The startup team faced major challenges from the start, requiring the expertise of dedicated teams to address the following:

Cross-platform development: Ensuring consistent performance and user experience across iOS and Android platforms

React Native updates: Managing the complexity of updating to new versions of React Native and addressing compatibility issues with native modules to stay up to date on their launch

Accessibility support: Implementing comprehensive accessibility features to cater to users with visual, auditory, and other impairments, as required by US legislation

Chat functionality: Overcoming initial challenges to deliver a fully functional and user-friendly chat feature



Our team tackled the challenges head-on by leveraging their expertise in React Native and native iOS and Android app development.

We implemented a robust cross-platform architecture that ensures seamless performance across devices. The team also developed a streamlined process for managing React Native updates, minimizing compatibility issues and reducing development time. Based on our extensive experience, we determined the main patterns and flows that allow experts to fix the most common errors while maintaining well-functioning versions on both platforms.

To address accessibility requirements, the team worked closely with the product team to implement comprehensive accessibility features, including text-to-speech, gesture-based navigation, and compatibility with assistive technologies. We optimized the app's components to provide a smooth experience for users with disabilities, adopting a custom approach to development for each component on both platforms.

The team integrated a secure payment system using a third-party service that enables users to add bank accounts and withdraw funds safely and with equal speed on both platforms.

We also overhauled the chat functionality, transforming it into a reliable and user-friendly feature that enhances user engagement.
