      Alliance Systems purchased the company that developed our website. We had an issue that the "customer service" person working to solve and promptly accused our company of not paying past due invoices. We proved the invoices were paid and their "Chief Experience Officer" sent us an email that their employees would not be harassed or bullied. I cannot recommend enough to avoid this company.

      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.

      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!

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.
