      Phenomenal team to work with. From Sales to Engineering, Customer Service and at the highest level of leadership, the DualBoot partner team is simply great. They are consistent and interested in your success. Once their engineering team has learned your stack, you can't tell from inside to external resources. Work just gets done. I recommend them w/o reservations; start-up or well established firm, you are in great hands with the DualBoot team!

      We have been working with Dualboot for close to a year and the process is perfect. The team is responsive, knowledgeable and talented. The Dualboot team has taken the idea of software and allowed it to be simplified for non-tech minded people. I would recommend them to anyone.

How long does it take to develop a mobile app?

  • 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.

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.
