What makes an app popular?

Forbes posted this Top 10 Apps by million downloads for the Second Quarter of 2021

Of course, what users want matters. So, the niche your app is into will affect your app’s following.

In October 2022 statistics recorded of downloaded apps from Apple by Statista, 12.68% of these downloaded apps were games, 10.35% business, 9.79% education, 7.93% lifestyle, utilities, 9.22%, food and drink 6.58%, and weather is the least downloaded with 0.3%.

On the Google play store, here are the most downloaded categories: communication: 99.93%; tools 99.81%; business 99.33; video players and edit 96.63 and weather as the last on the list with 32.36%.

While the data below was provided by Statista, based on the number of downloads (in millions) by leading Android Apps in the Google Play Store.

The Common Characteristics of Simple Apps that Made Millions

The App provides a solution to a problem, like Bubble Free and iAuditor.

The most profitable app ideas are those that answer a problem. Apps that make you hate Math a little less are flourishing. Singing apps that make you feel how it is to be in a studio, though you’re just singing through your mobile phone, are creating a vast market as well. Some apps make you pass the time while on a train, riding a bus, or waiting in line. There are just so many of them that help give solutions to our present situations.

“Our lives will be facilitated by a myriad of adaptive applications running on different devices, with different sensors, all of them collecting tidbits about everything we do, and feeding big digital brains that can adapt applications to our needs simply because they get to know us.”(Marcio Cyrillo, Executive Director, CI&T)

An example is iOS Bubble-Free from Falcon Mobile, which gives gratification to a very simple human habit. Most of us cannot help but exert the effort of popping bubble wraps!

Yes, a solution to an ordinary human habit, there you go! Bubble Free is, of course, free to download. But with millions of downloads and millions gained from advertising campaigns, it has made $7 million!

Another example of a helpful app that raised millions is iAuditor by SafetyCulture. It has so many great reviews for being simple to use, excellent functionality, security conscious, and not a single bad review!

The App sticks with “Simplicity is key’ like Draw Something and SoundHound

In a “fast-paced, ready-to-cook, real-time kind of world,” simple, user-friendly apps attract the most attention.

If your app can be navigated conveniently and has reasonable functionality, you may expect a considerable following. The user will not look for another app similar to yours because you already satisfy the most fundamental quality of world-famous apps – SIMPLICITY.

“The rich and interactive experiences we have come to expect on mobile apps have created new standards and expectations for all digital media, including the web. The result is websites are evolving to become more app-like in their rich functionality.” (Raj Aggarwal, CEO of Localytics)

One of the best examples is DRAW SOMETHING.

Draw Something by OMGPop, is an application that lets one play fun games by competing with other players. The game is to draw fast and finish it on time, with as many drawings as you can.

The App is High-performing, like Google Go for faster web search.

When your app is developed, it should right away show that it’s high-performing. What does this mean? The app must load fast, work fast, be continuously optimized, and ensure that the screen and in-app processes are consistently at an impressive speed, enough to secure successful user engagement.

“End users, not technologies, shape the market. Consequently, marketers need to stay abreast not only of technological developments but also of the way people respond to them.” (Matt Haig, author of Mobile Marketing-” The Message Revolution”)

Who wants to search using an app that is too slow to handle your mood? None, right? The app store is full of apps, but many of these do not deliver as promised. They almost always make you lose your temper.

Google Go is serving the right market, which is always satisfied with what it offers. Good reviews never stop coming in, and this is obvious just by looking at its $183.27M revenue for 2021.

The App must be available on iOS and Android. An example of a simple app that hit millions is Fat Booth.

If you want your app to reach the most comprehensive market, it should be available for both platforms.

In the United States, Apple iOS still holds the biggest market in smartphone operating systems, more than half of the market. (statista.com)

This means that to be a leading player in the market, you must hold both sides of the coin. Your app must be accessible to both platforms, iOS or Android. Anyway, cross-platform app development can help save costs for developers.

A cross-platform app is usually the best option for an MVP. An MVP or minimum viable product is an app with minimum characteristics or features that will serve as a test product to launch your idea and see if people like it. It may generate a million downloads in the App Store or Google Play Store.

Curiosity might kill the cat but not you. If you’re curious how you’ll look if you gain a few or more weights, then Fat Booth is your go-to App. And has been the app of millions of curious users that have made it earn $24 million in revenues.

The app must have security; a great example is WhatsApp Messenger.

Mobile devices are vulnerable to attacks on their security and privacy while transmitting and receiving information over the internet. Application security controls must be enhanced and programmed to be less susceptible to threats. Moreover, apps must undergo fuzzing to test various inputs to see why they react in such a way, which may lead to discovering a security hole.

Do you know that each time you turn on your mobile phone and use an app, you are revealing these things:

WhatsApp is a free, multi-platform messaging app used for video and voice calls, text message sending, sharing status, and more. It was launched in 2009 but purchased in 2014 by Facebook for $21.8B.

And speaking of security, what’s app has several advanced security features. Just like Apple’s iMessage and Signal, it has end-to-end encryption. This means that all messages going through it are secured, ensuring that only the sender and the recipient can view them. Even WhatsApp couldn’t read your message. Another good thing is, WhatsApp doesn’t store your personal information, and those in your contact list are the ones who may message you.

It also uses two-factor authentication like Google and Facebook.

The app must have a humanitarian value – a mission to help.

No matter how profitable apps are, they must not deviate from making this world a better place for all of us. However, more significantly, this is a “cliche” to some developers, but not for Dong Nguyen, the genius behind Flappy Bird.

Flappy Bird is one of those simple apps that made millions after its launching in May 2013. For one dollar to download, it was making $50,000 a day.

But Dong Nguyen was not just any developer turned entrepreneur. He’s someone who believes in more significant things. This character of Nguyen made him shut down Flappy bird in February 2014, despite the application’s high revenue of $320 million. This decision came when he saw how Flappy Bird was affecting so many people that got so much addicted to the game, with him also absorbing the stress.

“Flappy Bird was designed to play in a few minutes when you are relaxed,” Nguyen told Forbes reporter Lan Anh Nguyen. “But it happened to become an addictive product. I think it has become a problem. To solve that problem, it’s best to take down Flappy Bird. It’s gone forever.” (Dong Nguyen said in an interview with Forbes.)
