Frequently asked questions
What founders ask before hiring a mobile app development agency.
A mobile app development agency for startups designs, builds, and launches iOS and Android apps end to end — from product strategy and UX to native engineering, backend APIs, App Store release, and ongoing support. Appzay acts as your technical partner, handling the entire product so founders can stay focused on customers, growth, and fundraising.
Most funded startups go from idea to a launch-ready app in a matter of weeks, not months. We work in weekly sprints, so you see real, testable builds every week instead of waiting for one big reveal. The exact timeline depends on scope and integrations, which we lock down in the first strategy phase.
Engagements are scoped to your stage and goals rather than a fixed price list. Most projects run as a focused MVP build or an ongoing product partnership, and we give you a clear, milestone-based estimate before any work begins. The fastest way to get a number is a free consultation where we map your scope and budget together.
Yes. We build native iOS (Swift) and Android (Kotlin) apps, as well as cross-platform React Native products when that's the right fit — plus the backend, cloud infrastructure, and App Store delivery behind them. We recommend the approach that best balances performance, speed, and budget for your product.
