### 1/5 — Why -

*2024-02-10*

I’ve always wanted to be a vtuber and when I saw this game I thought I had a chance but this game led me too a sketchy website asking me for personal information and you weren’t even aloud to make your own avatar you had to use somebody else’s 👎

### 2/5 — Just a white screen

*2026-02-03*

I love the game but I can’t play it at all cuz when I go in the game all it did was just show a white screen. I tried waiting thinking it was loading but after 5 minutes of trying to play the game I was just stuck with a white screen. If you can please fix this bug I would really appreciate it.

### 3/5 — Am I only allowed to import animation or pose files?

*2025-08-20*

This app looked promising, but I don't know how to import an avatar without importing it as an already animated character. I can't take the animation off even by clicking delete keyframes, and when I press new clip there is no option to add a model shown anywhere.  I can only add one from motion list, but they already have animation. What do I do?

**Developer response:** Thank you very much for your review, and I sincerely apologize for the very late reply.
To add motions, please use the Motion Capture button on the TOP screen.
Additionally, FBX or BVH files can be imported into the app by saving them in the animations folder, or by using the My Assets site:

レビューをくださり誠にありがとうございます。お返事が大変遅くなり申し訳ございません。
TOP画面のモーションキャプチャボタンからモーションを追加していく手順になります。
また、FBXやBVHファイルなどはanimationsフォルダに保存するか、マイアセットサイトを使ってアプリにインポートすることができます。

### 3/5 — Toon filter

*2025-03-28, version 1.10.200*

I can’t seem to find the toon/anime filter, did you remove it? Please bring it back 🙏

### 3/5 — it’s a good app but…

*2024-03-10*

i was very hard to use for me. and it kept glitching over and over again. there was not a way you could change your avatar in the game. i was looking for a app to be a vtuber but this was not it for me sorry.

**Developer response:** Thank you very much for your review.

### 4/5 — 😍

*2024-03-12*

So I think it’s a good game but at the start I was really struggling with trying to make videos so then I figured it out on camera mode but my body is always twisting around and I don’t like that so that’s why I gave this a four star rating

**Developer response:** Thank you very much for your review.

### 4/5 — Cool app, but…

*2023-10-03*

This is a really good app, and I love that I’m able to pretty much make anything I want in it (though it took me a bit to figure out.)

However, I’ve received a network error while in the middle of making a clip and despite my efforts (restarting my internet, restarting my iPad, redownloading the app) I am unable to regain access to the app. If there’s anything I can do to fix this, let me know.

**Developer response:** Thank you very much for your review.
Sorry for the very late reply.

I think this error was an operational error on my part.
From now on, I will update carefully.

### 5/5 — BLENDER ON THE GO

*2025-09-16*

This app may be confusing at first like any other animation studio, but once you find where everything bg is, you can create awesome animations!

### 5/5 — Nice

*2025-07-15*

I really like this app, my only problem is that the “perfect sync” doesn’t work for custom characters

**Developer response:** Thank you very much for your review. I sincerely apologize for the very late reply.
In order to use Perfect Sync, the avatar itself needs to be compatible.
Please try converting it with a tool like this:

レビューをくださり誠にありがとうございます。お返事が大変遅くなり申し訳ございません。 
アバターにパーフェクトシンクの対応をする必要があります。こちらの様なツールで変換してお試しいただければと思います。
