Hand Tremor Tracker vs Cognitive Shuffle

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.

Can't fall asleep? Your mind won't stop racing? Drift uses the science-backed Cognitive Shuffle method to help you fall asleep faster — no meditation, no breathing exercises, just words. How it works: Simply tap Start, close your eyes, and listen. Drift whispers random, unconnected words to your mind — breaking the cycle of anxious thoughts and guiding your brain into sleep. Based on research by cognitive scientist Dr. Luc Beaudoin, the Cognitive Shuffle technique mimics the natural thought patterns of sleep onset, helping your brain transition from wakefulness to rest. ◆ Zero setup — open and sleep ◆ 8 languages — English, Spanish, Portuguese, German, Russian, Chinese, Arabic, Turkish ◆ Alphabet mode — engage your mind gently ◆ Adjustable word speed — 4 to 15 seconds ◆ Auto sleep timer — 15, 30, or 60 minutes ◆ Fades out automatically when timer ends
