Great Experience With Mark Tolmacs on Our Mobile App Development Project

Heather Fisher / Founder & CEO | Sep 15, 2026

I would rate this engagement highly on almost every front. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We are already seeing better numbers than before the project. Happy to recommend them.

Project summary

We engaged Mark Tolmacs 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. Overall it was a 6-month engagement.

Great team to work with — professional, responsive and reliable

Georgia Kelly / Co-Founder & CTO | Jul 22, 2026

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

The result looks great and performs well, and our internal team found it easy to take over. We would definitely work with them again.

Project summary

We engaged Mark Tolmacs to take over manual and regression testing before each release. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 6-month engagement.

Would happily work with them again

Andre Sullivan / Founder | Jun 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

We are already seeing better numbers than before the project. We would definitely work with them again.

A reliable long-term partner for our tech needs

Nicole Morgan / Project Manager | Jun 21, 2026

The project went well overall. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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 took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The Quality Assurance & Testing 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 partnered with Mark Tolmacs to set up automated testing for our web application. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 6 months.

Good value and a team that genuinely cares about the result

Ryan Coleman / CEO | Mar 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent.
