We're ClimbNxt, and we've been creating mobile apps in Hong Kong since 2019. No fancy promises or buzzwords — just solid development that helps businesses connect with their customers through well-built iOS and Android applications.
Back in 2019, Hong Kong's mobile app scene was crowded with agencies making big promises and delivering generic solutions. We saw businesses struggling with apps that looked nice in demos but fell apart when real users started tapping around.
That's when Kai Bjornsen decided to do things differently. Instead of chasing every trend or promising revolutionary outcomes, we focused on one thing: building apps that work reliably for actual users. It sounds simple, but you'd be surprised how often this gets overlooked.
Six years later, we're still here because we've learned that businesses don't need the flashiest app — they need one that serves their customers well and doesn't break their budget or timeline.
We test apps on actual devices with real network conditions. That means your app works whether someone's on MTR wifi or dealing with spotty connections in older buildings around Central.
If something's going to take longer than expected, we tell you. If a feature won't work the way you imagined, we explain why and suggest alternatives that will actually function properly.
We build apps with maintenance in mind. When iOS 19 comes out or Android updates their requirements, your app won't suddenly stop working because we cut corners on the foundation.
Small team, focused approach. We prefer working closely with clients rather than managing dozens of projects at once. This way, your app gets the attention it deserves.
Kai handles the core development work — from database design to API integration. He's been writing code since university and has seen enough failed projects to know what causes apps to break down after launch.
Every project starts with understanding what you're trying to accomplish. Not just the features you want, but the business problem you're solving. This helps us build something that actually serves your users.
Working in Hong Kong since 2019 means we understand local user expectations, payment preferences, and the unique challenges of serving both English and Chinese-speaking audiences effectively.
Here's how we typically work with clients, from initial conversation to app store launch. Each project is different, but this gives you an idea of what to expect.
We spend time understanding your business needs and user requirements. This isn't just about features — it's about figuring out what success looks like for your specific situation.
We build your app using proven frameworks and test it thoroughly on multiple devices. Regular check-ins keep you updated on progress and let us adjust course if needed.
We handle app store submissions and provide ongoing maintenance. When issues come up or you need updates, we're available to help keep your app running smoothly.
