PerformanceX Insight

PerformanceX Insight is an advanced simulation toolkit for developers, QA testers, and tech enthusiasts. It features a RAM simulation tool to test app behavior under memory pressure, allowing you to simulate both instant and gradual RAM allocation with built-in safety limits capped at 65% of total RAM. The tool automatically releases memory when the system is under pressure to prevent ANR issues.

The app also includes a network simulation feature that can completely block internet access with one tap using a local VPN implementation, perfect for testing how your apps behave offline. A floating overlay control allows you to quickly toggle blocking on/off and can be dragged anywhere on screen. No data is routed through external servers - all blocking happens locally on your device.

It is also having a tool which will trickle the internet as connect and disconnect to check fluctuations during QA checks

Overlay permission required for floating controls, VPN permission required for network simulation, and notification permission optional for status updates.
