The secret to a great app? Great UX design. That’s why Flatlander Studio partners with founders and growing businesses: to bring high craft to custom mobile and web applications from concept to launch.

The Flatlander Studio difference

Why Kansas City Founders Partner With Flatlander Studio

Design-First Engineering

Code is important, but most apps win or lose based on the digital experience. Those micro-experiences benefit exponentially by design. We start with real user research and intuitive UX/UI design, so your app is easy to navigate from day one and built to hold onto the users you work so hard to acquire.

Direct Access, Not Layers

Lifecycle Launch Strategy

From feature scoping, rapid prototyping and testing to App Store Optimization (ASO) and post-launch iteration, we guide you through every stage of bringing a digital product to market.

InTimer youth sports fair playing time app  designed by Flatlander Studio in Kansas City

We Build
our own Apps, too

Flatlander Studio designed, built and manages InTimer, a field-first youth sports timing app used by coaches around the world.

Building InTimer required us to solve real problems:

• Challenges within high-distraction user environment
• Multi-language localization across 12 languages
• Ongoing iteration based on real coaches in their seasons

These and a dozen more nuances were accounted for in InTimer’s design and deployment–the same human-first approach we give to our client projects.

3

Architecture & Development

Clean, scalable front-end and back-end execution built to deliver fast load times, robust data handling and seamless platform performance.

4

Launch, ASO & Growth

We handle App Store & Google Play submission, metadata, visual assets and post-launch performance monitoring to help your app get found.


Frequently asked questions

Where is Flatlander Studio located?

We’re headquartered in Overland Park, Kansas, serving clients across the Greater Kansas City metro and delivering globally.

Do you work with startups or established businesses?

Both. We help startups turn a first idea into an investor-ready demo or a launch-ready app. For established businesses, we build custom mobile tools from the ground up or improve digital products that already exist.

What is the difference between custom app development and UX product design?

Product design is the research, user workflows, and interface work that makes an app intuitive to use. App development is the engineering that brings that design to life. We handle both under one roof, so nothing gets lost in the handoff between a design team and a dev team.

How much does it cost to build a custom app?

It depends on the platform, feature complexity and backend requirements. A super-simple MVP and a data-heavy, multi-platform app aren’t the same investment. Most of our engagements fall between $15,000 and $100K. On a discovery call, we’ll give you a real estimate based on your specific scope.
