Solid Mobile App Development Work With Clear Communication Throughout

Amit Mehta / Director of IT | Sep 03, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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 were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Since launch, everything has been stable and our team has adapted to it quickly. I would recommend Lumen21, Inc to anyone looking for a dependable Mobile App Development partner.

Project summary

Lumen21, Inc was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 4 months from kickoff to launch.

Exceeded our expectations on quality and communication

Ashley Wallace / Senior Product Manager | Jul 29, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

We launched on schedule and have not had any major issues since. Happy to recommend them.

Overall we had a good experience working with Lumen21, Inc. 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.

Tobias Richter / Founder & CEO | Jun 07, 2026

Overall the project was a success, though it was not without some challenges. Communication was consistent.

Strong Technical Skills and a Very Responsive E-commerce Development Team

Arjun Mehta / Director | Feb 22, 2026

The project went well overall. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Quality work, a little slower than we planned
