What is Mobile App Development?
Mobile development is building software to run on mobile devices like tablets, smartphones, and smartwatches. Everything from Instagram to enterprise apps fit in this category. Mobile apps are built for the general public, private companies, and the government. Mobile apps might be native (written in a specific platform’s language) or non-native, written to work on multiple platforms. Android apps are typically written in Java while Apple/iOS apps are written in Swift or Objective-C. These languages are preapproved by the vendor who manufactures the device.
How to Become a Mobile App Developer
You could get a degree in computer science and then teach yourself Swift, Objective-C, or Java online. This option will take ~4 years and cost over $100,000. While Android and iOS aren’t the only platforms out there, they do comprise 99% of the market.
Mobile Developer Bootcamp
Learning to code with a bootcamp is probably the fastest option. If you learn better in a classroom, need career assistance, or want the connection of a cohort to bolster your learning experience, then bootcamp is for you! Most bootcamps specialize in either iOS or Android. Mobile bootcamps can range from 5 weeks to 10 months, and vary in price from $5,000-$15,000. Tuition range depends on a variety of factors based on location, immersive vs part-time, online vs in-person. Many bootcamps now offer deferred tuition, Income Share Agreements, and financing options.
Online Learning Resources
Of course, you can learn the technical skills to become a Mobile App Developer entirely online. This option is for the self-starter who is disciplined and creative enough to build their own curriculum or pay for an online, self-paced curriculum. Online resources like Team Treehouse and Codecademy offer free trials and paid monthly subscription.
How to Choose a Mobile App Development Bootcamp
The best mobile app development course for you depends on your own learning style, career goals, availability, etc. Here's our advice for choosing the best app developer bootcamp:
-
Narrow down your options – you can rule out some bootcamps based on location, cost, and time commitment.
-
Examine the curriculum – does the bootcamp teach the most modern mobile app developer tools like Swift and Unity? On top of those new languages, you should also be learning fundamentals like Java and iOS.
-
Ask About Projects – in the world of mobile app development, your portfolio is important! At a good mobile bootcamp, you'll build at least 2-3 projects to add to your portfolio!
-
Meet the Instructors – do the bootcamp instructors have real-world design experience? Have they worked for mobile app agencies or built their own apps? Pro-Tip: Take an intro course or free workshop hosted by the bootcamp to really understand the teaching style.
-
Ask About Outcomes – do past bootcamp graduates get jobs in mobile app development? Ask the school directly for their CIRR report or job outcomes report, read bootcamp reviews, and even reach out to alumni on LinkedIn to ask questions.
Red Flags – instructors don't have experience building specifically for mobile, the school can't tell you about past student career success, or the bootcamp only teaches no-code tools instead of training you in the underlying programming languages.
Mobile App Developer Jobs
Mobile app developers are in high demand regardless of which platform you choose to build for. The mobile app economy is expected to hit $102.5 billion in revenues in 2020. There have never been more mobile devices on the market as there are right now. After a mobile development bootcamp, you can design native apps for a vendor like Apple or Google, develop apps at a startup, or even create your own app and start a business yourself!

Android vs iOS Mobile App Development
The demand for Android and iOS Developers are about the same, with about 5,000 open jobs each in the US on average. The pay for Developers on both platforms is almost equal as well. In the US market, iOS controls about 58% while Android makes up about 41%. Globally, however, Android takes over 73% of market shares while iOS rings in at just 26%.
Aditya Narayan, the CEO and co-founder of TurnToTech says, “Because there is so much opportunity in mobile right now, it’s completely legitimate to go with what you like to use as a user. But you can be more analytical than that. If your aspirations are tied to the international market, Android is a good option. If your focus is the US market or you want to monetize through in-app purchases, iOS is your best choice. It’s not a once in a lifetime decision. If you can write apps in iOS, you can easily transition to Android and vice versa.”
How to choose between Android vs. iOS: If you’re starting as a complete beginner, then Android and iOS will likely take the same amount of time to learn. If you’ve already learned Java, start with Android. If you’ve already learned C++ or C, pick up iOS first.
