Good results, communication improved as the project went on

Huda Al Harbi / Owner | Oct 14, 2026

The final product works well for us, although the process could have been smoother. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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. Estimates on a few features were optimistic and those took longer than planned.

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

Project summary

CAST SRL was brought in to improve our release process, which involved a lot of manual steps. The project was split into milestones, with a working build shared at the end of each one. The project took roughly 7 months from kickoff to launch.

CAST SRL Delivered a Quality Mobile App Development Solution on Time

Ben Hughes / Head of Digital | Oct 13, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

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

We partnered with CAST SRL 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. The project took roughly 5 months from kickoff to launch.

Dependable AI & Machine Learning Partner for a Growing Agriculture Business

Rahul Agarwal / Co-Founder & CTO | Sep 16, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We launched on schedule and have not had any major issues since. We would definitely work with them again.

Honest advice and solid execution

Khalid Qureshi / Director | Jul 19, 2026

Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Capable AI & Machine Learning team — happy with the end result

Saud Al Harbi / Co-Founder | Jul 15, 2026

The final product works well for us, although the process could have been smoother. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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.

Since launch, everything has been stable and our team has adapted to it quickly. There were some early misunderstandings on requirements that took a few rounds to sort out.

We are already discussing the next phase with them.

Project summary

Skilled Mobile App Development Team That Understood Our Business

Zoe Murphy / Head of Digital Transformation | Jul 09, 2026

We were happy with the final result. 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks. I would recommend CAST SRL to anyone looking for a dependable Mobile App Development partner.

Project summary

CAST SRL was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. The work covered requirements, design, development, testing and launch support. We worked together for around 4 months.
