Dedicated Team Augmentation Review from Leonid Viktorov
I am the CEO of Biz Adviser, a business consulting company. We work with companies on strategic business initiatives, digital transformation, and improving business performance. We partnered with UASOFTDEV when we urgently needed additional engineering capacity. I was looking for proven senior developers and did not have time to spend weeks sourcing candidates and conducting multiple interviews. UASOFTDEV offered to provide vetted Ukrainian developers within 60 hours, which was exactly what we needed. The team provided senior engineers with strong technical expertise and excellent communication skills. We worked with developers across PHP, Node.js, Python, and React, depending on the project requirements. They were reliable, proactive, and able to understand not only the technical tasks but also the broader business context. The developers contributed to several important initiatives, including the implementation of an AI agent, and helped us move projects forward faster while keeping development costs under control. UASOFTDEV delivered what they promised. The process was straightforward, communication was reliable, and the developers were able to start working quickly without compromising on quality. The pricing was a good fit for our budget, and the overall value for cost was excellent. I also appreciated the cultural fit and the team's ability to communicate effectively and take ownership of their work. I would definitely recommend UASOFTDEV to companies looking for reliable staff augmentation with senior Ukrainian developers. They are a trustworthy partner that can provide strong engineering talent quickly and help businesses deliver important initiatives without the overhead of a lengthy hiring process.

Dessi Nikolova's Review Sourced from Google
Attention! - Big scam!After 3 months of communication back and forth ( with multiple people) , I ended up paying almost $5000 for a website that looks like crap.Had to have a new one built since there is no one to take responsibility for the work they have done. After trying for another 2 months to communicate and “ fix” the website, I finally gave up. They needed more, and more money to “ fix” a simple informative site ( that’s all I wanted)… And since I had already invested so much, it was hard to give up and I kept hoping and paying more and more until they drained my account. Being unable to pay someone else, I had no choice but to try building the website myself. I went to Godaddy and did it! Turned out it was so easy to do - multiple choices of templates! I found one that also allows me to take payments and make appointments online. And I paid $179 for it. Beautiful website! Please save your hard earned money and don’t even make attempts to contact these scammers.This, by the way, is the only bad review I ever left for someone and that should tell you a lot.Good luck!

Software Development Review from Kerry Cooper
We partnered with Softellar to modernize our patient records management system and improve overall healthcare delivery, and the results have been outstanding. The project was essential for us, especially during the pandemic, when remote care became a necessity. Softellar's team developed a comprehensive healthcare solution that seamlessly integrated a central patient records management system, telemedicine capabilities, remote health monitoring features, and full regulatory compliance.Their deep understanding of our unique needs and workflows allowed them to customize the solution effectively, creating a user-friendly system that reduced delays and significantly improved patient care. The telemedicine functionality ensured uninterrupted care during the pandemic, while remote health monitoring provided us with valuable insights into patient conditions, enabling proactive interventions.What impressed us most was Softellars flexibility and responsiveness. They delivered the project on time, made adjustments when needed, and ensured the system worked perfectly with our existing infrastructure. Their attention to detail and commitment to user experience made the system easy to adopt with minimal training for our staff.

Softellar has been a game-changer for LoanStreet, providing exceptional IT Staff Augmentation that seamlessly integrated with our team.

Alana Muller's Review Sourced from Google
WOW! Working with Crema was a dream come true -- literally! Rarely have I had the opportunity to engage with a partner who so actively listens to its client's vision, considers ways address the request, then magically brings it to life with such finesse... that's exactly what Crema did. With a tight turnaround time and a very public launch, Crema created a beautiful user interface, backend database, and promotional display that activated my product and made it fun and easy to use while perfectly representing my brand. I am so grateful to Crema and will continue to seek opportunities to work with this innovative, creative, and positive group of professionals.

Evan Harmon's Review Sourced from Google
Every experience I've had with Crema has always been a positive one. And every employee I've met there have been incredibly nice, thoughtful, and great to talk to. They have a very cool office space in the Crossroads with great views of KC that just makes you want to hang out there! Crema seems to highly prioritize their company culture by putting on events and having a heathy work/life balance. In short, they seem to really care about people and that carries into their work, judging by how I was able to see their process for developing solutions for their clients at a workshop they held. Using the design sprint methodology, and healthy doses of design thinking, humanistic perspectives, diversity, and pragmatism, they clearly have spent a great deal of effort honing a highly efficient development strategy that makes finding creative solutions a reliable science. It gave me a lot of ideas to bring back to my own projects and meetings! I definitely recommend their design sprint workshop and can only imagine they would be a great company to have tackling your company's challenges.

The Crema office is very cool. Lots of modern touches with a great view of the Kauffman Center for Performing Arts. I recently attended a Design Sprint workshop and had a great time! It was a unique experience and a great tool for solving even the most complex problems. I'm hoping to utilize it in my current role. Justin was a great facilitator and I would recommend using Crema for any Design Sprint needs or even attending the workshop yourself. It was also a great networking opportunity. Highly recommended!

I ordered the DNC scrub they never delivered. I am still waiting for my refund. Ordered on a Saturday got an email stating " our offices are closed we will reopen bla bla bla" After a few days of hassle they decided to refund however so far the money did not show up in my credit card. I don't recommend doing business with this company.

What services do app development companies typically offer?
App development companies usually handle strategy, UI/UX design, development, testing, launch, and ongoing maintenance. Some also provide product research and app store optimization.
How much does it cost to hire an app development company?
App development agencies typically charge between$30,000 and $500,000+, depending on the scope and complexity of the project.
Typical custom app costs by scope include:
Simple app: $10,000 to $35,000
Medium-complexity app: $35,000 to $150,000
Complex app: $150,000 to $300,000+
How long does it take to develop a mobile app?
Most apps take around 3 to 7 months to develop, though the timeline depends on complexity, features, technology, and the development team. Changes in scope, integrations, and testing requirements can also extend the timeline.
Simple apps: a few weeks to 3 months
Medium-complexity apps: 3 to 7 months
Complex apps: 7 to 12+ months
How do I choose the right app development company?
Look at relevant experience, past projects, technical expertise, communication, and post-launch support. The company should also understand your business goals and target users.
What should I look for in an app development company’s portfolio?
Check whether they have built apps similar to yours and review the usability, design quality, and functionality of their work. Pay attention to projects in your industry or with comparable technical requirements.
What track record should I look for in an app development company?
Ask for launch counts, instead of project counts. An app development company that has shipped dozens of live apps has already solved App Store review, retention, and post-launch iteration. Designli, for example, lists more than 200 product launches and traces its process back to Applits, an app studio its founders ran before the agency existed.
What are the top mobile app development companies in 2026?
The top mobile app development companies in 2026 are:
