NFC21 Tools is designed for iPhone users keen on NFC technology. The app shines with its **simple interface**, ccessible for all users. Upon opening, you are greeted with a **history view** that logs all interactions with NFC tags, which helps in tracking past activities.

The app supports both reading and writing NFC tags, offering a approach to create custom tags. Users can filter their history by categories like 'Read' or 'Written', allowing for better organisation. While the app is free, it lacks advanced features that experienced users might seek, such as custom tag configurations or more detailed analytics.

For users needing to manage multiple NFC tags, NFC21 Tools provides a decent foundation. However, for those who require **advanced NFC functionalities**, exploring alternatives like NFC Tools may be worthwhile. According to the official page, NFC21 Tools is continually updated, but the last significant update was in February 2020, which raises questions about future enhancements.
