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.

Web Development Review from Victoria Lee

I can count on one hand the number of companies Ive worked with in my career that possess the same level of dedication, responsiveness, attention to detail, and trustworthiness as that of an internal team and thats because theres only one: Handbook.First and foremost, Id like to say that if you're considering working with Handbook for your design and/or website development needs, you absolutely will not regret it. The Handbook team goes beyond simply executing our requests, which has not only been refreshing but has also been key to our growth as an online SaaS business.Handbook genuinely cares about our user experience, website performance, and broader business goals. Instead of just implementing what we ask for, they actively evaluate our needs and offer thoughtful recommendations to improve our outcomes.In addition to the quality of work and forward-thinking perspective, we know that we can count on Handbook to be there when we need them. From countless late-night sale asset takedowns to weekend staging QAs so we can feel confident about Monday morning launches, I have never experienced this level of communication and dedication from a company.I would recommend Handbook time and time again to absolutely anyone in need of web development, design, or messaging support. These guys are a rare find and your only regret will be that you didn't start working with them sooner.
