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  • Challenges: An American video rental company needed to upgrade its existing mobile app that was built with outdated coding practices, faced performance issues, and lacked device and orientation optimization.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.

What do cross-platform app development companies do?

Cross-platform app development companies specialize in creating mobile apps that function seamlessly on both iOS and Android devices using a single codebase. Here’s a breakdown of their core services:

  • Feature implementation 
    Program the features and functionalities you envision for your app, ensuring a smooth user experience across both iOS and Android

  • Post-launch support and maintenance

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:

  • Challenges: Evolus, a performance beauty company, struggled to enter the self-pay aesthetic market. The industry already had too many established giants, but its traditional communication methods could not grab user attention. It partnered with Kingsmen Digital Ventures to address the need for a customer-centric approach in the market.
  • Solutions: Kingsmen Digital Ventures implemented a design and technologically driven approach to make Evolus stand out from the market. It prioritized user engagement and injected a playful, interactive tone throughout the user journey, along with fast-responding functionalities.
  • Results: Within two quarters, Evolus rose to the #3 spot in market share. The app’s functionality translated to their ability to ship products to 3,500 accounts within 90 days. It has also fostered a user base that became active brand ambassadors. The platform’s engaging user experience led to referrals, propelling Evolus’ growth.

How much do cross-platform mobile app development services cost?

Cross-platform mobile app development services cost between $10,000 to $60,000 depending on the complexity of the app. Factors such as design, functionality, features, team size, and location of the team also affects the price of the cross-platform app development.

Here is a cost breakdown of cross-platform development app:

  • Simple app development — $10,000 to over $30,000
    Basic features such as login, user profile, in-app purchases, search
  • Moderate app development — $25,000 to over $45,000 
    Average features with additional inclusions such as social log-in and geo-tracking
  • Advanced app development — $40,000 and above
    Complex features with longer timelines and custom design and system

On DesignRush, the top 50 cross-platform development companies charge an average of $46/hour. 10.5% of cross-platform mobile app development services accept projects with a budget of less than $1,000, catering to basic app development. On the other hand, 5.7% accept projects with a $50,000 minimum budget offering more complex services and features.

The team also utilized a robust tech stack that includes iOS SDK, Swift, PHP (Symfony), Docker, AWS, Apple Maps, and Yelp.
  • Results: The partnership with Diffco exceeded the client’s expectations from project management to its expertise in design and development.
