Native App Previews in Appflow streamline the process of testing native mobile apps by offering in-browser testing on iOS Simulator and Android Debug builds directly within the Appflow dashboard. This feature eliminates the need for complex software dependencies and device configurations, allowing developers to test apps on a variety of devices and operating systems without leaving the platform. The previews are accessible through a secure URL, facilitating collaboration between development, QA teams, and stakeholders, who can interact with the app in a simulator or emulator without additional installations. Appflow uses Appetize.io to enable virtual device testing, and users can customize device specifications and enable network and debug logging for detailed testing. Available on all paid Appflow plans, Native App Previews simplify the setup for cross-platform mobile developers by integrating seamlessly into their existing workflows.
