Appreciation From Clients

Riccardo Petrachi

United Kingdom

We searched online for app developers that had an extensive experience in mobile app development as well as a strong presence in the market. We chose Space-O specifically because of the up-close experience we had with another app they had developed and we wanted to achieve the same high level of standards, quality, and satisfaction. We were looking for brilliant experts and we found them.


Douglas Laver


The Space-O team were great to work with. Every part of the process went as per the agreed schedule, and the finished prototype met, and in most cases, exceeded my expectations. While Space-O wasn’t the most price competitive of the quotes I received, the quality of their work, professionalism, and product, was well worth the additional cost. Highly recommend, and will continue to use their services for future projects.


Ashton Asherian
