Frequently asked questions
Quick answers about how this directory works, before you download anything.
Yes — every tool listed here is free to download. A few offer an optional Pro upgrade for advanced features, and that's always noted clearly on the tool's own page before you download.
Every tool is tested for what it actually does to system latency before it earns a spot — not just whether it claims to fix something. We check real-world behavior, not just marketing.
Every listing shows a safety status (Clean or Caution) based on how it was tested. We'd rather flag a tool honestly than hide a concern to keep the list looking longer.
New tools and version updates are added regularly as we test them. Check back on the homepage to see what's new, or use the category filters to browse by type.
