The exact split
The 192-tweak library is counted from the shipped app. Free reaches every category; PRO adds the deeper set. Tool access is listed separately so it does not inflate the tweak numbers.

Free
Free is not a countdown or a demo shell. It includes the core proof and recovery tools alongside 43 working tweaks.
The Download page currently shows when the verified installer link is available.
PRO
PRO adds the other 149 tweaks plus deeper controls. It is a one-time upgrade through Gumroad, not a recurring plan.
Gumroad emails your key; paste it into the app’s activation dialog.
Which one should I choose?
There is no wrong starting tier and no timer pushing the decision.
01
If you want to run your own benchmark, apply the free set, and learn how YUKFUE fits your PC before paying.
02
If you want the full 192-tweak library and the documented deeper controls in one one-time upgrade.
03
Start with Free. Use the benchmark and exact in-app comparison, then upgrade only if the additional library makes sense for you.
Proof before upgrade
The built-in benchmark compares your own before-and-after result and accounts for normal run-to-run variance. It does not promise the same gain on every PC.
See how the benchmark works →Restore Center
Original settings are saved before supported tweaks are applied so Restore Center can undo them. Rare actions that cannot be automatically restored are marked ONE-WAY before you choose.
