App development companies design, build and maintain mobile apps for iOS, Android and cross-platform frameworks. The eight below range from enterprise agencies to affordable studios, and the right pick depends on budget, complexity and whether you need design, backend and long-term support or just build work.
Pricing is usually project-based or hourly, with most agencies quoting after a discovery call. Prices below are marked "See website" since agency rates vary by scope and region. Ask for a fixed-scope proposal, a timeline with milestones, and ownership terms for code and accounts before committing.

How we chose
We compared agencies on their published portfolios, services, client industries and public reviews from clients. We favoured agencies with shipped apps, clear service coverage and a track record in their price band, from enterprise to budget. Prices were marked "See website" because agency pricing is quoted per project. We did not claim hands-on testing.
Vetting an agency before you sign
Check three things before committing. First, the portfolio: download the agency's shipped apps, use them, and confirm the agency really built them, since some portfolios exaggerate. Second, references: speak to two past clients about delivery, communication and post-launch support, not just the sales contact. Third, the proposal: a fixed scope, milestone timeline, code ownership and app store account ownership in writing.
Also clarify maintenance. Apps need updates for new OS versions, security fixes and store policy changes, so agree on a support plan and hourly rate before launch. An agency that disappears after launch leaves you with an app that decays within a year, so post-launch support matters as much as the build.
An app project needs a clear definition of done before development starts. Write down the exact features for version one, the platforms it must support, the performance targets, and the acceptance tests that prove each feature works, then get the agency to price that scope in writing. Resist adding features mid-build, since each addition delays launch and breaks the budget, and instead keep a version-two list for ideas that arrive during development. Plan the launch early: app store accounts, privacy policy, screenshots, descriptions and a review strategy all take time, and teams that leave them to launch week delay by weeks. Budget for the first three months after launch, covering bug fixes, OS updates and user feedback, because version one is a starting point, not a finished product.
App store optimisation should start before launch, not after. Research the keywords users actually search for your app's purpose, and write the title, subtitle and description around them, since store search drives most organic installs. Prepare screenshots that show the app's main benefit in the first image, because most browsers never swipe past it, and localise the listing for your launch markets rather than shipping English everywhere. Plan a review strategy for launch week, asking early users for honest reviews, since rating count and average shape store ranking. An app with a polished listing and early reviews outranks a better app with a neglected store page. Refresh screenshots and description with each major update, so the listing always shows the current app rather than launch-day screens.
Frequently asked questions
What is the best app development company?
Intellectsoft and WillowTree suit enterprises that want full-service development with strong design and engineering. Fueled suits design-led startups, while Appinventiv and Konstant suit businesses that want strong development at accessible prices. The best agency depends on budget, complexity and design needs.
How much does it cost to develop an app?
Costs vary widely by scope, from a few thousand dollars for a simple app to hundreds of thousands for a complex enterprise app. Most agencies quote after a discovery call, with pricing by project or hourly rate. Get a fixed-scope proposal with milestones before committing.
Should I choose native or cross-platform development?
Native development gives the best performance and platform features for iOS and Android separately, while cross-platform frameworks like Flutter or React Native share code and cost less. Simple and mid-complexity apps suit cross-platform well, while performance-critical or deeply native apps suit native builds.
How long does app development take?
A simple app takes a few months, while a complex app with backends, integrations and design takes six months or more. Discovery, design, development, testing and store review all add time. Ask the agency for a milestone timeline, not just a single launch date.
Who owns the code and app store accounts?
You should, in writing. Confirm code ownership, repository access and app store account ownership in the contract before work starts. Agencies should hand over source code, documentation and credentials at launch, with a support plan for updates.
Do app development companies provide maintenance?
Most do, through support plans covering OS updates, bug fixes, security patches and small features. Agree on maintenance terms and rates before launch, since an unmaintained app breaks as operating systems and store policies change.
