Zumar Labs Reviews

Good work overall, with a few bumps along the way

Felix Müller / Founder & CEO | Oct 05, 2026

We got a good result in the end, but the road there had a few bumps. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

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. We are already discussing the next phase with them.

Project summary

We engaged Zumar Labs to build iOS and Android apps for our customers, including booking, payments and push notifications. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 6 months.

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

We had tried to do this internally and it stalled. We needed specialists to build iOS and Android apps for our customers, including booking, payments and push notifications.

What services did the company provide for your project?

Mainly Mobile App Development. They also helped with the technical planning and a few integrations with our existing tools.

Good. Weekly calls, regular updates and a shared board meant we always knew where things stood.

Yes. The only extra cost came from features we added ourselves, and they quoted those fairly.

Our team saves several hours a week, and we have had very few issues since launch.

Professional UI/UX Design Team, Smooth Delivery From Start to Finish

Lerato Botha / Product Manager | Sep 10, 2026

We were happy with the final result. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Project summary

Our company worked with Zumar Labs to redesign the user experience of our SaaS product. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 7 months.

Solid delivery, though timelines needed some pushing

Sam Thompson / Head of Engineering | May 22, 2026

We got a good result in the end, but the road there had a few bumps. 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

It has made a real difference to how our team works day to day. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.

Great team to work with — professional, responsive and reliable

Lukas Schmidt / Director | May 18, 2026

The project went well overall. 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. Documentation at handover was a bit thin and we had to ask for more detail. I would recommend Zumar Labs to anyone looking for a dependable Mobile App Development partner.

Project summary

We hired Zumar Labs 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. Overall it was a 5-month engagement.
