Reliable Mobile App Development Partner That Delivered What They Promised

Felix Weber / Director | Oct 20, 2026

One Box did an excellent job for us. 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.

It has made a real difference to how our team works day to day.

I would recommend One Box to anyone looking for a dependable Mobile App Development partner.

Project summary

We hired One Box to rebuild our existing mobile app, which had poor reviews and frequent crashes. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 2 months.

Redwood Wear GmbH is a Fashion & Apparel business in Cologne, Germany. As Director, I was responsible for this project on our side and the main contact for One Box.
What specific problem or business challenge led you to hire this company?
Our team was spending too much time on manual work. The goal was to rebuild our existing mobile app, which had poor reviews and frequent crashes so they could focus on customers.
What services did the company provide for your project?
Mobile App Development, including planning, development, testing and launch support.
Why did you choose this company over other providers you considered?
We compared three or four agencies. One Box asked the best questions and had good reviews from past clients.
How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Fashion & Apparel clients before.
How was your overall experience with their communication and project management?
Very responsive. We usually heard back the same day, even with the time difference.
Did the company deliver the project on time and within your expected budget?
Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.
What tangible results or business impact have you seen since the project was completed?
It is still early, but the numbers are trending in the right direction and the system has been stable.

Yes, I would recommend them and we plan to work with them again.

Quality work, a little slower than we planned

Laura Koch / General Manager | Oct 05, 2026

Overall the project was a success, though it was not without some challenges. 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

It has made a real difference to how our team works day to day. There were some early misunderstandings on requirements that took a few rounds to sort out.

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

Project summary

We hired One Box 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 8 months from kickoff to launch.

The consistency. Same team, same standard, from the first week to the last.
Would you recommend this company to others, and would you work with them again?
Definitely. We have already started talking about the next phase.

Professional team that made a complex project feel manageable

Sophie Lloyd / Operations Manager | Sep 07, 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Project summary

We engaged One Box to set up a sensor network and alerts for our cold storage facilities. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 7 months.

Good work overall, with a few bumps along the way

Harry Edwards / Program Manager | Aug 18, 2026

The final product works well for us, although the process could have been smoother. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Since launch, everything has been stable and our team has adapted to it quickly. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Project summary

We partnered with One Box to build a demand forecasting model on top of our sales data. The work covered requirements, design, development, testing and launch support. We worked together for around 3 months.

Good results, communication improved as the project went on

Eric Hughes / Head of Digital | Jun 21, 2026

The final product works well for us, although the process could have been smoother. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

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. If you need a team that communicates well and delivers, they are a good choice.

Great Experience With One Box on Our Software Development Project

Maya MacDonald / CEO | Apr 02, 2026

Overall we had a good experience working with One Box. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They shared working builds regularly, so we could test early and give feedback before things were locked in.

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. Happy to recommend them.

Project summary

Our company worked with One Box to rebuild an internal order management system that had outgrown its original design. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 9 months.

Great team to work with — professional, responsive and reliable

Chris Reed / Marketing Director | Feb 10, 2026

Overall we had a good experience working with One Box. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We are already seeing better numbers than before the project. Estimates on a few features were optimistic and those took longer than planned. I would recommend One Box to anyone looking for a dependable IT Consulting partner.
