詩吟トレーナー「吟トレ」 is an innovative app designed to replace traditional accompaniment equipment for Shigin practice. It offers features such as prelude settings, adjustable bottle counts, fine piece adjustments, three scales, and six tone options. Users can also benefit from volume control and a timer for precise measurement. Note that while the tones imitate traditional instruments, they serve more as a supplementary feature. Ensure compatibility and functionality upon purchase, with a return option available.
