Frequently Asked Questions About App Development Companies
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.
