NFC Tag app & tasks launcher allow you to launch your preferred apps and some tasks by reading an NFC tag.
First you need to write the NFC tag using the built in write functionality.

To associate a tag with installed apps or tasks you must write/read it first, then select an app and/or tasks from the tasks tabs (the apps window shows only apps that can be launched).
In the Main tab you will see what's associated to the tag, Touch a task to move it up/down or delete.
Test if the Tag will work: from Menu choose Execute Tag now! , it's the same as reading the tag (navigation task may not work in test mode).
when done, exit the app and test the tag by reading it.
The TAGS tab allow you manage saved and deleted tags.
This app must be closed (choose EXIT-> yes) for use with associated tags in order to work.
The app contains a short tutorial, please watch it at first use.
