The 5 Best Mobile App Developers in Hong Kong You’ll Love Working With
The thing with Hong Kong businesses is that everyone wants an app to take their services and products to new heights. But hiring a mobile app developer? That’s a whole different story.
When we first started searching for firms, we didn’t expect to see so many companies that claim they’re the “next big thing.” We can’t just take their word for it – we had to put them to the test to see which options are really worth the shot.
By reviewing multiple portfolios and interviewing one business owner after another, we managed to find the best app developers in Hong Kong. A few work best with startups – others are more equipped for complex builds.
See them all here!
How much does mobile app development cost in Hong Kong? The cost of mobile app development in Hong Kong starts at $60,000 for simple, general-purpose apps. Hybrid apps can cost anywhere from $150,000 to $300,000. Native apps (iOS/Android) range from $200,000 to $800,000. |

UXlicious earned our trust with their comprehensive development process. They cover every stage from the user research and wireframing to testing and post-launch improvements.
Clients told us that they often work directly with the senior designers, which is not always common in Hong Kong agencies.
We find this level of collaboration to be crucial in complex projects, such as e-commerce platforms, productivity apps, and large-scale financial tools.
Beyond the process, the results are just as impressive. As we’ve reviewed their portfolio, we found that they helped clients improve conversion rates, sign-ups, and retention. One client even went from 3.8-star ratings to 4.5 after a redesign.
The team adapts to each company’s needs, showing great flexibility in various projects. Based on case studies, they’re able to develop solutions from simple hotel websites to complicated dashboards for task management.
If there’s a downside, it’s that the company often sends unsolicited mass marketing emails. It doesn’t affect the quality of their work, but we know how that can affect the overall communication process.
Knows what they’re doing
“Big thanks to UXlicious for their excellent UX design work. They helped redesign my online store for selling art pieces, and I saw a clear improvement in conversion rate after the changes. The site feels smoother, more user-friendly, and way more professional. The team really knows what they’re doing and pays attention to the little details that make a big difference. Highly recommended.”

Outcome was beyond expected
“We worked with UXlicious on our AI app, and the outcome was way beyond just nice design. Their UX/UI design ideas actually helped improve our conversion rate, sign up rate, and even user retention. Both our product and marketing team learned a lot from them, especially when it comes to setting the right metrics to track. They really pushed us to think deeper about what matters to users, not only what looks good. Truly recommend this agency.”

GreyLoud’s track record is impressive, considering they have over 1 million development hours completed. They also offer a wide range of services that make them a full-rounded app agency.
They have business analysts, project managers, designers, and testers in the team. This makes them a one-stop solution, especially for enterprise solutions, UX and UI design, and overall digital transformation.
We liked that they specialize in low-code development, which allows them to deliver apps 5 times faster at 80% less cost. Considering this, we find them a solid choice for startups or businesses on a tight budget.
Another strength is their consultation process. The company offers free initial consultations and maintains realistic expectations. The turnaround is anywhere from 3 to 6 months, depending on the complexity of the project and business goals.
If there’s one limitation, it’s that their methodology is less suited for projects requiring complex algorithms or heavy animation, like gaming apps. But for reliable, fast, affordable apps, they can be anyone’s trusted partners.
Goes above and beyond
“GreyLoud has been a valuable partner in our success for more than 3 years. It’s clear they care about their customers, as they have gone above and beyond our expectations. When selecting GreyLoud, it was very important for us to be confident our project will arrive at the correct result. The strength of their technical talent has continuously delivered and given us the confidence we were looking for !”

Established in 2010, iExcel has over a decade of experience building enterprise-grade solutions that deliver measurable business impact. Their services cover the full spectrum, from custom app development to software testing.
On top of these offerings, they also offer consultations in data analytics, digital strategy, and business performance. We find them to be a robust firm for complete app makeovers, especially if there are specific business goals in mind.
In mobile apps, their portfolio is strong. The team builds across platforms like iOS, Android, React Native, Flutter, and HTML5. We also like that they integrate advanced technologies like AI, IoT, blockchain, and AR/VR.
With these solutions, they’re able to prioritize usability, speed, and security in their apps. In particular, clients praise them for their scalable and stable apps that make it easy for businesses to expand their offerings without delays.
For small businesses, their entire service catalog may feel overwhelming, as simple and small apps aren’t usually their niche. But for those with large-scale needs and ambitious app goals, they’re the perfect partner for the mission.
Friendly and professional.

Rovertech is among HK’s most reliable app and web development companies. We liked their breadth of services. Beyond mobile apps, they also provide system development, AI-powered solutions, and more.
What impressed us most was their ability to work with both startups on limited budgets and large enterprises requiring advanced features.
In general, the team prioritizes smooth navigation and intuitive layouts – something that clients said helped them achieve higher conversion rates and stronger user retention.
On top of that, they’re able to include features that make apps more reliable for the average user. For example, they can implement membership systems, discount engines, and inventory tracking.
Customer support is a win as well, as they’re responsive to any app issues. In fact, many businesses find them to be a reliable long-term partner.
Pricing is another positive. Rovertech offers affordable entry-level packages for startups. They’re not the cheapest on this list, but the fees are competitive. And considering the level of collaboration, every penny feels worth it.
The only improvements we wish to see are with their timeliness – we did meet clients who said their target schedules were extended due to delays. However, this seems to be an isolated case with a heavily complex build.
Exceptional app development services
“Working with Rovertech on our web and AI development projects has been fantastic. Their AI system meets our clients’ needs instantly and has improved our operations efficiently. I highly recommend them for exceptional web and AI development services!”

Fora Soft offers services in video streaming and real-time software development – one of the very few firms in HK that offers these. They have a 100% project success rating, having completed 625 projects as of this writing.
The level of specialization extends to AR/VR applications and AI-powered developments. This makes them a solid choice for industry-specific solutions such as telemedicine, video surveillance, and e-learning.
For startups, we like that they offer free 20-hour planning sessions. Other companies can also benefit from their 2-week trials and free code audits. This allows businesses to test their expertise before committing to long-term collaboration.
Clients we interviewed praised their planning process. From custom architecture plans to interactive wireframes, the firm reduces guesswork in every stage.
Thanks to clear documentation, scalable architecture, and proactive quotes, apps are launched earlier than expected.
The biggest drawback, though, is their exclusivity to multi-media and real-time projects. Simply put, they’re not the most versatile option for all needs. For specific industries (like telemedicine), they’re a standout option.
Innovative services
“Expert and efficient team and super professional and innovative service. Would highly recommend and work with again on the next high end development project.”
