CNS Tap Test vs HeartRate Broadcaster

As featured in the book Beyond Training by Ben Greenfield. As featured in the podcasts: - Harder to Kill Radio 026 - Ameer Rosic Optimal Health Show #58 - Ben Greenfield Fitness #263 CNS Tap Test is an adaptation of the Finger Tap Test (FTT) or Finger Oscillation Test (FOT) which is used to measure the status of the central nervous system (CNS), and is one of the most commonly used tests in neuropsychology, because of its simplicity and reliability, and because it generates relevant data about fine motor control, which is based on motor speed as well as kinesthetic and visual-motor ability. The application should be used on a regular basis to determine an athlete’s baseline. If the CNS Tap Test result is elevated it is suitable for a maximum effort or a heavy lifting day. If the CNS Tap Test result is lower than average it may indicate CNS fatigue and impending sickness, injury or over-training. Both hands should be tested on a regular basis in a consistent environment, typically every morning on waking. The procedure for testing is: - Rest hand palm down on the heel of the hand on a flat surface - Tapping is done with the index (pointing finger), and all other fingers remain on the flat surface - The timer starts with the first tap - When the timer expires no further taps will be accepted - The result can either be saved or discarded. Multiple samples can be saved per day. The resulting data can be graphed, emailed or managed from within CNS Tap Test. Using Swift Charts for improved accessibility and legibility.

HeartRate Broadcaster turns your iPhone into a standard Bluetooth heart rate monitor, fed by the sensors you already wear. Your Apple Watch and AirPods Pro 3 measure your heart rate continuously, but nothing else can read them. Training apps and bike computers expect a Bluetooth chest strap. HeartRate Broadcaster bridges the two: it reads live heart rate from your watch and AirPods, reconciles them into a single reading, and rebroadcasts it as a standard Bluetooth LE Heart Rate Service. Your training app sees an ordinary strap. TWO SENSORS, ONE NUMBER When the watch and AirPods both report, the app averages readings that agree and rejects the outlier when they disagree, preferring whichever is closer to the trend it has already seen. Head units only ever see one sensor. The Sensor Agreement row shows which sensors are live, how far apart they are, and which number went out — so you never have to take the app's word for it. GLANCEABLE WHILE YOU RIDE A Live Activity puts the current BPM, its source, and whether a head unit is actually subscribed on the Lock Screen and in the Dynamic Island. Picture in Picture keeps the number floating over your training app. On the watch, a one-second press locks the touch screen against a jersey sleeve or a grab at the bar tape; another press releases it. DIAGNOSTICS THAT TELL THE TRUTH Connected devices by identifier, frames sent per subscriber, live frame rate, the exact bytes of the last frame, and how long ago it went out. When something is not working, you can see which half of the link is at fault. A permissions screen shows every permission the app needs, what it is currently set to, and a direct link to change it. WHAT IT CANNOT DO Apple provides no API for a third-party app to read a Bluetooth chest strap or another phone's sensors, so this app cannot import one. It broadcasts over Bluetooth LE only — ANT+ is a separate radio that iPhones do not have. Works with MyWhoosh, Zwift, TrainerRoad, Wahoo, and Bluetooth-capable Garmin Edge units. Requires iOS 26 and, for the watch app, watchOS 11.
