I can't do a full combo... I want to improve my score... I can't get the All Perfect... If you're like this, you need to train! This app specializes in training sound games with video. You can do the things you need to do to improve your score: memorize the chart, memorize the rhythm, and think about how to move your fingers. For example, to practice, you can do the following - Play the video at "slow speed" to see where you missed it. - Play full combo videos that others have uploaded to YouTube and learn the rhythm by touching the judging line. It's a video, so you can play it over and over again to review. Try to stay calm and review the difficult parts one at a time. Keep practicing the videos "at low speed" and "only the difficult parts over and over again" and you'll be able to improve your skills! ______________________________ MAIN FUNCTIONS - Play video in "Camera Roll", "iCloud Drive", "Transfer from iTunes", "YouTube". - Touching the screen during video playback will not pause the video. - Adjust the start/end position of video playback. - Zoom in or out on the video. - Adjust the video playback position. - Set the video playback speed from 0.25 to 2.00 times. - Set an area of the video playback. - Flip the video from left to right. - Support portrait and landscape video orientation. - Display the tap position line for some applications. - Easily rewind and fast forward during playback. What this app doesn't do - Video playback is not included.
