## Description

**Crono** brings your mobile notifications directly to your browser, keeping you seamlessly connected whether you're in meetings or multitasking between tabs. It mirrors your phone alerts, enabling you to receive push notifications, clear alerts from both devices simultaneously, dismiss calls, and send instant SMS replies right from your desktop.

Enjoy blazing fast responses with one-click replies across popular chat and email apps like WhatsApp, Messenger, Hike, and Gmail. Your notifications remain secure through end-to-end encryption with offline key sharing via QR codes, and you can quickly hide sensitive data with a simple click. Additional features include clipboard sharing between your device and browser, and a convenient "Find your phone" function that rings your phone from the browser for easy retrieval.
