Great Experience With Devil App Development on Our Blockchain Development Project

Luke Kelly / Project Manager | Oct 03, 2026

Devil App Development did an excellent job for us. 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. 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. Happy to recommend them.

Project summary

Our company worked with Devil App Development to develop and audit smart contracts for a tokenized loyalty program. Their team handled planning, development and QA, with our product owner signing off each milestone. The engagement ran for about 8 months.

The project went well overall. 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.

Devil App Development Delivered a Quality UI/UX Design Solution on Time

The project went well overall. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Since launch, everything has been stable and our team has adapted to it quickly. There were some early misunderstandings on requirements that took a few rounds to sort out. Happy to recommend them.

Would happily work with them again

Brandon Hughes / Owner | Jul 09, 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.

Reliable AR/VR Development Partner That Delivered What They Promised
