LoopO NFC keeps your Base Code and your identifiers where they belong:
on the NFC tags you carry, not on your phone.
The app works entirely offline and stores nothing at all. Your two LoopO
tags are the only place your data lives.
TWO TAGS, TWO SCREENS
Your Base Code is on one tag, your identifiers on the other. Each has its
own screen, and the app never mixes them up.
Key features:
Base Code: hold the front side of your LoopO to the phone and your Base
Code appears, partially masked so it cannot be read over your shoulder.
Copy the full code to the clipboard with one tap, and empty the clipboard
again when you are finished.
Identifiers: hold the back side to the phone and your identifiers are
listed, so you always know which code belongs to which account.
EDIT brings those identifiers into the Setup screen, where you can change,
add or delete them and write them back to the tag.
Setup has two independent sections, one per tag, each with its own
permanent write-protect.
Available in English, French and German.
Why choose this app?
Nothing is stored on your phone: no database, no file. Anything read from
a tag disappears when you leave the app, and the working list disappears
when you close it.
100% offline operation: the app has no network access of any kind, so
nothing can be sent anywhere even in principle. No data is collected or
transmitted.
Privacy protection: the only permission required is NFC. No access to the
internet, contacts, photos or any other sensitive data.
Security and autonomy: your data stays under your control, on tags you
physically hold.
Compatibility: iPhone with NFC (iPhone 7 or later), iOS 15 or later.
Works with standard NDEF tags.
A discreet, reliable solution for managing your LoopO tags independently
and securely.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A complete rework of LoopO NFC around two separate tags.
- Base Code screen reads your Base Code from tag 1, shows it partially
masked, and copies it to the clipboard with one tap.
- Identifiers screen reads your identifiers from tag 2.
- EDIT brings those identifiers into Setup so you can change, add or
delete them and write them back.
- Setup now has two independent sections, one per tag, each with its own
permanent write-protect.
- The app is now available in English, French and German.
- Nothing is stored in the app any more. The tags are the only storage.
Everything on screen is cleared when you close the app.
