WhatsTool for Bulk Messaging, developed by WhatsTool Tech, is a free Android utility that helps individuals and small businesses use WhatsApp for outreach. The app focuses on making it easy to compose a message once and deliver it to multiple recipients, saving the time required for repetitive manual sending.
After installing the app, you open it and grant the permissions it requests to access your contacts and WhatsApp. You then create a new campaign by selecting the recipients, writing or choosing a template, and optionally attaching media. If you need the message to go out later, you set a date and time in the scheduling screen. When the campaign is ready, the app hands the prepared message over to WhatsApp, which handles the actual delivery.
The tool is suited for a range of everyday scenarios:
The app is available as an APK that can be installed on Android devices. Because the official store link is not provided here, ensure you download the file from a reputable source and enable installation from unknown sources in your device settings if required.
Anyone who regularly needs to share the same information with multiple contacts on WhatsApp can benefit—from local shop owners and freelance professionals to community organizers and friends planning group activities.
WhatsTool for Bulk Messaging is a free utility that does not claim any special security guarantees. It operates by interacting with the WhatsApp app you already have installed, and it does not store your messages on external servers.
No. The app works with the regular free version of WhatsApp.
You can add numbers manually for a campaign, but the app still requires WhatsApp to recognize the number as a valid contact.
The app targets recent Android releases, but exact version requirements are not listed. If your device runs Android 6.0 (Marshmallow) or newer, the app should install and run.
