Comments on OKN Drum Pro for Android

★★☆☆☆ mrted · Oct 31, 2024

Some functions do not work. Cannot adjust the lines except for display speed. Cannot adjust width.

★★☆☆☆ Janice Tanumihardja · Jul 17, 2024

Very laggy if sped up, pretty much unusable. I suggest aside from fixing the bagginess, please add a feature to rotate the stripes.

★☆☆☆☆ Nenad Mandić · Jul 15, 2024

Design is terrible, barely usable if even usable It's just mixing up colors, and I can't get good enough decades to use in clinical practice

★☆☆☆☆ Carlos Alfonso Rivera Maldonado · May 18, 2026

The giroscope is not working properly. I cannot choose the speed
