Agencies marked Verified have been checked against four things: that the business trades under the name given, that its contact details resolve to it, that the services claimed match demonstrable work, and that the stated minimum budget reflects real engagements. The others are listed from their own websites and have not been checked yet.
Listings are ordered by membership placement, then by OAN Score. Membership does not affect the score itself. Tier is not one of its inputs, so placement cannot buy a better number. Read the full method.

What is a Mobile App Development agency?
A mobile app development agency builds and ships software to the App Store and Google Play, which means it also inherits the store review processes, the release cadence and the long tail of devices. The build is rarely the hard part. What separates competent shops from the rest is what happens in the eighteen months afterwards: OS versions move, certificates expire, review policies change, and an app with no maintenance plan becomes unshippable long before it becomes unpopular.
What Mobile App Development agencies do
- Native iOS and Android development
- Cross-platform development in React Native or Flutter
- Backend, API and sync architecture
- Offline behaviour and conflict resolution
- Push notification strategy and infrastructure
- App store submission, review and release management
- In-app purchase and subscription implementation
- Crash reporting, analytics and performance monitoring
- Accessibility on both platforms
- Ongoing maintenance and OS upgrade cycles
What Mobile App Development costs
A first release commonly costs $50,000 to $300,000, with cross-platform builds typically landing lower than two native ones. Maintenance is the number most budgets miss: plan on roughly 15 to 20 per cent of the build cost each year simply to keep the app in the stores and working. Ask any candidate what their last three apps cost to maintain in year two. An agency that has never been asked will not have the figure, which is itself informative.
How to choose a Mobile App Development agency
The native-versus-cross-platform argument is usually presented as a technical one and is really a hiring and budget one. Cross-platform costs less to build and less to maintain, and gives up ground on heavy graphics, deep OS integration and being first to adopt a new platform feature. If your app is a well-designed interface over an API, cross-platform is very likely correct and an agency insisting otherwise should be asked to say specifically which feature requires it.
