Great Experience With HoangKim on Our Mobile App Development Project

Mark Reed / Managing Director | Oct 13, 2026

We were very happy with how this project went. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

It has made a real difference to how our team works day to day. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with HoangKim to build iOS and Android apps for our customers, including booking, payments and push notifications. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 9 months from kickoff to launch.

HoangKim Delivered a Quality Mobile App Development Solution on Time

Sophie Barker / General Manager | Jul 20, 2026

HoangKim did good work for us, and we would use them again. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Overall, a team we trust and plan to keep working with.

Professional Web Development Team, Smooth Delivery From Start to Finish

Daan Jansen / Head of Engineering | Jul 17, 2026

HoangKim did good work for us, and we would use them again. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Feedback from our customers has been very positive so far. There were some early misunderstandings on requirements that took a few rounds to sort out.

Happy to recommend them.

Good value and a team that genuinely cares about the result

Heather Patel / Director | Jul 10, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The result looks great and performs well, and our internal team found it easy to take over.
