Open In WhatsApp1.5

Enter a phone number in Open In WhatsApp and it creates a direct link for opening a conversation in WhatsApp, without first adding that number to the device’s contacts. This solves the small but common problem of starting a one-off chat with a customer, delivery driver, service provider, or other unfamiliar contact. When a saved contact is more convenient, you can select a person from the phone’s existing Contacts instead.

The app passes the generated chat link to WhatsApp so the conversation can open there directly. Its everyday process is limited to opening the app, entering or choosing a number, and tapping the button that opens the chat. Open In WhatsApp does not require permissions, keeping the number-entry workflow focused on the requested chat.

Open In WhatsApp is an open-source app for Android 5.0 and later, with Universal architecture. It suits Android users who regularly message unsaved numbers or want a quick way to turn a phone number into a WhatsApp chat link, and it is neither affiliated with nor endorsed by Meta Inc.

Version 1.5 fixes a dark-theme issue and applies more liberal phone-number validation. It also removes unused libraries and enables minification to reduce the APK size.
