Reviews

Honest reviews

This site is built around a promise: no hype. So when people started asking us about heavily marketed focus products, we did the only thing that fits — we reviewed them honestly. What the sales page claims, what is actually verifiable, and whether it's worth your money.

How these pages work: every review here is an independent review — we are not the official site of any product we cover, and we haven't been asked or paid to write anything. The review pages may contain ClickBank affiliate links; if you buy through one, we may be compensated at no extra cost to you. That never changes what we write. The honest version is the whole point.

Before you buy anything

The products we review are audio programs. You can find out how frequency-layered focus audio feels to you right now, for free: our focus tool runs a 40 Hz-style session in your browser — one task, one timer, one steady sound, no account. It won't tell you whether a paid program is worth it, but it will tell you whether this kind of sound helps you at all. That's worth knowing before spending anything.

If you already know you want engineered focus music and would rather have a full app than a single audio program, the one we point people to is Brain.fm — 30-day free trial. (Affiliate link; if you subscribe, we may earn a commission at no extra cost to you.)

Research on gamma-frequency audio is early and mixed; we say so on every page where it matters. None of this is medical advice.
