Rootstrap Product Development Process & Deliverables

When you come to us with an idea we don’t waste any time getting started. Once we kick off our Discovery Phase, we can get to work in as little as 12.4 days. Here's how we do it:

Our Discovery Process

Discovery creates a shared map to exactly where you want to be. With Discovery we can:

  • Set the vision for your project
  • Provide design & code assessments
  • Provide accurate project estimates
  • Define the goal of the project

Once underway, our app development philosophy and process are 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 as follows:

  • Responding to change & not just sticking to the plan
  • Collaboration with clients over negotiating contracts
  • Functioning software over comprehensive documentation
  • Interactions with individuals instead of processes and tools

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 fluid 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 dynamic, ROI-minded, and ready to grow and change with your business. That’s a recipe for success, no matter your app idea.

Mobile App Development for iOS in NYC

Why Create an iOS App?

Your headline

iPhone app development is the focal point of the industry. 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.

The Android app market is the largest in the world. Still, Apple products continue to reign supreme in some of the most developed geographic markets, including the United States, Canada, Japan, and Europe.

Every year, the global mobile app market for both iOS and Android sees massive growth. The fact that iOS apps furnish a more lucrative marketplace shows in preliminary app store data from 2020.

“Globally, consumer spending on the App Store reached $72.3 billion, up 30.3 percent Y/Y from $55.5 billion in 2019,” reports SensorTower. “As in previous years, this exceeded the amount users spent on Google Play, which grew 30 percent Y/Y from $29.7 billion in 2019 to $38.6 billion.”

Statistically, downloads for iPhone apps generate more revenue than Android app downloads making mobile app development for iOS a potentially more profitable 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 lag means iOS app development is slower when pushing changes and iterations, which may hamper mobile apps in their early stages.

We’ve also found user acquisition to be more expensive for iOS apps. This added cost makes the mobile app design phase all the more critical. The better your app can satisfy its user, the easier and less expensive it will be to grow your user base.

Choosing between the two platforms depends on the specifics of your app idea. The design of your mobile app, its key features, and its core user all play into the decision of going with iOS app development or Android app development.

Thankfully, as a leading mobile app developer serving the NYC market, we can provide professional insights to help you decide on the best market for your app. Whether you opt to launch on one store or both, we’re experts in iOS and Android programming languages.

Mobile App Development for Android in NYC

While iOS apps generate more revenue in mature markets, Android app development is still a booming business.

At Rootstrap, we’ve met with success as Android app developers. Along the way, we continually pick up on tips and tricks specific to Android and the Google Play store. These insights help us make profitable Android apps.

While Android apps currently generate less aggregate revenue than iOS, they still dominate on downloads, receiving more than twice as many downloads as the App Store in 2016. The Google Play store also has more available apps than the Apple App Store.

“As of the third quarter of 2020, Android users were able to choose between 2.87 million apps, making Google Play the app store with [the] biggest number of available apps,” says Statista. “The Apple App Store was the second-largest app store with almost 1.96 million available apps for iOS.”

Why is it that Google Play gets more downloads but generates less revenue? It’s all about geography. The App Store is dominant in developed countries like the US, where users are likely to have an iPhone and spend more money on apps.

In contrast, Android apps dominate in less developed countries and emerging markets like China and Latin America. While these markets aren’t as lucrative right now, 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 carries a few more perks. For example, the average user acquisition cost is lower for Android apps, making it easier to test ideas and grow the user base for early-stage apps.

Beyond that, developers can publish updates to the Google Play store in just 2 hours, a process that takes several days on the App Store. Google makes it easier to publish a version of an Android app, gather data from users, then publish the next iteration quickly. Speedy updates make iterative, agile development much more efficient and can set your app up for long-term success.

NYC Client Testimonial

ORI GOLDMANCo Founder at Loftey, NYC

"When I was looking to build my MVP I spoke to about 10 shops. Little did I know that I would be still working with the same company over 5 years later. Rootstrap built our MVP and we have stuck with them ever since. Through multiple pivots, design changes, thousands of implemented features, we still feel lucky that we found them 5 years ago".

Frequently Asked Questions

NYC vs San Francisco for app development

New York leads San Francisco as the number one 'tech city' for app development, with the latter coming in second. New York’s global image as the center of commerce, as well as its industry-leading tech residents and transport links, gives the city a slight edge over San Francisco with its deeper talent pool. San Francisco’s app developers remain in high demand, and financially the two tech cities are similarly high in cost when it comes to budgeting.

Is NYC expensive for app development?

New York City has one of the highest costs for app development in the United States. This is due to its deep talent pool and global image, as well as it now being home to tech industry leaders such as Apple, Facebook, and Google. The average hourly rate for a New York City app developer is $100-$150, with minimum project size requirements starting at $50,000. See how companies are using IT staff augmentation as an alternative to lower costs.

Do I need an NDA to share my idea with a dev?

When sharing ideas with a prospective app developer, a non-disclosure agreement is an effective way to ensure project objectives and information remain private and out of the public eye. This sense of security is beneficial when pitching ideas to app development agencies, especially if there isn’t a mutual understanding concerning app development between both parties.
