After facing challenges with my online store's functionality, I reached out to Retrocube for help. They proposed a comprehensive e-commerce app that integrates payment processing, inventory management, and AI features all in one place. The development process was smooth, and the team was always available for questions. The new app has significantly improved my customer engagement rate.

I do not recommend RetroCube for app development. I have been working with them for over two years, and despite paying over $37,000—well beyond the agreed-upon amount—my project remains incomplete. Communication has been inconsistent at best, and I’ve had to constantly follow up just to get vague or delayed responses. Most recently, I spoke with Andrew regarding a refund due to the extended delays and lack of delivery, and he was completely dismissive and unwilling to cooperate. This experience has been incredibly frustrating and disappointing. I feel taken advantage of and want to prevent others from going through the same thing. If you’re looking for a reliable, transparent app development partner, I strongly urge you to look elsewhere.

I have been in the real estate business for 26 years, with over 1,000 agents in the Denver, Colorado market. Before meeting with RetroCube, I was searching for a robust app development company that included a desktop version. It was challenging to come to an agreement on my needs with multiple companies. However, after meeting with RetroCube, we decided to proceed with them, and the results have been nothing short of perfection. I highly recommend contacting RetroCube for any mobile app development.

I will share my experience with Technbrains aka Koder Labs a year out from their service. I hired this company in May 2024 to Develop a two sided market app for my business. They worked off of a feature and product list I created and brought from another developer. They claimed they can complete this within three months and make sure it is scalable and viable for growth. I will say that the team itself was very organized and structured initially, and they had great communication. I had a great relationship with two of the members of their team. I ended my business with coder once they were near completion and I asked for a quote for two final Features that were important for my app, which included a background check API integration, and a stripe payment integration. They quoted me over $10,000 for these two features which I felt was too high. I received much lower quotes when I shopped around with other developers. But this is not even half of the issue. Soon after I found a tech cofounder to join forces with me. The app was not set up correctly in the backend, and we have allowed several developers to check out our servers and backend to which they have all said the same thing. The backend is a mess and some developers refused to even touch it because it was so confusing. My notifications have been wonky since I left them last year. We just found the root of the cause is the way they set up the sqs to 50 minutes Instead of 50 seconds. This has caused an expensive and ongoing issue for the last eight months. In addition to this they name so many folders do not delete. They also used fire base and a WS, which are too conflicting back in servers. The entire set up of my app is unnecessarily complicated. And has been a constant expensive fix for me. there were many features that are hardcoded, which were not necessary. Which means I cannot change very very simple things in the app, especially when they were using flutter flow to develop the app. I do not recommend this company to anyone. It is clear that they purposely made the app to be complicated, so that no other developer would want to touch it and I would end up back with them. To top it off, there were some very, very sloppy mistakes at the end of our business when they knew I would be leaving them due to the expensive quote. It seemed as they were in a hurry to finish off with me, so they made less time to properly ensure the app was in a good standing. On top of all this, when I made them aware of these issues, they would never accept any kind of accountability. If you want a good quality app, I would recommend you spend a little more on something that is worth it. In the end you will end up paying far more For fixing stupid unnecessary mistakes for months or even years after it has been developed. I also want to know that none of the employees are actually stationed here in the US. They are ALL offshore workers. In addition to that, look at all of their reviewers who gave them five stars. They are all fake accounts with only one review, which is just for TechNBrains.

Our e-commerce platform in Dallas needed a robust mobile app to enhance customer engagement, and we couldn’t be happier with the outcome.
