The content and update frequency are the same for both. There is currently no particular difference. Please choose the one you prefer. If you are having trouble, Booth is the way to go. I think there is a possibility that the update frequency will slow down.

Now, the only difference between the free version and the paid version is the following two points. The other functions are the same.
・In the free version, the startup page opens when you start the program.
・In the free version, the logo is displayed in the lower right corner of the screen when playing.

At the moment, there is only one model that can be loaded.
We plan to increase the number of models, save and load them in future updates.
The timing of the next update is yet to be determined.

In the case of booth, you can re-download from purchased items.
In the case of pixivFanbox, you can re-download from past posts.
In addition, the release of this software may be suspended depending on circumstances. Please understand this in advance.
