Vibration Test
Test your smartphone's haptic feedback motor using standard or custom vibration patterns.
Enter comma-separated millisecond values. Odd indices (1st, 3rd) are vibration duration. Even indices (2nd, 4th) are pause duration.
Checking Your Device's Haptics
The vibration motor (or haptic engine) in your smartphone provides crucial tactile feedback for notifications, typing, and gaming. When a phone is dropped, the delicate moving parts inside the vibration motor can become jammed or disconnected. This tool lets you send raw signals directly to that motor to verify its health.
iOS and Apple Restrictions
Apple heavily restricts web browsers on iOS. Currently, the Web Vibration API is disabled in Safari and all other browsers on iPhones and iPads. If you are using an iOS device, this tool will not be able to trigger your vibration motor due to these intentional software limitations by Apple.
Using Custom Vibration Patterns
Our tool allows you to test both continuous vibrations and complex rhythmic patterns (like an SOS signal). By creating a custom pattern, you can test if your motor is responsive enough to handle rapid start-and-stop commands, which is essential for crisp, high-quality keyboard haptics.
