Strong app with many useful features

This app really does everything you need to work with and debug NFC tags, especially NFC V. Version 6.02 fixed all issues I was having with the app and it is now running stable. Big thanks to the dev team!

I wish it would not automatically prompt to scan a tag when the app opens, but that’s a small gripe.

Developer Response ,

Dear Ploxfood,
Thx a lot for your feedback. We try to make your user experience easier at every iOS NFC Tap release.
Please, could you detail more the use case you re facing on ? Since previous release, we have improved the way for handling wrong CCFile . Normally, whenever CCFile is wrong, you can "play" with Tag features. It was not the case before v5.0 version, where you had to enter valid CCFile values.

Wait for more information from you in order to fix potential issue or user experience.

Thx and Br,
NFC Tap developer team
