      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!

Frequently Asked Questions

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.
