Reliable Mobile App Development Partner That Delivered What They Promised

Jess Evans / Co-Founder | Sep 13, 2026

300.codes did an excellent job for us. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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. Overall, a team we trust and plan to keep working with.

Project summary

We hired 300.codes to develop a field-staff app with offline mode that syncs back to our main system. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 4-month engagement.

Capable Data & Analytics team — happy with the end result

Emma Wilson / Founder | Aug 07, 2026

We got a good result in the end, but the road there had a few bumps. 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 dealt with the same core team throughout, so we did not have to keep re-explaining things.

The result looks great and performs well, and our internal team found it easy to take over. Estimates on a few features were optimistic and those took longer than planned. Happy to recommend them.

Project summary

We engaged 300.codes to set up a data warehouse and reporting layer for our leadership team. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 6-month engagement.

Lucy Lloyd / Managing Director | Jul 25, 2026

Our experience with 300.codes was really positive from start to finish. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

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.

They listened, asked the right questions, and delivered

Heather Ramirez / Marketing Director | Jul 19, 2026

We were happy with the final result. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. A couple of milestones slipped by a week or so, mostly around testing. We would definitely work with them again.
