OKN Drum Pro

OKN Drum Pro appears to be a medical training and demonstration app centered on an optokinetic nystagmus drum. Based on the metadata, it may be used by healthcare professionals to support optokinetic testing or supervised visual exercises, rather than as a general consumer utility. The app’s controls for stripe width, stripe speed, and stripe color suggest it is meant to let users adjust the visual stimulus for different clinical or educational settings.

The app also includes a metronome, which may help with timing during demonstrations or practice sessions. Since it is a phone app in the Medical category, it seems aimed at mobile use in professional contexts where a portable visual stimulus tool is useful. The USB storage permission may relate to saving or loading app data, while vibration control could support simple feedback or device interaction. The description also notes that it is intended as an educational tool and should not replace traditional methods or be used for self-diagnosis or treatment without professional guidance.
