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


• Sound: ringer mode, Do Not Disturb, volumes, play/pause/next


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


• Apps and places: open an app, open a link, get directions


• Time: alarms, timers, waits


• Feedback and notes: on-screen message, speech, vibration, clipboard, and a journal that records when things happen


• Run another macro

Messages can include the time, date, battery level or a map link to where you are.

Triggers and conditions

• A tag written by TagMacro, any tag or card by its serial number, or a home screen shortcut


• Ask before running, cooldowns, time-of-day windows and days of the week

Tag tools

• Read: chip type, capacity, lock state, every record, and which macro a tag runs


• Write: links, Wi-Fi networks, contact cards, map locations, phone numbers, SMS, email, text, app launchers


• Erase, format and permanently lock tags

Also
Ready-made templates, a run log that shows each step, journal export to CSV, and full backup and restore.

Good to know
Signal, WhatsApp and lock-screen actions use an accessibility service that only receives events from Signal and WhatsApp and only acts while a macro is running. WhatsApp's terms forbid automated messaging, so use those actions at your own risk. Android does not allow apps to switch Wi-Fi, Bluetooth, mobile data or airplane mode on or off.
