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 Theodore Patestos
We’ve worked with Saad and his team for close to a year now. They’ve been diligent throughout the process, responsive and communicative. They came in mid-stream to save the project from another development team that didn’t live up to their commitments. I would highly recommend Plego to any company looking to see things move forward on a stalled project or looking for a team that will jump in and start to get things done.

Web Development Review from Tyler Tomlinson
Saad and his team were a great group of people to work with. Our scenario was probably unique to this group, and they tackled the project with a full head of steam and with no hesitation. It has been a pleasure working alongside his team.

Highland Reviews & Testimonials

UI/UX Design Review from Audrey Thomas
Highland is a great partner. The sought to deeply understand our product, customers, and pain points and built a number of forward looking opportunities for us in addition to the tight scope of our project. Proactive, thoughtful, responsive, and flexible. We are a small team and found lots of value in working with Highland to get our UX refresh project up and running.

UI/UX Design Review from ✨ Liz Pisney ✨
We recently partnered with Highland on research and prototypes for a new information architecture on a volunteer resources site for our Chapter leaders. Having over 3000 volunteers around the globe can introduce a lot of nuance and complexity to research and design processes. The team at Highland handled it all skillfully - focusing on how to deliver the most clarity and usability to our audience. 10 out of 10, I would recommend working with the Highland team!

Webflow Review from Lee Wiensch, CAE, CFRE
We had a great experience working with the team at Highland to develop a new website for the Thoracic Surgery Foundation, a charitable organization aimed at advancing heart and lung health for all. Highland worked with us to re-imagine a dated website with limited functionality, and developed a a gorgeous new site that beautifully reflects the vitality of the organization. We anticipate that our award applicants, donors, surgeons and grateful patients will be able to easily navigate the new site and have a much-improved user experience. Jeff Blanchard and his team were exceptionally good listeners, and worked hard to create solutions for our complicated awards program. They provided good training to our team throughout the process so that we have been able to keep things updated and easily make changes now that the site has launched. I am grateful for their patience and very quick turnaround as we juggled a new strategic plan and new branding, all at the time of the website creation. I have been continually impressed with the expertise and the innovation that Highland brings to a project like ours. It was a pleasure to launch this site -- on time and on budget -- with their excellent work and support.

Walter White's Review Sourced from Google
Initially, The App Founders showcased a pro-found grasp of blockchain technology and its practical applications. They adeptly elucidated intricate concepts in a manner that resonated with my non-technical background, facilitating smoother communication and active involvement in developmental discussions.
Dustin Wheeler's Review Sourced from Google
it was such a pleasure working with App Founders and just how easy and professional they were. I quickly realized how the industry is full of thirsty, needy bots and scammers I’m trying to get your attention, but tons of unsolicited phone calls and texts. Dealing with these guys was a breath of fresh and definitely showed up in value above all the rest.
Munna Alam's Review Sourced from Google
Got to say, The App Founders really impressed me! They totally nailed the design for my mobile game. Can't wait to team up with them again to make and promote the game. Definitely recommending them to anyone looking for top-notch game development services!
