I love this app. being able to use words makes this app very useful. back, front, left, right, up, down, etc. plus being able to set the maximum and minimum time between the random commands is the best. very useful for a reaction box drill.

Firstly the visuals have improved, making the appearance, experience very interactive and entertaining. The Playlist has been maintained and the audio has also improved from the previous version, it is giving a more crispy clear sound👌🏼 It is easy to work around for my daily routines and sessions, enabling me to my solo workouts lol, it's effect as much for group settings. Looking forward to more animated visuals that demonstrate the actions with the Playlist💯 PS keep up the good works

Great app. Been looking for something like this. It could do some improvements tho. I suggest the playlist tab be added with folders so we can organize recorded voice clips according to the type of workout. For me I do boxing, HIIT and running and it's kind of a hasle scrolling and looking for that particular clip every time I change workouts. Cheers guys!
