Agile Mobile App Dev Company LA

Whether your company’s project is big or small, user-facing or B2B, startup or enterprise, Rootstrap scales to your needs.

At Rootstrap, we firmly believe in Agile development. Agile is a software development methodology that prioritizes building functional software above all else. 

Instead of spending excessive time in the planning stages, we work to create a lean minimum viable product (MVP) and get it in front of users as soon as possible.

Here are the four main principles of the Manifesto for Agile Software Development:

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

Getting a functional product in front of users helps us earn from the people we want to reach with your app. Gathering valuable feedback from your audience during the early stages of development lets us ground every succeeding decision in what real users want.

Our Product Development Process & Deliverables

As soon as we have the green light we can get a project up and running in less than two weeks. 12.4 days to be exact. Led by our Discovery Process, here's how we work:

Mobile App Designers in Los Angeles

Rootstrap - Mobile App Icon

Of course, development is impossible without design – and mobile app design is one of our core service offerings at Rootstrap. In fact, this is so important to us that we have a standalone process dedicated purely to mobile app design: Discovery

Discovery is the seed from which our greatest projects have grown as it creates a shared map to exactly where you want to be. It's a pre-development process that helps us answer the biggest questions before putting down big money for development: 

Discovery helps us answer the following questions:

  • Who will use this app?
  • Why do they need it? 
  • Why is it better than what’s already out there? 

Discovery serves to define your concept, validate it in the marketplace, and map the course to launching the final product. 

Trust the Discovery Process

We break the Discovery process into 4 key phases

Setting the Vision

Through our honed Discovery process, we work with you to unearth the unique value proposition your project represents. Having a shared, crystal clear understanding of the mission is essential to avoiding feature-creep and unnecessary distractions.

Accurate Estimates

Asking how much it costs to build an app is like asking how long is a piece of string. It depends on a wide array of variables and unknown unknowns. Discovery helps us co-create a shared understanding of what it will take to

build and release an MVP.

Design/Code Assessment

Design/Code Assessment

If you’ve already started down the path of building your product but are finding your current resources lacking, we will take a look at the existing work to see what can be used, what can be improved, and what needs to go. 

Defining the Goal

By understanding your vision, assessing any existing assets, and co-creating a plan for the core functionality needed for an initial release, we can shave weeks or months off the project timeline - and the budget.

Mobile App Development for iOS in Los Angeles

The Apple App Store is a lucrative marketplace many startups are eager to join.

“In 2020, customers spent an estimated 72.3 billion U.S. dollars on...in-app purchases, subscriptions, and premium apps in the Apple App Store,” reports Statista.

Still, this massive marketplace does not guarantee a product will meet with success. Creating an app that’s worth downloading starts with enlisting a good team.

The Rootstrap dev team has been building world-class iOS apps for years. Our software engineers are masters in iOS development. How do we do it?

We’re militant about the code standards for our iOS apps. We’re equally at home in Swift, C, C++, Objective-C, or any other language you prefer. Beyond that, our commitment to Agile means we work hard to make sure we’re building as lean and efficient as possible.

Pro tip: Our experience equips us with insight into what it takes to get apps featured in the App Store. We’ll work with you to give your product the best chance possible.

Still, all the world’s technical proficiency is nothing if you don’t reach a positive ROI. From inception to design to development, we base every decision on users’ needs and your company’s long-term goals. That way, we can help you tap into the juicy Apple market and get a strong ROI.

Mobile App Development for Android in Los Angeles

iPhone apps may get more of the spotlight, but companies should not overlook Android app development’s growing value.

“In 2020, Google Play users worldwide downloaded 108.5 billion mobile apps, up from 76 billion apps in 2018,” says Statista. “Google Play generates significant[ly] more downloads than the Apple App Store, as it is available for a wider range of devices than Apple's closed iOS ecosystem, which is only available for Apple devices.”

On another level, Android is a more flexible platform than iOS in several key ways. User acquisition costs less for Android apps than iPhone apps, which means it’s cheaper and easier to build a user base for an Android app than on iOS.

Additionally, Google Play allows you to publish updates faster than on the Apple Store. This flexibility makes iterative development easier and more efficient. Google Play will enable us to publish an initial v1.0 on Android, gather data from users, and iterate the app in real-time.

We always recommend releasing an app for both Google Play and the Apple App Store. However, if money is tight, we’ve seen success by building an initial user base on Android, then launching on iOS once your app gains traction and has a stronger market position.

If you’re stuck debating between launching an Android or iOS app or both, don’t stress it too much. Ultimately, there’s no right answer. How you choose to allocate development resources and bring your mobile app to market all depends on the specifics of your app concept, your key value proposition, and your target user demographic.

When you work with Rootstrap, we help you answer all these questions before building the app.

How much does an app cost?

An app development agency’s location and its development methodology approach also contribute to the final cost.

See how companies are using IT staff augmentation as an alternative to help lower app development costs.

Is it better to have my app developed in Los Angeles or San Francisco? 

San Francisco is an undisputed hub of app development due to its proximity to Silicon Valley and VC funding. Similarly, the Los Angeles tech scene (Silicon Beach) is now home to tech industry leaders such as Hulu and Google.

While San Francisco has a deeper talent pool, Los Angeles app developers continue to flourish due to its industries’ diversity and access to LAX. Financially, the two cities have hourly rates ranging from $100 - $199.
