It’s fine but some issues

A friend was making a 3D model of me yes? So in order to calm myself down I got this app to get used to things, day 1 was awesome the tracking was on point and the mouth movement was okay in my opinion but day 2? Well the camera was shaking, the character was having a hard time following my eye movement and mouth movement, and it didn’t move at all. And sometimes when I opened the game the character wouldn’t respond to my movements it would just stand there starring at me so I got a little bit uncomfortable.. but yeah! It’s an okay game I just wish that I didn’t have bugged on my end 😅 thank you for taking the time to read this

A letter to the Devs as well as a few tips for those experiencing issues

Dear Developers,

Your app works great, and the facial recognition is seamless!

However, I hope this app will see some future updates and patches. The interface and software are quite intuitive, but there are still many dead ends (i.e. non-reversible actions) in the app that need fixing, such as:

1) Checking the option to hide the menu button leaves you with no way to access the menu again apart from reinstalling the app

2) Opening the menu using the aforementioned (unhidden) menu button leaves you with a nice menu with two tabs, but no way to exit the menu after that, whether any changes are made. As of now, the only way to both exit the menu and keep your changes seems to be to exit and relaunch the app.

Apart from these two dead ends, I see absolutely nothing wrong with this app on the iOS platform. Also, before posting a nasty review that the app doesn’t work, make sure to check if the software “works on this iPhone” because it requires both an iPhone/iPad with Face ID recognition, as well as the most up-to-date iOS version. Some older versions of iOS just don’t support face tracking/recognition even if the phone it is running on has the FaceID capability.

A humble customer and vtuber.

Miscommunication with the companion app

The app works fine on iPad Pro 2020 (with full face and head tracking) but ad far as I can see it isn’t sending informations correctly towards the pc app (Windows 10) since the model there is always T-posing. I’ve checked the IP and the port number, am I missing something?
