Rootstrap - Mobile App Icon

Our focus is on creating apps that generate real ROI. We’ve worked in a wide range of verticals and industries, but in everything we do, we strive to tie every element of the mobile app design and development process to overarching business objectives. We don’t want to just blindly build you a product: we strive to get a comprehensive understanding of your business model, your industry, and where your business is going. We want to understand how mobile app development fits into the overall goals of your organization – because that’s what lets us create a mobile app that truly moves you forward.

At Rootstrap, we firmly believe in Agile development. Agile is a software development methodology rooted in building functional software above all else: instead of spending too much time planning and suffering analysis paralysis, we work to create a lean MVP and get it in front of users as soon as possible. The core tenets of Agile are laid out in the Agile Manifesto, which informs every aspect our business:

  • 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 use Agile development because it works. Getting a working product in front of users lets us get out of our heads and learn from the people we want to reach with the mobile app – and doing it early in the process lets us ground every decision in what real users want.

Whether it’s a simple Android MVP, a massive enterprise iOS app, or some crazy new technology we haven’t even thought of yet, Agile development lets us build functional, beautiful products that generate real ROI for our clients. Don’t believe us?

Mobile App Design in Los Angeles

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 product dedicated purely to mobile app design: Roadmapping. 

Roadmapping is the seed from which our greatest projects have grown. It’s a standalone pre-development product workshop that answers the biggest questions before putting down the big money for development: who is this for? Why do they need it? Why is it better than what’s already out there? Roadmapping serves to define your concept, validate it in the marketplace, and build a detailed roadmap to developing the finished product. 

Rootstrap - Mobile App Icon

We break the Roadmapping process into 4 key phases

Trust the Process


First things first – we have to understand what we’re building. In the initial phase, we work to completely define your app concept. Not just what it does, but how it helps its users –the key value proposition it provides.


With the concept in place, we move into sketching. In this phase, our goal is to explore every possible solution and architecture we can think of. No idea is too obvious or too anodyne – it’s all about moving through the solutions and features that won’t work so we can get to the one that works the best.

Now it’s time to bring the baby to life. With a detailed understanding of the concept and core value proposition in place, your app design team will craft a comprehensive, high-fidelity clickable prototype of your product. 

Refine & Prep

Finally, we’ll get you ready for development. Drawing on the work done in the previous three phases, your team will work with you to create a detailed product backlog: a comprehensive document that outlines every feature and functionality of the mobile app. We’ll then help you groom and prioritize this backlog, outlining exactly what you need to build for v1.0 and all subsequent builds of the product.

Mobile App Development for iOS in Los Angeles

So you want to build an iPhone app?

Good on you. iPhone apps offer a juicy market, and we’ve been building world-class iOS apps for years. Apple’s App Store generated nearly $40 billion of revenue from 28 billion downloads in 2017, and if the trend holds, those numbers will get even larger in the coming years.

Rootstrap - Mobile App Roadmapping

But a big market does not guarantee a successful product. If you want to build a successful mobile app, you need a good team.

We’ve got you covered. Our engineers are masters in iOS development, and 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 want to work in, and our commitment to Agile means we work hard to make sure we’re building as lean and efficient as possible. We’ve also learned a thing or two about what gets apps featured in the App Store – and we’ll work with you to give your product the best chance possible.

But beyond technical proficiency, our entire process is built to help you reach positive ROI. From inception to design to development, we ground every decision in the needs of users and the objectives of your larger business. That $40 billion market is tempting, but you have to know what you’re doing to get a piece. That’s what we’re here for.

Mobile App Development for Android in Los Angeles

iPhone apps may get more glitz and glamour, but there’s a lot to be said for Android app development. 

For starters, Android apps get more downloads than iOS apps on the whole. The Google Play store generated 64 billion downloads worldwide in 2017, more than twice that of the App Store. And while it’s nowhere near App Store revenue, the $20 billion of revenue that Google Play garnered in 2017 is nothing to shake a stick at.

Rootstrap - Mobile App Staff Augmentation

On another level, Android is a more flexible platform than iOS in a number of important 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. Furthermore, Google Play allows you to publish updates in just 2 hours – much shorter than the App Store’s waiting period, which ranges from a few days to two weeks.

This flexibility makes iterative development easier and faster: it allows us to publish an initial v1.0 on Android, gather data from users, and iterate the app in real time. We always recommend releasing on both platforms, but if money is tight, we’ve seen success by building an initial user base on Android, then launching on iOS once there’s a stronger market position.

But ultimately, there’s no right answer here. 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.

The good thing is that when you work with Rootstrap, we help you answer all these questions before we start building the app.

Frequently Asked Questions

What questions do I ask an app developer?

How much does an app cost?

Los Angeles vs San Francisco for app development

San Francisco is an epicenter for 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 the diversity of its industries and access to LAX. Financially, the two cities have hourly rates ranging from $100 - $199. You can contact us to learn more about app development in Los Angeles.

Rootstrap - Mobile App Growth User Acquisition

The development costs of an app can range anywhere from $80k to $250k+, depending on the complexity and scope of the app, as well as its intended platform and category. An app development agency’s location and their development methodology approach are also contributing factors. See how companies are using IT staff augmentation as an alternative to lower costs.

When shopping around for an app developer in Los Angeles, the three most important factors to ask about are development methodology (agile vs waterfall), strategic planning, and market validation. A track record of past work and a return on investments are also important factors to take into consideration. You can contact Rootstrap with these types of questions for a quote.
