Exceeded our expectations on quality and communication

Harry Lloyd / General Manager | Sep 24, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We are already seeing better numbers than before the project. I would recommend EFFECTIVE ONLINE GROUP s.r.o. to anyone looking for a dependable Mobile App Development partner.

Delivered on time and stayed involved after launch

Sneha Gupta / Senior Engineering Manager | Jul 17, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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 were upfront about what was realistic within our budget, which helped us prioritise the right features. 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.

We would definitely work with them again.

Great Experience With EFFECTIVE ONLINE GROUP s.r.o. on Our IT Consulting Project

Jason Johnson / CEO | Jun 05, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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.

We launched on schedule and have not had any major issues since. We had to follow up a few times on smaller bug fixes after launch.

We would definitely work with them again.

Project summary

We partnered with EFFECTIVE ONLINE GROUP s.r.o. to assess our architecture before a major product rebuild. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 6 months.

Abdullah Al Otaibi / CEO | Jun 04, 2026

Good results, communication improved as the project went on

Rohan Menon / Project Manager | Mar 30, 2026

The final product works well for us, although the process could have been smoother. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

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.

We are already discussing the next phase with them.

Project summary

We hired EFFECTIVE ONLINE GROUP s.r.o. 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. We worked together for around 8 months.

Solid delivery, though timelines needed some pushing

We got a good result in the end, but the road there had a few bumps. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

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. We would definitely work with them again.
