Skilled Mobile App Development Team That Understood Our Business

Noah Tremblay / Founder | Sep 24, 2026

INSSIO 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Since launch, everything has been stable and our team has adapted to it quickly. A couple of milestones slipped by a week or so, mostly around testing. We would definitely work with them again.

Project summary

We engaged INSSIO to develop a field-staff app with offline mode that syncs back to our main system. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 7 months from kickoff to launch.

INSSIO Delivered a Quality Mobile App Development Solution on Time

Pieter Nkosi / Co-Founder | Sep 03, 2026

We were happy with the final result. 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.

We launched on schedule and have not had any major issues since. There were some early misunderstandings on requirements that took a few rounds to sort out. Happy to recommend them.

Overall we had a good experience working with INSSIO. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We launched on schedule and have not had any major issues since. Documentation at handover was a bit thin and we had to ask for more detail.

Great Experience With INSSIO on Our Mobile App Development Project

Kelly Hayes / Director of IT | Jun 15, 2026

I would rate this engagement highly on almost every front. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

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

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

Honest advice and solid execution

Jess Shaw / Head of Engineering | Jun 04, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Feedback from our customers has been very positive so far. Happy to recommend them.

Good results, communication improved as the project went on

Rahul Verma / Founder & CEO | May 21, 2026

We got a good result in the end, but the road there had a few bumps. 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

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

Project summary

Our company worked with INSSIO to build iOS and Android apps for our customers, including booking, payments and push notifications. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 3 months.

Overall the project was a success, though it was not without some challenges. They were upfront about what was realistic within our budget, which helped us prioritise the right features.
