Mobile app development cost in Bangladesh depends mainly on feature complexity, whether the app needs a backend/database, and whether it's built cross-platform (e.g. Flutter, covering iOS and Android from one codebase) or natively for each platform. A simple single-purpose app costs far less than one with real-time features, payments, or admin dashboards.
App development cost scales almost entirely with complexity, not with the idea itself. A simple informational app with a handful of static screens costs a fraction of an app with user accounts, real-time data, payment processing, and an admin dashboard for the business side. Before getting quotes, it helps to have a clear feature list rather than a general concept — vague requirements lead to vague, hard-to-compare pricing.
Flutter allows a single codebase to run on both iOS and Android, which typically reduces development cost and time compared to building two separate native apps. Native development (separate Swift/Kotlin codebases) can offer marginal performance advantages for certain graphics-heavy or hardware-intensive apps, but for most business apps — e-commerce, service booking, internal tools — Flutter's cross-platform efficiency makes it the more cost-effective choice without a meaningful trade-off in user experience.
Real-time features (live tracking, chat, live order status), payment gateway integration, complex backend logic, third-party API integrations, and admin/business-side dashboards are the features that most significantly increase development time and cost. A simple app with none of these can be built and shipped considerably faster and cheaper than one that needs all of them working together reliably.
Ask whether the quote includes backend/API development or only the front-end app, whether app store submission and approval support is included, what post-launch support and bug-fix terms look like, and who owns the source code once the project is delivered. These questions matter more for comparing quotes fairly than the headline number alone.

Native and cross-platform apps for iOS and Android
Generally yes for most business apps — Flutter's single codebase for iOS and Android typically reduces development time and cost compared to building and maintaining two separate native apps.
Real-time features, payment integration, complex backend logic, and admin dashboards are the features that most significantly increase development cost and time.
