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.

Verdict

The call

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.
