As far as I know there is no computer random number generator. Computers just can not do it.
But if the software is good enough it will be virtually indistinguishable from actual dice rolling.
There is a "random" (not truly random but you will never notice) number generator built in to the hardware of a computer but even that requires a bit of software to make it even more random. And then a bit of software to convert it into simulated dice of your choosing.
The dice use a physics engine to move them around a virtual space in a manner that emulates the behaviour of real dice. The initial velocity (speed and direction) is determined by combining unique, local, not repeating values seeded from your system. For example; CPU percentage, number of apps running, device IDs, system clock etc. Some dice sets even have slightly different virtual weights and friction based on the materials their skins are portrayed as having.
All this combines to create virtual dice that function offline with a high degree of pseudo-randomness and a low degree of repeated initial state likely (the chance that the initial variables will be the same and thus produce the same random number). Even the number and type of dice you roll will increase the randomness.
1. You can't predict a result. If you can tell that the die will be a certain value next time or know it's more likely to be a given value, then you have a problem.
2. It doesn't favour specific values to meaningful degree. If it rolls 1s twice as often as other numbers, you have a problem. If the variance is only a couple of percent, then it doesn't matter.
Whether a die is truly random or only pseudorandom is purely academic. You can even a fixed order of numbers, so long as you don't know which number is coming next when making decisions and it's not going to be substantially more likely to be some numbers than others. Iirc, Beyond has an issue on small screens where the dice don't have enough space to roll properly which can bias results, but otherwise it's perfectly fine for D&D.

If you're not willing or able to to discuss in good faith, then don't be surprised if I don't respond, there are better things in life for me to do than humour you. This signature is that response.
I still really wish they could add a feature to the app where you could shake your phone to send the dice tumbling.
(Not for actual game application but because it would fascinate me for longer than it should.)
I believe that's a feature on the android version of the app. It's not on the iOS version due to how iOS exposes the gyroscope to apps
No, it's not. At least not that I can see in the settings on the app and I can't seem to get it to work.

Shame. One of those useless but fun features that could swing me to using the app more.

Can someone explain how the virtual dice used by Beyond are as random as real world dice?
They are psedo random and will never will be truly random.

To be honest, only two things matter:
1. You can't predict a result. If you can tell that the die will be a certain value next time or know it's more likely to be a given value, then you have a problem.
2. It doesn't favour specific values to meaningful degree. If it rolls 1s twice as often as other numbers, you have a problem. If the variance is only a couple of percent, then it doesn't matter.

They just are its to basically make it fear both in app and on table

You're right, I think the feature was removed or maybe was on the previous app

To know it once existed and is now lost is almost worse, hopefully they re-add it someday. :O
