased their time spent on mobile devices by 31 minutes in 2021, with 88% of their total mobile internet time spent inside apps.

In other words, the demand for mobile technology is strong and growing. The world loves apps and they’re willing to use them, but there’s a reason why most apps fail. If you want to ensure strong mobile engagement, you need to develop an app that solves a problem and delivers a phenomenal User Experience (UX). The following 10 top smartphone apps do just that.

What are the Most Popular Apps in 2021

To help you develop a mobile app that stands out from the competition, take a look at the top 10 trending apps of 2021 and see what they’re doing right.

Uber

Uber is the world’s leading on-demand ride-sharing service, connecting 103 million riders to drivers in over 70 different countries across the globe.

uber | most popular apps

Uber has plenty of competitors today, but they continue to dominate the U.S. Market, with 71% of that market share. They also have a powerful presence in most countries across the globe (their exit from Russia and China notwithstanding).

What made Uber so successful? Obviously, being first-to-market was a great advantage, but the app itself offers a superior user experience as well—something anyone can attest to when they’ve tried using local competitors in various parts of the world.

A few things the Uber app does right:

  • Excellent GPS integration with Google Maps, allowing users to drop pins in precise locations and giving them the option to make their location known to the driver.
  • Seamless payment processing, with the option to pay in cash in parts of the world where credit cards are less widespread.
  • Price calculation so riders know what they’re paying upfront. We’re all used to this by now, but this was an innovative feature when it launched.

Available on: iOS, Android

Price: Paid as per ride.

Instagram

One of the world’s largest social media platforms, with 1.4 billion monthly users, Instagram offers an easy way to connect through images and videos. Launched in 2010 and purchased by Facebook in 2012, Instagram is extremely popular among Millennials and Gen-Zers, making it a powerful channel for advertisers trying to reach those segments.

A few things the Instagram app does right:

  • The “stories” feature first appeared on Instagram before it spread to Facebook, making it easy to capture videos and photos that would automatically disappear within 24-hours.
  • In-app video and photo editing for on-the-spot uploads.
  • In-app shopping, allowing users to connect with brands they love and browse new products for sale.

Availability: iOS, Android

Pricing: Free.

TikTok

TikTok is a popular app, built by the Beijing-based firm ByteDance, for creating and sharing short videos. Among the most popular genres on the platform are lip-syncing and dancing, but many use it for highly-creative short films. Once the favorite among the under-18 crowd, TikTok has gone mainstream.

A few things the TikTok app does right:

  • A highly-effective algorithm figures out what users want to see, and it keeps them coming back. Sure, every social media site does this, but TikTok is “sticky” beyond belief—with the average user spending 52 minutes per day on the app, and with 90% of their monthly users accessing it daily.
  • Automatic filters that make everyone look a bit better looking on camera. Maybe this is not the best for teaching self-acceptance and body-positivity, but it sure does drive engagement.
  • Duets feature, allowing users to collaborate on different devices to create group videos. Since lip-syncing is all the rage on TikTok, this comes in handy with videos like this one, where users add on to existing viral videos.

Availability: iOS, Android

Price: Free.

Airbnb

Airbnb connects hosts who have apartments or rooms to rent with travelers who need a place to stay. Today a household name, Founder Brian Chesky struggled in the beginning, begging venture capitalists to invest $150,000 to keep it afloat—in exchange for 10% of the company. One of those VCs walked out of a coffee shop meeting with Chesky, convinced he was a mad man with a losing idea. Oops!

AirBNB

A few things the Airbnb app does right:

  • Powerful filters that make it easy to find the precise accommodation you want, down to details like whether the place has an iron to iron clothes or a desk to work from.
  • Easy in-app communication so hosts and guests can coordinate directly from the app.
  • Fully integrated payment system that includes the ability to pay for incidentals. For instance, if you lose the house keys and owe the landlord extra money for the copy they made, you can handle that exchange through the app.

Availability: iOS, Android

Price: Paid as per booking.
