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.

Measure, train and monitor strength with ForceDecks; the world’s fastest, easiest and most powerful dual plate system for analysing neuromuscular strength and imbalance. Traditionally, force plate software was only capable of collecting and displaying raw data, along with a few simple summary metrics, meaning any further analysis had to be done slowly and manually. With ForceDecks, all that heavy lifting is done for you – from detection to analysis and reporting. The ForceDecks App also allows you to: - Wirelessly collect data via Bluetooth on a range of movements. - Manage or add profiles. - Rapidly run through tests back-to-back. - Upload data to VALD Hub for analysis and comparison to historical results. Requirements : - Requires iOS 13 or later - Requires internet connection (additional fees may apply) - Requires ForceDecks hardware

Verdict
The clearest difference is price: ForceDecks at Free against CNS Tap Test's $1.99. ForceDecks also leads on update cadence (every 3 weeks vs every 3 months) and device support (3 vs 1). CNS Tap Test's advantage is ratings volume (277 vs 4) and chart position (#176 vs unranked). On rating, ads, in-app purchases and monetization model there is nothing between them.
