Open In WhatsApp

Open In WhatsApp is an open-source Android app for opening a WhatsApp chat without first saving a phone number to the device’s contacts. It is intended for people who need to start a chat from a number that is not already stored in their address book. The app provides a direct way to prepare the chat link that WhatsApp uses to open the conversation.

Users can enter a phone number in Open In WhatsApp and use the app’s button to open the resulting chat in WhatsApp. They can also choose a person from their existing Contacts when that is more convenient. The app does not require permissions, and its basic process consists of opening the app, entering or selecting a number, and opening the chat in WhatsApp.

Open In WhatsApp is listed in the Internet & Browsers category because it connects a phone number with a WhatsApp chat-opening link and passes that link to the messaging app. Its open-source license allows the software to be used as an openly available Android application. The app is neither affiliated with nor endorsed by Meta Inc.

MirrorNest distributes the official build directly from its own storage rather than describing a separate modified edition. Before publishing it, MirrorNest scans the mirrored build for malware. This makes the listing suitable for Android users looking for the Open In WhatsApp download in a catalog organized by platform and category.
