Professional Mobile App Development Team, Smooth Delivery From Start to Finish

Omar Fernandes / Managing Director | Sep 24, 2026

I would rate this engagement highly on almost every front. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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. Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with GN Sistemas to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 2-month engagement.

We're a mid-sized Retail & E-commerce company based in Sharjah, UAE. I'm the Managing Director and I oversaw the project from start to finish.

What specific problem or business challenge led you to hire this company?

Our existing setup was holding us back. We wanted to develop a field-staff app with offline mode that syncs back to our main system before our busy season.

Delivered on time and stayed involved after launch

Laura Hoffmann / IT Director | Aug 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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.

Feedback from our customers has been very positive so far.

Happy to recommend them.

Project summary

We hired GN Sistemas to build the multiplayer features for our existing game. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 7-month engagement.

We were very happy with how this project went. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

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.
