We’ve cut our teeth in a wide range of industries and verticals, but in all of our projects, we place a focus on making informed decisions and grounding the development process in real business outcomes. This means that our mission isn’t just to blindly build an application: we want to get a deep understanding of your business model so we can tie every decision to your overarching business goals and strategy. This allows us to create applications designed – at every level – to generate real ROI and growth for your business.

In keeping with this mindset, our app development philosophy and process is firmly rooted in an Agile framework. Agile app development is a framework for developing software that focuses on creating working, functional programs instead of a comprehensive plan – in other words, build first, test, and iterate. The principles of Agile are outlined in the Agile Manifesto:

  • Individuals and interactions over processes and tools
  • Working software over comprehensive documentation
  • Customer collaboration over contract negotiation
  • Responding to change over following a plan

We rely on Agile app development because, time and time again, it works. Agile is a flexible methodology that allows us to respond to new information and keep the app development process flexible, yet efficient. Whether you’re a scrappy, two-person startup or an enterprise corporation looking to test new product ideas, we provide app development that’s flexible, ROI-minded, and ready to grow and change with your business. That’s a recipe for success no matter what your app idea.

Mobile App Development for iOS in NYC


Why iOS?


iPhone app development is a no-brainer. Apple’s iPhone dominates some of the most lucrative markets in the mobile application world, and building an iOS app gives you direct access to these consumers. While the Android app market is larger in size, iPhones reign supreme in some of the most developed geographic markets like the US, greater North America, and Europe.

This bears out in the data. In aggregate, iOS apps make more money than Android apps: the App Store generated $34 billion in revenue in 2016, compared to just $10 billion on the Google Play store. The difference is even more stark when you consider app downloads: in the same year, the App Store saw 29 billion downloads, compared to the Google Play’s 63 billion downloads. That means, pound for pound, downloads for iPhone apps are statistically worth more than Android app downloads – so mobile app development for iOS may be the most lucrative option.

That said, iPhone app development has its drawbacks. Chiefly, iPhone apps must be approved by Apple before they can be listed in the App Store, and this process can as long as two weeks. This means iOS app development is a slower process when it comes to pushing changes and iterations, which may hamper mobile apps in their early stages. We’ve found user acquisition to be more expensive for iOS apps as well, which makes the mobile app design phase all the more important: the better your app can satisfy its user, the easier it will be to grow the user base.

Naturally, however, this all depends on the specifics of your app idea. The design of your mobile app, its key features, and its core user all matter when deciding whether to go with iOS app development or Android app development. Thankfully, as a leading mobile app developer serving the NYC market, we’re more than qualified to help you make that choice – and if you decide to launch on both stores, we’re experts in both programming languages.

Mobile App Development for Android in NYC


All of that said, Android app development is still a booming business. We’ve had great success as Android app developers, and we’ve even learned a few tricks specific to Android and the Google Play store to help us make Android apps successful.


As we mentioned, Android apps generate less aggregate revenue (for now), but they still dominate on downloads, generating more than twice as many downloads as the App Store in 2016. That trend is set to continue, as App Annie forecasts downloads from the Google Play store will grow to 129 billion downloads in 2021.

Why is that? It’s all about geography. The App Store is dominant in developed countries like the US, but these markets are farther along in maturation. This means that while they generate more revenue right now, they will not grow as fast as developing markets – if most people in the US own a smartphone (77% in 2017), then there are fewer people to buy smartphones in the future – which means less room for app downloads to grow. After all, how many people do you know who own in iPhone in NYC?

In contrast, the Android apps dominate in less developed countries and emerging markets like China and Latin America. While these markets aren’t as lucrative right now – again, lower smartphone adoption – they have much more room to grow. As they mature, we can expect revenue for Android apps to increase.

In addition to future growth, Android app development comes with a lot of benefits in the present. User acquisition cost is lower for Android apps, which makes it easier to test ideas and grow the user base for early-stage apps.

Furthermore, we can push changes to the Google Play store in just 2 hours, vs. several days on the App store. This means it’s very easy to publish a version of an Android app, gather data from users, then publish the next iteration quickly. Android apps make iterative, agile development much easier than iPhone apps, which sets you up for success in the long-term.
