Questions

Do I need an account for the free tools?

No. All free tools work without signing up. Just open the page and start calculating.

What does the Workstation include that free doesn't?

The Workstation adds finite element modeling for any room shape (not just rectangles), auto-optimized speaker placement, room measurement with a microphone, the full materials library, and a combined analysis dashboard.

Can I cancel anytime?

Yes. Cancel from your account page and you'll keep access through the end of your billing period. No contracts, no cancellation fees.

Is REW free? Why would I pay for Atuund?

REW is excellent and free. Atuund is different: it works from room dimensions alone (no mic needed for modeling), runs in your browser (no install), and auto-optimizes speaker placement. If you already use REW, Atuund complements it by finding optimal positions before you measure.

What happens to my data if I cancel?

All analysis runs in your browser. We don't store your room data on our servers. Your projects are saved locally and remain accessible even without a subscription.
