Eric Spear

SVP of Engineering at Cengage

“Delivering high-quality code”
With NIX, I have broken some of my own rules of team composition with respect to the ratio of FTE and 3rd party engineers. I have some teams that are more than 50% NIX because the code coverage, quality, and velocity coming out from the NIX developers are very good. Delivering high quality code in a predictable manner has built trust and confidence with my management/full-time employees.

Craig Burris

“It is hard to impress me, and NIX kept me happy”
There is no recommendation that is more powerful. NIX’s expert team built a new system that increased potential customer traffic and improved performance. Their transparent workflow allowed for consistent communication and quick correction of problems when they arose. They also adjusted their processes to mitigate time-difference concerns.

Steve Berardelli

Sr. Director of Engineering for MindTap

“NIX is doing an amazing job”
NIX team contributed a lot to the process improvements for code deployment practices. So not only we write clean/stable code now but also, we are able to deploy it a lot more successfully and faster. We have a better strategy for our branch cutting and code repositories. It takes much less time to deploy code now with a higher level of stability. NIX team also contributed their ideas and views on how we can break up work among team members more effectively.

Mark DeJarnatt

Benefits of Custom Mobile App Development

Custom mobile apps are designed to satisfy tailored customer needs, create unique user experience, and implement exceptional design. They provide the highest performance, security, better resilience and scalability. With custom mobile app development you can realise uncommon business ideas, add new functions with each iteration, build complex apps to meet special consumers needs, address market challenges, and stand out from the competition.

Types of Mobile App Development

Typically there are 3 types of mobile application development:

  • Native
  • Cross-platform
  • Hybrid or PWA

Each approach was designed to tackle a specific business need with resource availability in mind. Basically they differentiate in terms of performance, time-to-market, and cost. Each type has its pros and cons that we’ll define and explain later.

Native App Development

Native application development is the process of building an app using a programming language native to the device and operating system.

  • Android native programming languages are Kotlin and Java.
  • iOS native programming languages are Swift and Objective-C.

This means that with native development you’ll always need to build two different versions of the app—one for Apple devices and another for Android. This results in the necessity to hire at least two engineers or teams to target each platform, which eventually increases the scope of work and cost. On the other hand, with native app development your app can achieve the best performance and resource efficiency. The biggest challenge for native app developers is to make the UI and UX look similar between the Android and iOS app versions while maintaining devices’ native appearance and features (buttons, navigation).

Cross-platform Mobile App Development

Cross-platform app development is the process of building an app using an intermediate programming language that is not native to the device’s operating system. Cross-platform apps are developed with React Native, Flutter, Xamarin, and others. With a cross-platform approach, a part or all of the code can be shared across targeted platforms—for instance, both iOS and Android. In some cases the app code could be reused even across web and desktop apps. Cross-platform apps usually incorporate some native programming code to resolve technical and visual discrepancies between operating systems, access some native device functions, or improve performance.

With cross-platform mobile app development only one team of mobile engineers is required for a project. Moreover, the time-to-market and app development cost could be decreased by almost double. The biggest challenge of cross-platform development is making the core code base holistic and scalable while keeping the amount of native OS-specific code injections as low as possible.

Hybrid Apps/PWA

Progressive web application (PWA) or HTML5 hybrid app development is the process of building mobile apps that draw UIs using a device’s web browser. Hybrid apps are types of cross-platform applications that leverage HTML, CSS and JavaScript. HTML5 hybrid apps are created with Cordova, Trigger.IO, Ionic, Telerik Platform, and others. They are limited in functionality, have low performance, poor design, and dependent on an internet connection. Hybrid apps could be developed very quickly, however they will lose in terms of user experience and scalability to other custom app technologies. PWA is a good choice for product tests and proof of business ideas in the early stages.

How to Choose the Right Technology for the Application

Choose what is more important to you: performance or cost. Native applications have the best performance and cross-platform approach is mostly cheaper. Choosing a particular programming language between decent alternatives is more about the access to qualified resources. You should go with the technology that will allow you to hire engineers easily and quickly. If you want to learn more—take a look at our special series of mobile technology comparisons: Flutter vs React Native.

Advantages of Outsourcing Mobile App Development

“Great things in business are never done by one person…” — Steve Jobs. There are a lot of big companies that have been taking advantage of engineering outsourcing, like Apple, Microsoft, Google, Amazon, Alibaba and many others. According to our customer survey, the most valuable benefits of outsourcing application development are:

  • Faster time-to-market
  • Reducing costs
  • Greater focus on core business
  • Solving capacity issues
  • Improving quality
  • Accessing the pool of talents and skills.

It’s not an easy thing to assemble a qualified app development team, provide them with interesting tasks, keep them motivated, and sustain professional growth. Outsourcing provides flexibility of engaging tailored engineering talents (like BA or data scientists) whom you are unlikely to offer a permanent position.

How to Choose Mobile App Development Company?

Gathering a dream engineering team is tough. The cost-first approach results in low-quality code, cutting corners on critical activities (like QA), and ultimately leading to the necessity to rewrite the application from scratch with a different team.

More than a half of our clients return when considering a new software product and recommend NIX to their networks. We believe that recommendations of colleagues and friends is the shortest way to find a reliable app development company.

Nevertheless, do not trust only words; dig deeper until you become confident about your decision. To improve the likelihood of successful collaboration consider researching the following areas:

  • Portfolios and examples of previous works
  • Client reviews and feedback
  • Overall impression about teams and communication

Consumers prefer mobile experience

Customers want to be smart buyers and get transparency and control from the devices in their pockets—not only within opening hours, but every time they feel the need, instantly and easily.

  • The smartphone owner on average unlocks her smartphone 150 times a day (Kleiner Perkins)
  • The average US adult spends 4 hours a day on mobile internet, and 88% of that time within apps (eMarketer)
  • Texts are read right away: 90% of texts are read within 3 minutes of receiving (Mobile Coach)

Mobile apps market and revenue are growing

The penetration of mobile devices is increasing as well as the amount of installed apps and daily active users. The competition between apps for users’ attention is getting tougher.

  • There were 3.5 billion smartphone users globally in 2020, which is expected to grow by 3.8 bn by the end of 2021
  • There were more than 2.87 million apps available in Google Play, and 1.96 billion in Apple’s App Store in 2020
  • Mobile apps generated $582 bn in revenue in 2020 and are projected to hit $1 trillion by 2023

FAQ on Custom Mobile Application Development

  • 01 What is custom mobile app development?

    Custom application development is the process of designing, engineering and releasing a unique app for mobile devices in accordance with specific business, technical and design requirements. Unlike off-the-shelf solutions, custom apps are built to satisfy a specific customer’s need in a particular way.

  • 02 Is custom app development worth it?

    In the most scenarios custom mobile apps are absolutely worth it. In very rare cases when you need a typical app, with a simple functionality for a short period of time (one month max) you should look for a white-label solution or consider not building an app at all.

  • 03 Could a mobile-friendly website substitute an app?

    No. Average US adults spend only 12% of their mobile internet time using a browser, and the rest of the time within apps. Moreover, applications allow users to be in the client’s pocket permanently, improve retention, decrease ad budget for re-acquisition, and take analytics to the next level.

  • 04 How long does it take to develop a custom mobile app?

    The fair answer is: it depends on requirements and resources available. According to BusinessOfApps, on average it takes:
    – 1-3 months for MVP with basic functionality, simple design and a back-end;
    – 4-8 months for mandatory functions, API integrations, advanced UX/UI, and server performance;
    -9+ months for additional functionality and special features.

  • 05 How much does it cost to build a custom mobile app?

    The fair answer is: it depends on requirements, project hourly estimation and developers rate.
    According to Clutch:
    – App MVP could be from $15,000 to $50,000;
    – A meaningful app is between $100,000 and $500,000.
