TagMacro

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.

Private by design

No internet permission. Android does not let TagMacro open a network connection at all.

No ads, no trackers, no analytics, and no libraries beyond the Android framework and Kotlin's standard library.

Tags written by TagMacro hold only a random code, never your messages or contacts.

Every permission is optional and only requested for the actions that need it.

Actions

Messages and calls: send an SMS, call a number, send a Signal or WhatsApp message, share live location on WhatsApp

Screen and device: brightness, screen timeout, auto-rotate, flashlight, lock screen, Wi-Fi/NFC/volume panels
