Developing a mobile app that performs flawlessly in the real world requires thorough testing under a variety of network conditions. Introducing Flaker – your assistant tool for recreating real-world network scenarios directly in your mobile app development environment. 📱💡

## What is Flaker?
Flaker is a network simulator designed to make your mobile app development process smoother and more efficient. With Flaker, you can effortlessly emulate a wide range of network conditions, enabling you to fine-tune your app's performance and ensure it delivers an exceptional user experience under any circumstance. 🌐🛠️
