Cross-Platform App Development Company Hiring Guide
What is a cross-platform app development company?
A cross-platform app development company is a company that offers a seamless approach to mobile app creation. It goes beyond the traditional method of building separate apps for iOS and Android, opting instead for a single codebase that utilizes cross-platform frameworks like React Native or Flutter.
Businesses look for cross-platform mobile app development services because of these challenges:
Low or declining brand visibility and sales
App development using two code bases is slow and inefficient
Updates are limited and slow to deploy
Costly maintenance fees
Limited app functionalities and features
With cross-platform app development companies, businesses can experience faster development times and potentially lower costs. Their framework experts ensure the app functions flawlessly on both iOS and Android devices, creating a flexible app that can reach a wider audience without the burden of maintaining separate codebases.
Success story
In the following success story chosen by our experts, we highlight how a cross-platform mobile app development company improves business efficiencies:
Challenges: An American video rental company needed to upgrade its existing mobile app that was built with outdated coding practices, faced performance issues, and lacked device and orientation optimization. Its user interface (UI) was not intuitive, and it failed to load on a variety of devices.
Solutions: Simpalm refactored the codebase, improving app performance and ensuring smooth operation on modern devices. Its new intuitive UI was now optimized for various devices and orientations. The team also integrated a proprietary AI engine alongside an off-the-shelf solution to create recommendation algorithms. These algorithms learn user behavior and suggest relevant content and deals, driving higher in-app purchases and monetization.
Results: The collaboration improved the client’s mobile app. This resulted in increased user engagement, higher in-app purchases, and greater monetization for the client.

Success story
Cross-app development companies go beyond creating a seamless user experience (UX), as presented in the case study of Evolus and its partnership with Kingsmen Digital Ventures in creating an engaging app experience:
