Top 100 Cross Platform App Development Companies
The Best of December 2025Looking for a top cross platform app developer?
Cross platform mobile applications support multiple mobile platforms or operating systems with a single codebase. Also referred to as hybrid apps, cross platform mobile apps are known to operate well both with iOS and Android operating systems. Developing a cross platform app may save you time and money if your audiences use both Android and Apple products. The alternative is developing separate apps for each operating system using the respective native technologies.
As you look for a cross-platform mobile app development company, ask about the team’s familiarity with React versus Ionic. Most hybrid apps require these development frameworks. If you’re unsure which framework is best for your business and app, a cross platform app developer should be familiar enough to lay out pros and cons and advise you on the best framework for your app.
That's why we've created this list of the best cross platform app development companies for you to review. Read through company descriptions, former clients, and notable projects to find the best fit for your business.
