Hand Tremor Tracker vs. Tremor Monitor Utilizzo e statistiche

Hand Tremor Tracker is the most accurate hand tremor measurement tool available on the App Store. The application uses sensitive built-in device sensors to measure fluctuations of the device in three-dimensional axes. When the user holds their phone on top of their hand, the fluctuations of the holding hand become fluctuations of the device, allowing us to measure current hand tremor. See the references at the end of the description for more information. How to use: 1) Place your phone on top of your hand. 2) Tap the measure button to initiate a new measurement. 3) The application takes about 10 seconds to measure your current hand tremor. The application requires a paid subscription. A free trial is available. Subscriptions are automatically renewed and can be canceled at any time. Upon purchase of a subscription, Apple's Terms of Service and Privacy Policy apply: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Consider seeking a doctor’s advice in addition to using this app and before making any medical decisions.
