Mobile App Development in Denver

Trusted by Fortune 500’s and Public Companies

Any app developer can build an app. At Rootstrap, we believe in doing more. 

Our mission is to enact a new vision for mobile app development. Instead of just building to spec and pushing out something pretty, we believe in ROI-focused development. From the start of the app design and development process, our mission is to understand how a mobile app fits into your business and serves your larger objectives. We make every design and development decision with your overall business and target market in mind – because that’s how you build mobile apps that win over real users. 

Our focus is to derisk your investment and deliver you a product that users will actually engage with. We've developed 250+ products for 500 founders with a combined revenue of 100m+. We battle-test every idea that we work on to make sure it can stand the test of time throughout market shifts and rends.

Rootstrap has been developing world-class mobile apps for nearly a decade, and in that time, we’ve taken on just about every kind of mobile app development project under the sun. We’ve built lean, single-function MVPs, hulking enterprise mobile apps, experimental AR and VR installations, and everything in between. Our client list features the likes of Tony Robbins, Snoop Dogg, and Epson.

Before development, though, we need to focus on mobile app design – and that’s one of our specialties. In fact, we have a proprietary model for mobile app design called Roadmapping.

Roadmapping is Rootstrap’s flagship service offering. Roadmapping is largely how we made a name for ourselves, and it continues to lie at the core of our business philosophy. 

Roadmapping is a 2-4 week pre-development product workshop. It’s a small, low-risk engagement that aims to answer the big questions about your mobile app before we start development: who is this for? What benefit does it provide to users? How will it fare in the existing market? Roadmapping is a way to de-risk your investment: we aim to answer the question of if the app is worth building before we start writing code.

We break the Roadmapping process into 4 key phases

Define

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.

Sketch

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.

Prototype

When you choose a mobile app development company for your project, you have to trust that organization. Choosing an app developer isn’t like buying from a vendor: you’re choosing someone that will help define the core of your product. You need to trust that team. 

Thankfully, ours is world-class. At Rootstrap, we have a team of nearly 100 people, including more than 60 full-stack engineers. Our company is home to UI designers, UX architects, business strategists, growth hackers, and product geniuses all dedicated to the success of our clients. We’re capable of serving enterprise-level organizations so we can grow as you do, and our distributed, global team means we can work when you do – and even when you’re off for the night.

Now, the immortal question:

Should I make Android or iOS apps?

We’d recommend developing for both the Android and iOS platform – but sometimes, resources force you to prioritize one over the other. There are great arguments for both, and ultimately it depends on the specifics of your mobile app. So why would you build an iOS app?

Looking purely at the numbers, iOS apps generate more global revenue than Android apps. The App Store generated roughly $40 billion in revenue in 2017, double the Google Play store’s $20 billion. It’s also significant that the App Store saw only 28 billion downloads, while Google Play saw 64 billion. This means, effectively, that the App Store generated twice as much revenue with half as many downloads. Pound for pound, iOS app downloads are worth more. 

Apple isn’t everything, though. Android app development is still a worthwhile pursuit that comes with its own list of unique benefits. 

For one, the Google Play store is much more flexible for app developers. Google Play allows changes and updates to go live in just 2 hours, which means we can improve the app based on user feedback in real time. For new startups trying to perfect their mobile app, this is a big advantage. User acquisition cost is also lower on Android, which means it’s faster and cheaper to iterate your product and build a user base.

Ultimately, though, there are no right answers here. The best platform to use depends – just like everything else – on the specifics of your app concept, target market, and business objectives. That’s why we make it our business to be experts in all of these fields, giving you a comprehensive partner in both the strategy, design, and development of your app. 

So drop us a line. We’re always happy to hear from potential new clients, and we take all comers – you don’t need a fleshed-out plan. Even some of the biggest companies in the world started as chicken scratch on the back of an envelope. 

Give us a call. We’ll set up a time to talk about your idea and see if there’s a mutual fit for building the product. 

Let’s build something great together.
