Controller Lab — Professional Gamepad Diagnostic Tool for iOS
This is NOT a game emulator or ROM player. Controller Lab is a standalone utility built for iOS gamers who want to test, calibrate, and optimize their Bluetooth game controllers.
Whether your stick drifts, a button sticks, or you want to fine-tune dead zones before your next session, Controller Lab gives you clear, measurable answers—right on your iPhone or iPad.
SUPPORTED CONTROLLERS
• Xbox Wireless Controller (Xbox One / Series)
• PlayStation DualSense & DualShock 4
• Nintendo Switch Pro Controller
• MFi-certified Bluetooth gamepads
• Siri Remote & micro gamepad (fallback)
KEY FEATURES
Dashboard
See connection status, battery level, Bluetooth info, and switch between multiple connected controllers. Built-in pairing guide helps you connect your pad step by step.
Button Tester
Visual controller skin shows every button press in real time. Monitor trigger pressure (raw and processed values), view an event log, and measure app-layer input latency (average and p99).
Stick Lab — Dead Zone & Drift Analysis
• Live dual-stick canvas with dead zone sliders
• 10-second quick drift check
• 30-second full drift report with health score, standard deviation, and 16×16 heatmap
• Shareable diagnostic report for troubleshooting or repair reference
Rumble Lab
Test left and right motors independently. Try preset haptic patterns, adjust intensity, and control DualSense light bar colors.
Game Profiles
Save per-game configurations including stick dead zones, trigger dead zones, and haptic presets. Apply profiles instantly, duplicate, edit, or back up your settings.
WHY CONTROLLER LAB?
Unlike basic button testers, Controller Lab combines drift diagnosis, latency measurement, haptic testing, and profile management in one focused tool—designed specifically for the iOS GameController framework.
No games are emulated. No ROMs are loaded. No copyrighted game content is involved. The app only reads input from connected controllers and helps you understand their behavior.
REQUIREMENTS
• iOS 18 or later
• A Bluetooth game controller paired via system Settings
