Why there is no single price for 'an app'
Two apps described in the same sentence can differ by months of work. 'A marketplace app' might be a listing feed with a contact button, or accounts, payments, messaging, reviews and an admin panel. Any price quoted before scope is either padded for safety or too low to deliver. That is why we estimate after discovery, from a written list of screens and features.
The seven cost drivers
| Driver | Why it matters | Cheaper option |
|---|---|---|
| Scope | Screens, user roles and workflows are the biggest factor | Cut to one core workflow for the first release |
| Backend | Accounts, sync, subscriptions and admin panels add server work | Offline-first where the product allows it; Firebase instead of custom infrastructure |
| Integrations | Payments, maps, third-party APIs and hardware each add build and test time | Start with the one integration the core job needs |
| Design | Fully custom, animated interfaces cost more than well-used Material components | A Flutter theme over standard components, customised where it counts |
| Platforms | Each store adds testing, setup and review even with shared code | Launch on one store first |
| Media and on-device processing | Image, video and ML work needs careful performance engineering | Use proven packages; process in background isolates |
| After launch | Maintenance, policy updates and new features continue | Plan a maintenance budget from the start |
How the ranges usually break down
Rather than quoting dollar figures that depend on region and team, it is more useful to think in effort tiers. A focused MVP with one workflow and no custom backend is the smallest tier. An app with accounts, a Firebase backend, push notifications and a subscription is a mid tier. A multi-role platform with an admin panel, complex integrations and both stores at launch is the largest tier, and often several times the MVP effort. Public market surveys place these tiers apart by an order of magnitude, which is why scope decisions matter more than rate negotiations.
What an honest estimate should include
- The features and screens in scope, and what is explicitly out of scope
- Technology choices: framework, local storage, backend and integrations
- A delivery plan with milestones and test builds you can install
- Store publishing work: listings, privacy policy, Data safety and review
- Assumptions about content, designs and accounts you will provide
- Options for maintenance after launch
How to lower the cost without lowering quality
- Write down the one job the app must do, and defer everything else
- Use Flutter so Android and iOS share one code base
- Choose Firebase over custom infrastructure for the first version
- Accept standard platform components for secondary screens
- Launch on one store first, then add the second
