### 3/5 — 便利だが、使いにくい。

*2026-09-13*

VOICEVOXの他に、UTAU音源が使えるということでインストールしました。

ミッションをこなしていけば、使える機能も増え、ボイスバンクを追加するためのポイントも少なくなる仕様なのはいいと思います。ただし、今後のために以下の点を改善点としてあげます。

・一度ファイルに名前を付けると後から変えられない。

・UTAU音源の中のフォルダ名が同じだと勝手に歌い手が統合されてしまう。

・音声を再生している途中で画面が何度も固まる。

・歌詞を入力しても一部の音声がドレミでしか歌わない。

今後のアップデートで改善して頂けると助かります。

### 4/5 — 像人一样的美味软件

*2026-08-28*

这个软件太美味了，十分好吃，非常建议多囤点，然后顺便把你的手机或者平板也吃掉

### 4/5 — 挺好

*2026-08-24*

就是语音合成和选因素有点瑕疵和麻烦

### 4/5 — 希望能把每天看广告领积分的次数搞多一点

*2026-08-21*

整体用着还可以吧，就是搞那个歌手说话的时候有点麻烦，然后其他都可以，就是希望能把每天看广告领积分的次数多搞一点

### 5/5 — It’s good

*2026-08-14, version 2.6.31*

It’s good but I have to watch ads 24/7 js for 1 point 😭🙏

### 5/5 — 嘿嘿

*2026-08-13*

好像很多人都以为调音高要付费诶，其实导入7个声库就行了，后面会有折扣的，导入一个只要3积分来着（），而且这个有bug，导入声库然后删除，再导入这个声库就会判定你导入了一个新声库（不确定还能不能行）(⁎⁍̴̛ᴗ⁍̴̛⁎) 不过导入声库的吸气声怎么有电音（悲） 嘿嘿，好玩，希望能越来越好(◐‿◑)﻿ 呃呃然后就是导入声库要先下载声库文件，然后压缩才能导入，导入声库是点最下面的一行的右边，会有一个界面，点界面的的最上面（也就是显示了歌姬的板块，进去以后点右上角的加号，导入utau就点有utau的一栏，再导入压缩过的声库文件就行（不知道表没表达清楚反正帮一个是一个吧(>^ω^<)）不发声一般是软件还在生成声音或者卡了。(⌒-⌒; )
会有人看到吗(;´༎ຶД༎ຶ`)

### 3/5 — 还行

*2026-08-13*

导入歌姬很好，就是需要看很多广告。软件自带的歌姬完全唱不了歌。还有有些日文看不懂，唱歌的时候老是卡怎么回事啊！

### 5/5 — It’s good

*2026-08-12, version 2.6.30*

I like this but, the English words won’t work with my Kasane Teto download,Can you fix that?

### 4/5 — I’m really excited

*2026-08-11*

I’m so excited that a mobile app for this even exists. I haven’t gotten to play around with it much (because I’m scared, I’ve never made music in my life) but I really like it! My only wish is that you could go into the settings and reactivate tutorials if you missed something 

 edit: I think my one criticism is making it so all sound bites can only be cropped to whole notes, being able to make them half/quarter notes would be fantastic

edit 2: it lags a lot if your thing is a minute or two :( I tried to import a file to make a song with and was blasted with LAG

### 5/5 — 不错

*2026-08-09*

没有电脑也能用

### 4/5 — Pretty good app with a few bugs

*2026-08-09, version 2.6.27*

I love using this app but I have trouble importing UST files from my files app when I click the import button I have to watch an ad and when the ads over nothing happens I don’t know if I’m just doing something wrong but overall this is a pretty good replacement if you don’t have a computer

### 5/5 — 좋네영

*2026-08-08*

모바일로 조교를 할 수 있는 유일한 한줄기 빛 정도?
즌다몬은 기본으로 있고 테토 같은 우타우 음원은 광고 보고 포인트 있어야 가져올 수 있긴 하지만 이 정도면 ㄱㅊ
단점은 스냅이 1/16일 때의 노트 한 개는 길이가 너무 짧아서 길이를 늘리려면 1/8로 조정한 다음에 다시 1/16으로 돌아와야 하지만 그거 왜에 불편한건 딱히 없으니 강추 조작법도 쉬움요

### 5/5 — dude this actually rocks

*2026-08-07, version 2.6.27*

wdym i can use utau and cevio voicebanks for free omg

### 4/5 — emmmm整体还好

*2026-08-05*

很适合苹果妹的调音软件 但是除了自带的毛豆只要是导入的歌姬声音都会变沙哑 还有莫名的气声

### 5/5 — 짱

*2026-08-05*

가끔 소리가 안 나오긴 하는데 이제 한국어 노래도 부를 수 있어서 좋아요

### 5/5 — peak

*2026-08-03, version 2.6.25*

i finally was able to make a silly teto thing :D yeah its pretty awesome soo yuh :D although, the only thing thats kinda tiring is having to sound out words heh- otherwise its awesome

### 4/5 — 挺好的

*2026-08-01*

就是不知道为什么每次切换软件后就没声音了而且每次登又要一分钟

### 4/5 — It works

*2026-07-29, version 2.6.23*

Overall good, but if you don’t have premium, you will have to watch a lot of ads to get points.

### 5/5 — Great App

*2026-07-29, version 2.6.23*

super easy to use!	 it lets you upload a variety of voicebanks as well and is overall a great alternative to vocaloid editor or open utau!

### 5/5 — Vocaloid is peak

*2026-07-28, version 2.6.22*

Yes i like it

## Most critical reviews (10 lowest-rated)

### 1/5 — feels insanely money hungry

*2026-06-17, version 2.6.14*

i am a vocal synth user, i use synthv, voisona, voicevox and utau. this app feels very money hungry.
basic functions in vocal synth applications cost 10 dollars. while its cheap for a vocal synth software, a lot of people dont wanna pay. 
yes you can use the paid features tor free, but you have to watch ads. uploading a UTAU voicebank costs 10 points, which you have to watch over 7 ads for.
uploading a midi costs 1 point per track which results in you watching 1 or more ad.
the most basic function of tuning is also behind a paywall.
i would never recommend this app to anyone beginner or professional. the app feels insanely money hungry and its easier to use websites like utalet.

### 1/5 — Easy

*2026-06-08, version 2.6.14*

Really easy to use and tune!! I already downloaded teto!

### 1/5 — paywall

*2026-05-29, version 2.6.14*

paywall

### 1/5 — Can’t even type one lyric

*2026-02-20, version 2.3.12*

I can’t even tune one lyric without an error, not to mention no English option for non paid version. Why even try

### 1/5 — This is BUNS

*2026-02-06, version 2.3.9*

It’s a decent app but if u don’t pay for premium u could literally make the most beautiful note combination in history but as soon as u try to add lyrics you realize u cant have any lyrics above 3 letters.

### 1/5 — This is so pay to use

*2026-01-08, version 2.2.7*

I hate that i need to pay to use everything and it's barely in english

### 1/5 — Extremely hard to use

*2025-12-30, version 2.2.2*

Most of the instructions are in Japanese

### 1/5 — I am fairly dissatisfied

*2025-11-10, version 2.0.6*

I cannot find how to listen to what I say, there are too many ads, and it crashed on me multiple times. I am fairly disappointed

### 1/5 — It’s awesome!

*2025-11-02, version 2.0.4*

It’s so good

### 1/5 — i don’t understand a thing..

*2025-08-29, version 1.4.9*

this app makes no sense😞 i really wanna try and make a song with miku but i dont know how to get vocaloid on a computer so i thought this would work but no:( maybe it’s because i dont understand the japanese or something? i dont know

### 5/5 — This is really good

*2026-09-13*

Works pretty well, few bugs with voice generation where if you press the play button as it’s generating it will just not work anymore so you have to leave the project and reopen it, but otherwise pretty awesome. Oh, also, it was very generous to offer paid features only by watching ads and getting them forever. It’s just tedious, but I suppose it’s the price I have to pay to be able to use things.

### 5/5 — 很好用，新手推荐

*2026-09-08*

很好用呀，俊达萌有好多声线，满足了我们的需求，还可以导入声库，新手也能马上就熟练

### 5/5 — 优秀

*2026-08-31*

算是一个比较廉价的搞术力口的方式了，但是我目前没玩明白怎么去微操每一个音符的音量大小，还有就是得看点广告，这个问题不大。目前里面有免费自带的声库。

### 5/5 — 大好きなのです！

*2026-08-31*

MIDIファイルも読み込めるし、広告さえ見れば好きなモデルを読み込めるのです。UTAUがスマホでできるのはすごくいいので、愛用しているのです。だけど電池の減りが早いし、すぐ本体があつ〜くなるのです。まあしょうがないとは思うのです。あと、無料だとピッチの編集ができないのです。それが辛いのです🥲‎なんか条件付きでもいいので、無料で少しでもできるようになってくれると嬉しいのです！

### 5/5 — 好用_(:з」∠)_

*2026-08-27*

挺好用的一款软件，也是我第一次接触到的调音软件，之前是在抖音上看到有人推荐然后就下载了，毛豆很萌，有不同情绪的声库，用着确实不错很顺手，但是有的时候需要看广告，里面的广告有一点点多╮(╯_╰)╭。导入声库也可以，需要先看广告赚积分，之前下载了teto的声库也能导进去。也遇到了点问题，现在一共导入了三种音源，但是只能看到两种，不知道是什么原因求解答。（导入七次就可以画音高线了，开始以为是免费的。。）刚打开页面会有一点卡等两三分钟就好了，总体来说还是很推荐的

### 5/5 — Best Mobile UTAU Studio!

*2026-08-22*

This app is absolutely amazing! It has a few cons, but many pros. So, for the fully free version, you get to import an UTAU for 10 points (which you need to watch 10 ads for). You can’t tune the UTAU, which isn’t great, but it is still fun and is functional. For the Premium version, it’s the best. You can import as many UTAUs as you would like, and you can tune them! Plus, it’s only 1$ per month/10$ for full-time! I do have trouble adding growl to the UTAU’s voice, as the vibrato slider is sort of randomized. Other than that, it’s great. Definitely recommend the premium.

### 5/5 — 아니 버그고쳐줘요 좀

*2026-08-21*

아니 원래 모바일로 조교를 할수 있고에 굉장함을 느끼고 이것만으로도 즐겨야 겠다 했는데 버그 갓겜이라 뭐 어찌해야 할지 모르겠음. 현재 아이폰으로 사용하는 유저인데 앱 접속 할때마다 쿠키런 크럼블 광고소리만 계속 쳐나서 조교를 못하고 있어요; 애초에 조교하다가 앱 나가기만해도 멈추는 앱인데 계속 쿠키런 크럼블광고 소리만 귀에 쳐박아 넣으니까 노이로제만 계속 올거 같고 정신 나갈거 같고 와 진짜 이거 하나만 고쳐주세요 진심

### 5/5 — Best vocaloid alt!

*2026-08-17, version 2.6.31*

Works awesome!

### 5/5 — 非常好用

*2026-08-16*

非常好用，这个真的非常好用，还可以导入深库

### 5/5 — Greatttttttttttttttt

*2026-08-14, version 2.6.30*

So good
I’m so lost for words
