Mobile App Development Review from Guiulianna Cespedes
Our company needed an Android app that could support a mental health platform in a way that felt calm, easy to use, and dependable for daily users. We hired Simpalm to build that product in Kotlin and help us move from concept into something real customers could use. For us, trust and simplicity mattered more than packing in too many features.
They took a fairly hands-on role, which was helpful because we were still making product decisions as the project moved. Some weeks I was deeply involved reviewing screens, and other weeks they pushed things forward on their own. That balance worked well. They would usually come back with two or three options instead of just asking what we wanted.
We did hit one rough patch around notifications where the first version didn’t behave the way we expected, so that had to be revisited. They fixed it without making the process difficult.
The finished app runs smoothly, feels organized, and gave us a much stronger mobile presence on Android. Most importantly, early users found it approachable rather than overwhelming, which was exactly what we wanted.

Mobile App Development Review from Amanda Chalofsky
My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.

Mobile App Development Review from Matt Rudnick
Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

Software Development Review from Jake Mackay
For quite a long time we took orders by e-mail or personally from customers. It took a lot of time, as we either made layouts by hand or printed them according to the vague requirements of clients. All these difficulties have pushed us to take a step towards the digital transformation of our business. The team of Five Jars has developed a frontend and backend for our web tool to create print layouts. The team is not afraid to take on difficult tasks!

Responsive Review from Anthony North
I was looking for companies that had experience with large educational platforms. There are some really big players in the eLearning market in Five Jars' portfolio, so I trusted their development experience. After all our platform has become more attractive to users. Over the past year, we have noticed a significant increase in daily visits, so much so that we even had to change hosting. Five Jars helped us with that too!

Small Business Review from Colin Knox
I'm satisfied with the MVP we've done with the Five Jars team. I am currently looking for an investor for this project. I love working with professionals when I don't have to dive into a whole area that I don't know. Working with the Five Jars was a real partnership where the other side fulfilled their obligations without my constant checks.

We just wrapped up a several-month project with the team at Kodexo Labs Austin and they were fantastic to work with. The project was complex, but they stayed patient, responsive, and super professional the whole time. Their team made everything feel smooth and well-organized, and the end result really speaks for itself. Definitely one of the best software development companies in Austin and we're already planning our next project with them.

Worked with Kodexo Labs Austin on a custom app for our delivery service, and they really impressed me. We wanted to integrate some AI features to predict delivery times and optimize routes they not only made it happen, but explained the tech in a way that actually made sense. Communication was smooth, no BS, and they stuck to the timeline. If you need mobile app development in Austin, especially anything AI-related, I’d definitely recommend them.

Product Design Review from Jonas Weber
We worked with Uitop to create an interface for our product. The challenge of our product is IoT integration and deep analytics. They created an interface from scratch and supported us with development. They do not just do the interface, but they explain to us why we should use such elements. They started with a design that perfectly captured what our product was all about. It was user-friendly and looked great. We are totally satisfied with the results!
