Add Web Support To An Existing Expo App

Understanding the Benefits of Adding Web Support to Your Existing Expo App

If you already have a mobile app built with Expo, adding web support can provide numerous benefits. Here are some reasons why adding web support is worth considering:

Reach a Wider Audience

By adding web support, you can make your app accessible to users who may not have access to a mobile device or prefer accessing your app on a bigger screen of a desktop or laptop computer. This can expand your user base and increase your app’s visibility.

Cost Savings

Building a new web app from scratch can be expensive. By leveraging your existing Expo app and adding web support, you can save time and money on development costs. Additionally, maintaining one codebase can reduce ongoing maintenance expenses.

Improved User Experience

A web app can provide users with a different experience compared to a mobile app. For example, some features may be better suited to desktop browsers and users can use keyboard shortcuts for faster navigation. By adding web support, you can improve the overall user experience.

Enhanced Marketing Opportunities

Having a web presence for your app can help improve your search engine optimization (SEO) and increase your app’s discoverability. By adding web support, you can also take advantage of social media marketing opportunities to promote your app and engage with users.

Adding web support to an existing Expo app offers numerous benefits that can help increase your user base and improve the overall user experience. It is a cost-effective way to expand your app’s presence without starting from scratch.
