Strong Technical Skills and a Very Responsive Mobile App Development Team

Huda Al Harbi / Managing Director | Sep 30, 2026

doppelt.digital did good work for us, and we would use them again. 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. 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 Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail. Overall, a team we trust and plan to keep working with.

Project summary

doppelt.digital was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. The project was split into milestones, with a working build shared at the end of each one. The project took roughly 4 months from kickoff to launch.

Solid Mobile App Development Work With Clear Communication Throughout

Eric Patel / CTO | Aug 25, 2026

We were very happy with how this project went. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project.

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

Project summary

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?

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

Why did you choose this company over other providers you considered?

They had relevant experience in Advertising & Marketing and their proposal was the clearest of the ones we received.

They understood our goals quickly, partly because they had worked with Advertising & Marketing clients before.

How was your overall experience with their communication and project management?

Communication was good overall and improved further once we settled into a routine.

Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.

Capable UI/UX Design team — happy with the end result

Divya Menon / Director | Apr 26, 2026

The final product works well for us, although the process could have been smoother. 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

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.

I would recommend doppelt.digital to anyone looking for a dependable UI/UX Design partner.

Project summary

Our company worked with doppelt.digital 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. The engagement ran for about 5 months.

Strong Technical Skills and a Very Responsive AI & Machine Learning Team

Lukas Richter / Senior Engineering Manager | Mar 25, 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. 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.

We are already discussing the next phase with them.

Project summary

Our company worked with doppelt.digital to add an AI chatbot to our support site that answers questions from our help docs. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 9-month engagement.

Professional team that made a complex project feel manageable

Rachel Hughes / IT Director | Mar 17, 2026

doppelt.digital did good work for us, and we would use them again. 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.

The Blockchain Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Their team changed one developer midway, which slowed things down for a couple of weeks. Happy to recommend them.

Priya Coleman / Senior Engineering Manager | Mar 08, 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The result looks great and performs well, and our internal team found it easy to take over. We had to follow up a few times on smaller bug fixes after launch. I would recommend doppelt.digital to anyone looking for a dependable Mobile App Development partner.
