NFC ReTag

This app allows you to use NFC tags to perform multiple functions on your Android device. These functions can include turning off WiFi, turning on Bluetooth, starting navigation, running Tasker tasks, opening apps, using media buttons, making phone calls, adding timestamps and calendar entries, and even using Text-to-Speech. You can also set up tag cycles, which allow you to run different activities with each scan of the tag. This makes NFC ReTag a powerful automation tool for your device.

The app has an internal database where you can store all your tag activities. This means you don't have to write anything on the tag itself, making it great for small tags and write-protected tags. Additionally, no data is sent to the internet, ensuring your privacy. You can also import activity tags and use beaming to share your tag activities with others.

NFC ReTag works with any NFC-enabled device and does not require root access. If you encounter any issues, you can visit the support forum or contact the developers via email.

You can combine multiple activities and cycles on a single tag, making it a versatile tool for your device. The app also offers additional write options for better dispatching and device-independent tags. Some of the available activities include setting ringer and music volume, adjusting brightness and display timeout, connecting to WiFi and Bluetooth, launching apps and activities, making phone calls, and adding calendar entries.

Other features of NFC ReTag include unique tag cycles, the ability to write/import NFC ReTag activity tags, beaming of activity cycles, and the option to write special NFC ReTag tags for better dispatching. The app also supports Smarttags, allows you to backup and import your database, and offers the option to disable background dispatching. There is also support for placeholders, BT and WiFi triggers, and many more features. The full description and changelog can be found on the support forum.

There is a free version of the app with limited tag usage, as well as a paid ad-free version. It is recommended to try the free version first to ensure compatibility with your device before purchasing the PRO version. NFC ReTag supports all standard android NFC tags, including NFC Forum Type 1, Type 2, Type 3, and Type 4. However, it may not work with security-related NFC tags that change their ID on every read attempt.
