Awesome App!

This is so cool. I was looking for a way to add RFID to my other spools and came across this project. Thanks for making an iOS app!!

Great little application

This is the exact application I was looking for. I had seen versions that ran on other platforms so did a search for iOs. The developer has done an excellent job of creating a version that has the iPhone look and feel from the code base for other platforms. I hope they will continue to support this application in the future.

Nice!

Haven't tried reading in the printer yet (long print running) but easily programmed the tags I had on hand and read back just fine. I thought it would read/write Bambu tags as well but wasn't able to read the ones I tried and that printer is also busy for a while to test reading those. Hopefully that's possible if not in this version then a future version! Have an S1 and X1c.
