If you have sent some inappropriate text messages to your friend and want to delete it from his/her device permanently, a new app called Strings could help you do so.
The app has been developed by Be Labs, a Seattle-based tech firm. It gives users complete control over their personal conversations.
The app allows you to take back your messages by controlling the feature “if and when content is deleted, immediately and permanently”, CNBC reported.
The recipients must also have the app installed on their phones for it to be effective.
Strings is available for download in the iOS App Store.
