What's New in Metronaut

8.3.1

July 16, 2026

NEW Wait Mode: Perfect for sight-reading and learning new pieces. The score waits for you as you play, advancing note by note while giving you instant feedback on whether you played the correct pitches — now including piano! NEW: Continue practicing through a playlist or collection without quitting the sheet music screen. A “Next piece” button appears at the end of the score, letting you load the following piece or movement without leaving the practice screen. AI Feedback for Pianists: See exactly what you played right or wrong directly on the sheet music, and progress even faster — all in real time! Easier Sheet Music Annotation: Drag and move symbols to place them exactly where you want. Plus improved symbol rendering on iOS and macOS. Smaller and Faster: The app is now lighter and runs even faster. :)

小提琴不好用

可能好评都是钢琴给的？反正我小提琴觉得很难用。AI听音功能非常不智能，而且好歹给一两首试用呀！虽然有7天免费，但是一上来就让订阅，要是不取消之后就自动扣费了，这个行为就很让人反感。

您好，很抱歉给您带来困扰了。AI跟随功能最好需要连接耳机或者蓝牙音箱，能得到更好的效果哦，不然也可以将它关闭。关于订阅，我们提供七天试用，期间可以取消，如果打开App消息的话可以收到提醒。如果忘记取消被扣费了，可以向Apple申请退款。

差评

问题有很多，比如免费试用自动续费却没有短信通知提示，练琴的时候声音识别又不清楚，帮助和关于页面打不开等等

没有我需要的曲子

理想的软件，莫扎特，巴哈比较多，可惜其他就不一定有，还不够完美。所以还没交钱。
自动扣款的功能真要命。每次付款都要询问密码就好了。而且最后能月缴费，不要一来就一年

这个软件真的非常好用啊啊，需要的基本都有了，还会有伴奏，拉起来就特别舒服。我是拉中提琴的，找了很多软件都基本没有中提琴谱子，这里面选了乐器之后的谱子非常符合我想拉的，可以当作练练手。
