WA Helper is a free Android app developed by Mighty Robot Studios that lets you know what messages, images, and videos were sent to you even after they have been deleted. It works by making a backup of the message as soon as it appears in the notification panel, and if the sender deletes it, the app will notify you immediately. Additionally, the app checks your storage to see whether any file was deleted, and if so, it will notify you as well.

The app also allows you to read messages without blue ticks, view deleted media files, and check the download status of any file. The user interface is easy to navigate, and the app is only about 2 MB in size. However, it's important to note that WA Helper can only recover messages that you have received after installing the app, and it can only recover media files if they were present on your device before they were deleted.

Overall, WA Helper is a useful app for anyone who wants to keep track of their deleted messages and media files. If you have any feedback or suggestions, you can send them directly to the developer through the app or via email at
