WizzyPoke

WizzyPoke is a browser extension that lets you send subtle screen shake to get someone’s attention when they miss your message. After pairing with a simple 6-digit code, you can send a nudge that triggers a vibration style screen shake with sound, even if they’re on another tab or website. Works across all tabs from messaging apps to video sites without accounts or logins. The free version includes limited daily nudges, with an optional premium upgrade for unlimited use.
