The actual interface, rebuilt in your browser with real stereo audio. Headphones on, press play: a classical guitar in your left ear, an audiobook in your right. Drag a card to move it, or tap it to cycle L → R → both.

Full app, free for 10 listening hours. No account, no card.
The moment Stripe confirms your payment, our license server signs a key for your email and sends it. Paste it into the app's unlock screen, it activates in a second, and from then on it verifies offline.
You get the licence now for $0 and post about the app from your own TikTok, Instagram or YouTube account within 7 days, with an #ad disclosure. Looky reads the post's views and any sales it refers through your own account and works off the $1.99. Keep the post live for 30 days. If it falls short, only the unearned part, never more than $1.99, is charged to the card you saved. Delete the post early and the full $1.99 is due after a 72-hour grace period. No interest, no instalments.
Once — when you first paste your key, the app registers this machine with the license server and stores a signed proof locally. From then on everything verifies offline. No account, no analytics, and your audio never leaves your machine — we only route it.
Yes — one payment, no subscription, no renewal. Personal covers 2 machines, Business covers 5. Reinstalls on the same machine never use an extra slot, and support can move a slot if you replace hardware.
Linux does true downmix-to-ear and per-browser-window routing. Windows routes whole apps per ear via native session channels; hard-panned stereo keeps only the chosen side's channel. For speech and most music you won't notice.
If it doesn't work on your setup within 14 days, reply to your receipt email and we'll refund you. The 10-hour trial exists so you rarely have to.
