NFC ReTag

NFC ReTag is a powerful Android app that lets you automate your device functions using NFC (Near Field Communication) tags. It supports re-using write-protected NFC tags like hotel key cards, access badges, and key fobs by leveraging the tag ID rather than rewriting data. Users can assign multiple actions — such as toggling Wi-Fi, Bluetooth, mobile data, launching apps, running Tasker tasks, setting alarms, adding calendar events, using text-to-speech, and more — to a single NFC tag, including cycles of activities per scan for advanced automation.

With no root required and full privacy (no data is sent over the internet), NFC ReTag provides an extensive list of device controls, wireless networks options, phone call and messaging capabilities, and miscellaneous features like creating timestamps, pop-up messages, or invoking special codes. Additional features include backing up and importing tag databases, support for placeholders, and seamless integration with Tasker. It's compatible with all standard Android NFC tags and offers free and pro versions for varied usage needs. Perfect for users looking to make everyday tasks more efficient through NFC-driven device automation.
