The speed training mode would be awesome if the top tempo didnt constantly (and randomly) default to 298 bpm while adjusting other parameters. Accuracy training mode also has terrific promise, but again the RH dial (total number of bars) cycles around randomly while setting other parameters. Sloppy, for a paid app. Sort out in next update and itll be 5 stars; right now, 3 stars is being generous.
