I would have no idea how to use this or how to get one the AlphaOBD
There are a few other less expensive options if you're only looking to change tire sizes for speedo accuracy but nothing as powerful as AlfaOBD software that only costs $50.
There will be other costs for an interface (Bluetooth or usb) and security bypass cable, regardless of which software solution you choose.
I prefer to use a Windows laptop for reliability when making changes to my truck but many others use an Android phone or tablet.
And I prefer a hardline USB interface for stability, reliability, speed, and safely when altering the operations of truck modules but many users prefer to spend more $ for a Bluetooth solution.
You might choose to save $20 on the cost of the software app, if you're satisfied with the limitations of the less useful app.
And, if you can't be bothered with a DIY solution, you can likely find a tire shop or aftermarket parts store that you can pay to make these changes.
When I fine tuned my wheel size using AlfaOBD, I tweaked the settings a few time for a precise adjustment. It was very easy to complete.
I appreciate accuracy for measurements and my speedo calibration and in today's world, doubt there are many stores that would make such an effort.
If you decide that you would prefer to make your own adjustments, there are many members here who can assist you in learning your preferred method.

BTW, I have no affiliation with AlfaOBD, only a happy user and fan.
