tremor - haptic tester is a free utility mobile application by developer vadiole, and is a tool to help users test the haptic motor built into their devices and see if they are working properly. It provides a wide variety of testing parameters to cater to different triggers and scenarios. 

Feel the vibration 

In a word, tremor - haptic tester lets you see (or feel) if the haptic motor inside your mobile devices is working as it should. It’s built around constants, which you can view as scenarios or inputs that simulate things like a keyboard press, switch toggle, and the like. There are also built-in presets for the more common clicks and ticks referred to as primitives. 

No matter what you choose, you can customize various parameters that control vibration length, intensity, and effects as you want. Now, as intricate and personalized as this tool is, it’s more meant for app developers who want to integrate vibration APIs into their work. It has little to no real-world application or use for most average users. 

Intriguing but specialized 

To sum up, if you’re a developer working with vibration APIs on your app, tremor - haptic tester is an impressive tool to help you test it out using a wide variety of scenarios and conditions. On the flip side, it’s also just fun to play around with if you’re just curious about how well the haptics on your device perform. All the same, this is a great app to try out.
