FAQs
How expensive is it to build a mobile application with leading US businesses?
Pricing is diverse, and simple applications cost around $50,000-100,000, more complex applications that require integration into the back-end cost around $100,000-300,000, and the most complex applications cost on the high side, around $1,000,000.
What is the average time to create a mobile application?
Project complexities determine the timeline of development: a simple MVP is 3-4 months, medium complexity applications with custom functions last 5-7 months, and complex enterprise applications may take 9-18 months to complete. These Mobile App Development Companies in the USA apply agile practices to create incremental value during development.
Which development should I use: native or cross-platform development?
Native development (Swift on iOS, Kotlin on Android) is the most performant and platform-specific, and is more expensive. React Native (Cross-platform frameworks, Flutter) is developed by 30-40% less and delivers good performance to most applications.
What are the cost items that I need to budget after the app release?
Budget 15-20% of the initial development cost/annual on maintenance, such as server hosting ($500-5,000/month), bug fixes, OS updates, security patches, and minor feature additions.
What about my idea of an app: can I keep it confidential when I collaborate with a developmental company?
Bring on board a Non-Disclosure Agreement (NDA) prior to sharing information. Contracts need to state that you are the owner of all intellectual property and code, work with reputable firms with established history, and consider provisional patenting of truly new inventions.
