SwitchedOn is a leading reaction training app that improves reaction time, agility, and decision-making through interactive cognitive-motor training drills. By combining brain challenges with real physical movement, SwitchedOn helps athletes, coaches, therapists, and active individuals develop faster information processing and more efficient physical reactions. With SO Vision AI motion detection, SwitchedOn can automatically measure reaction time and movement speed using your device’s camera, turning your smartphone into a powerful reaction time test and training tool.

HOW IT WORKS SwitchedOn uses randomized visual and audio stimuli (colors, numbers, arrows, etc.) to deliver powerful game-like reaction training drills. When a stimulus appears on your device, you react with real physical movement such as sprinting, shuffling, jumping, or touching targets. This trains your brain and body simultaneously, helping improve reaction time, agility, coordination, and decision-making in sports, fitness, and real-world situations.

This app is intended as a companion app for users with an existing King-Devick account. The King-Devick Remote App may be used to remotely administer the King-Devick Test in association with Mayo Clinic Concussion Screening Test and other King-Devick products such as King-Devick Pro Monitoring. The King-Devick Test in association with Mayo Clinic is an objective, remove-from-play sideline concussion screening test which can be administered by parents, coaches, athletic trainers or medical professionals in minutes. Peer reviewed published research has shown that the King-Devick Test in association with Mayo Clinic is an accurate and reliable method to help identify athletes with concussion on the sidelines. Peer reviewed published articles have also shown that King-Devick Test can be an effective tool in monitoring that progression of disease in chronic neurodegenerative diseases such as Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, migraine, Huntington’s disease, hypoxia, age related macular degeneration and other chronic neurodegenerative diseases.

Verdict
The clearest difference is in-app purchases: King at none against SwitchedOn's 8. King also leads on rating (5.0 vs 4.8) and iOS requirement (9.0 vs 15.5). SwitchedOn's advantage is update cadence (every 10 days vs every 8 months) and ratings volume (329 vs 1). On price, ads and device support there is nothing between them.
