TagMacro turns cheap NFC stickers into buttons. Tap a tag with your phone and it runs a list of actions you chose: silence the phone at bedtime, tell someone you got home, start a timer, open your maps app in the car, or note when you fed the cat. It is also a complete tag tool: read any tag, and write links, Wi-Fi details, contact cards and more that work on any phone, with no app needed. <b>Private by design</b> <ul> <li>No internet permission.
