I really like their approach to building my app. They have been very attentive and responsive throughout our engagement. It's not always easy to find partners who are open minded enough to build something from scratch without using off-the-shelf products or libraries. And it is even harder when you need your project done quickly. Bluemungus was able to deliver an excellent product with minimal changes required after launch. The quality of code written by them has helped us save time and money. We've also seen great results from working together with their team. Their support staff is extremely helpful and knowledgeable about all aspects of app development. There were no issues at all during this process. But if there had been any problems they would have solved them immediately. As mentioned above - quick turnaround times, high quality apps built by experts.
