Solid delivery, though timelines needed some pushing

Hui Min Tan / Chief Digital Officer | Sep 17, 2026

The final product works well for us, although the process could have been smoother. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We launched on schedule and have not had any major issues since. We had to follow up a few times on smaller bug fixes after launch. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We engaged 21CN to develop a field-staff app with offline mode that syncs back to our main system. The work covered requirements, design, development, testing and launch support. Overall it was a 6-month engagement.

We needed to develop a field-staff app with offline mode that syncs back to our main system, and we didn't have the in-house capacity to do it ourselves.

End-to-end Mobile App Development — from requirements and design through to deployment and a support period afterwards.

Strong Technical Skills and a Very Responsive Software Development Team

Wei Jie Lim / Program Manager | Aug 04, 2026

We were very happy with how this project went. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

We launched on schedule and have not had any major issues since. If you need a team that communicates well and delivers, they are a good choice.

Great team to work with — professional, responsive and reliable

Ruben Meijer / Program Manager | Jun 18, 2026

Overall we had a good experience working with 21CN.

It has made a real difference to how our team works day to day. There were some early misunderstandings on requirements that took a few rounds to sort out. I would recommend 21CN to anyone looking for a dependable UI/UX Design partner.
