iOS & Android App Dev for Hair Stylist App

They’re really great. They keep me in the loop on everything. Anything I don’t like they respond to quickly. It’s easy for me to correct things that aren’t right. They did a great job breaking down in layman terms the route we should go. I don’t have a technical background but they familiarized us with the different ways to program our solution. This ensured that we didn’t have to redo any of the work. They’re upfront about how long things will take. We were impressed with how they courted us and their talent. They’re trying to see us make it through. It feels like we’re one team. I’m very comfortable with them.

App Dev for Consumer Money Service Company

At times, we only had 50% of the requirements laid out because we were still trying to determine which direction to go in, but Mobcoder was open to working with whatever we had. They provided helpful timeline reminders, and they quickly responded to our questions. Communication was good; they set up a Slack channel, and we communicated with Marc just about every other day.

The team at AppIt is incredible. Amanda was accessible frequently and went above and beyond to make us feel supported throughout the process. We did not expect the CEO to be so involved, but it was a gift and made a scary process less scary. Laura, our project lead, is fantastic. She was incredibly patient with our lack of knowledge about building an app. She set up and led our meetings, helped build certain features, made sure other team members were on their game, and took time to address needs and concerns as they came about.

Web Dev & UX/UI Design for Marketing Company

A project manager was assigned to the team. Weekly meetings were held, and specific items were assigned to each sprint. Once the sprint was concluded the team would meet to review and test new development. The team is very collaborative and able to deliver innovative solutions for all our business needs.

Mobile App Dev for Tech Start-Up

Absolutely flawless, flexible and on time. If we disregard the fact that delivery and output was agreed on, we were quite impressed by the professional operation, process and in general sense of collaboration. Also keeping track of tasks, meeting notes and assignment of tasks was smooth and simple. For us it was okay, since TV was quick at responding, and bc we're a quite small team and a startup. But in an ideal world, I would prefer to use whatever software for collaboration to make sure things are documented and assigned, instead of being potentially lost in clutter of Slack (e.g. Gitlab which was already being used).

It was easy to communicate with their project manager, and they frequently updated us. We spoke over the phone at least once a week and used Slack to chat. Overall, I was impressed by the team’s timeliness.

Beyond all of that, Edify's commitment to the education sector is very admirable and extremely useful when translating technical specs into user-facing features. Also, as a rule, Edify's management team has also been open, transparent, and willing to work through issues together, which is something we value greatly in the relationship.

Internal Database Dev & Design for Pet Health Company

I also find their ticketing system interesting because I can tap into their systems — from product management to user experience and design tools — without having to manage it 100% of the time. I think their whole approach to these open-source platforms enabled us to have a level of transparency that I wouldn’t have if everything was on a custom build and housed with them.

Custom AI Solutions Dev for AI Automation Co

The team was very attentive to our needs, actively collaborating with us during the requirements-gathering phase to fully grasp our objectives and challenges. They kept communication channels open throughout the project, inviting feedback and making necessary adjustments. For instance, when we suggested additional features to enhance the AI applications, they promptly integrated those changes without causing significant delays.

iOS App Development & Design for Theater Production Company

iRoid Solutions managed the project in a responsive and collaborative way. We communicated regularly throughout development, and they were always willing to discuss feedback, clarify requirements, and make adjustments as the product evolved. Because this was a custom app with many user flows, admin features, and post-launch refinements, the timeline was naturally iterative. Some features required additional rounds of revision, but the team stayed engaged and continued working through issues until they were resolved.

iOS App Development & Design for Theater Production Company

What impressed me most was how collaborative and supportive the team was throughout the process. This was my first time building an app, and iRoid Solutions helped make my vision a reality while also explaining the technical processes and decisions in a way that made me feel informed and involved. They never made the project feel overly intimidating or inaccessible. Instead, they worked with me as a true partner, helping me understand what was being built, why certain decisions mattered, and how the product could continue improving.
