What services does a mobile app development company in the US provide?
The core services of US mobile app development companies include product strategy and discovery, UI/UX design, development, quality assurance and testing, app store deployment, and maintenance and support. Some companies also offer system integration, internet of things (IoT) development, and AI product development.
Which platforms do US mobile app development companies typically support?
Most US development companies support Android and iOS systems and cross-platform frameworks. Many also build cloud-connected backend platforms and tablet-specific, multi-device, and ecosystem-level experiences.
StatCounter reports that that iOS accounts for 59.56% of the American mobile market share, while Android is at 40.46%. As such, it’s valuable to develop mobile apps according to your target users.
How much does it cost to hire a US-based mobile app development company?
Mobile app development costs in the US are about $100-$200+ per hour or $15,000-$30,000 for basic projects. Apps that require more complex features and functionalities can reach $150,000-$500,000+ per project.
What factors most influence mobile app development pricing?
Mobile app development pricing is primarily driven by a combination of scope, technical complexity, and delivery requirements. The most influential factors include:
Platform choice, design requirements, feature set, and complexity
Integration, security, and compliance requirements
Timeline and delivery speed
How long does it typically take to develop a mobile app?
Mobile app development generally takes about 2-3 months for basic products and over 12 months for enterprise builds. Here’s a breakdown:
Simple apps: 2-3 months, which typically have limited features and integrations.
Mid-complexity apps: 3-6 months for custom UI/UX, backend, and third-party integrations.
Enterprise apps: 6-12+ months for advanced functionality, scalability requirements, and extensive testing.
Does a US-based mobile app company build iOS and Android separately?
Most no longer do. Cross-platform frameworks allow one team to ship both platforms from a single codebase, which reduces cost and keeps feature parity. Designli, based in Greenville, South Carolina, uses React Native as its default mobile stack for exactly that reason.
