The full software: fix everything in one click
A PC you think is well tuned can still hide a few issues. Here's the breakdown of the 24 points that were missing on this example PC.
Why 74 out of 100?
Each issue found takes points off the score; fixing everything gets you to 100. Here's the breakdown for this example.

2 improvement point(s) remain: some cannot be fixed from Windows (BIOS, hardware) and are detailed below.
Before: the software creator's starting state, rebuilt from his settings at the time (simulation), then scored by the software's real analyser. After: a real analysis of the same PC, scored by the same analyser (software 1.16). Results vary from PC to PC; no FPS gain is promised.
Tools from €1.99 a month, Full at €11.99
No commitment. 8 tools (4 available today, 4 coming), from €1.99 to €2.99 a month for the available tools; the fuller your toolkit, the cheaper it gets (packs: Essential €5.39, Gamer €9.99, Streamer €9.29, Full €11.99); yearly = pay 10 months for 12.
Staying at 100 takes upkeep
Not at 100 yet? No problem: what matters is getting as close as you can. And even a PC at 100 can lose several points within a few days.
The software helps you keep it as clean as possible, with a reminder when your score drops or by launching just the tool that fixes your issue.

One piece of software, nothing hidden
Cleaners, driver updaters, FPS boosters: people often install several tools that promise miracles and do more than they let on. Here, a single piece of software explains every setting, makes it reversible (with a restore point created first) and tells you exactly what it keeps.
In full transparency
If you accept the terms on first launch, a copy of your report (PC model, components, settings, score) is kept on our servers. It is used to show your private page and to improve the software.
Your report contains no name or address; it's tied to a stable PC code (a pseudonym), not to your identity. We don't collect your files or passwords. You can ask for your data to be deleted at any time.
Privacy policyWindows shows a warning?
That's normal for new software that few people have downloaded yet. Click “More info”, then “Run anyway”. The official file is about 80 MB; its sha256 fingerprint is published in /downloads/latest.json.

Picture two PCs identical to yours: one badly tuned, one very well tuned. By comparing thousands of reports, we want to be able to recommend the settings that really work for your setup, without you having to hunt for them.
It works like a survey: the more reports there are (with no name or address), the more accurate the advice can be for everyone.
You stay in control: sharing usage statistics is on by default and can be turned off at any time in the software, and you can ask for your report to be deleted at any time.
