Roblox Studio is the utility tool to create Roblox games yourself. This article is the most important article to understand if Roblox Studio is officially available for iPad.
Way of using Roblox Studio on iPad
Roblox Studio is not officiallty available on iPad & you can not install the software on your Apple iPad model. If you see any website or article claiming that they can help you install it, then it could be a possible scam.
I could have written a well elaborated article stating so many links just to get the audience traffic on my website, but then that is really stupid way to be on internet.
Anyways, still if you want to use the Roblox Studio on your iPad, you can install the Chrome Desktop app on your device and use the remote Desktop to control your PC with the Roblox Studio installed. There is no other way apart from this.
