Top 5 Mobile App Development Technologies for startups in 2021

Updated on Jan 12th, 2024


It is no longer an option to get a Smartphone, but it has become a requirement in today’s era. Mobile phones have become an indistinguishable component in our everyday lives. It starts with Waking up with an alarm, checking messages, listening to music, watching videos, playing games, reviewing emails, updating status, and many more. It all runs smoothly from mobile applications on our mobile phones. If we speak about the Smartphone industry, almost one decade has gone by. The use of mobile applications is growing after each passing day. As per the reports, application downloads are expected to rise to 352 billion by the year 2021, though we can note the never-ending rivalry with this tremendous increase in mobile applications development. There’ll be about 7 billion mobile users in the year 2021, as well as an aggregate of 90% of the time is assumed to be spent on mobile applications.

Indeed, always remember that it’s not relatively as easy to achieve business success via a mobile application as coming out with the million-dollar idea of a mobile app. Consequently, as the number of applications being released in different app stores, competition often rises and makes it difficult for startups to thrive in the market. One of the critical reasons, other than experience, is Technology plays a crucial role that can turn an average application concept into a million-dollar accomplishment. Recognizing Technology could be a hit on is simple when it comes to an expert software development process, but it’s difficult for a startup to select the most suitable Technology. Don’t worry; we are making this task easier. Thus, In this blog, we’ll be looking at a few of the best technologies for startups to build mobile applications in the year 2021.

So without any further ado, let’s get started.

Why are Mobile Applications gaining so much Traction?

Reasons-Behind-Increasing-Demand-of-Mobile-App-DevelopmentAccording to a new study by Statista, in the second quarter of 2020, approximately 28 billion times applications were downloaded from Google Play, and over 9.1 million applications were downloaded from the Apple App Store. Through this stat, you will get a strong idea that the Play Store and App Store have countless mobile applications. A new mobile application is released every instant, which outdates the current ones and supersedes mobile apps’ development sector.

Well, still in doubt? Have a look at these market stats:

  • The reports predict that, on average, a user install 20-30 apps and spends over 3 hours a day on mobile apps.
  • As per the source, by the year 2022, the app store spending is predicted to rise by 92% to 157 billion dollars globally.
  • Over 87% of users check their phones in one hour.
  • On record, over 100K apps were launched every month on Google Play.

The application needs to offer something distinct and user-friendly to capture the user’s attention. Then and only then will you expect the users to download your application in the longer term and use it.

Well, here are a few best disruptive technologies for mobile applications that certainly ensure success for startups in 2021.

kotlin-mobile-app-developmentKotlin is a cross-platform, structured-typed programming language with a type interface that was first introduced in 2011. It’s completely interoperable with Java and JVM versions over its standard library centered on Java Class Library. The most major programming language for developing new mobile apps has indeed been Kotlin. For generating legendary mobile applications, Android app developers and startups select Kotlin as their favorite Technology. Using Kotlin, programmers only have to write a few code lines, which is more straightforward than some other programming languages. The reason behind immense popularity and why developers prefer more is that it’s secure, precise, and comprehensive support tools.

Why Kotlin?

App development using Kotlin provides improved and top-notch protection against all odds. Kotlin makes it possible for its developers to draft fewer code lines and have an excellent user experience, resulting in fewer bugs and errors. Kotlin seems to have no latency runtime and has a robust community that draws larger programmers to Kotlin.
