★★★★★ Purchased full version but this app is junk , free apps are better
★★★★★ Maybe I'm doing something wrong, but it wouldn't read anything.
★★★★★ This is not reliable since the chips are now placed on replica bags or anything so this tool will read a replica but it can still be fake!

★★★★★ This app made it incredibly easy to create my nfc business cards myself.
★★★★★ Is really friendly and easy to use

14 of the 4 and 5 star reviews.
★★★★★ Works just how I need it. Better than blocking everything behind a paywall.
★★★★★ But I went over the instructions again, and it works perfectly!!
★★★★★ I absolutely love technology and I deeply appreciate quality applications like this.
9 of the 4 and 5 star reviews.
★★★★★ I recommend you purchase - it is worth it!!
★★★★★ You guys should take some donations
★★★★★ Id say for sure the pro version is worth it just for the save/ load feature, $3.99 for life isn't bad, and its interface/ intended use is exactly what you'd need for basically anything nfc.
7 of the 4 and 5 star reviews.
★★★★★ Funny how I'm writing a review for a product that I bought that's for “writing reviews” anyhow, it's a great app easy to learn and overall very helpful.
★★★★★ It has been very helpful for writing to my first batch of blank NFC cards.
★★★★★ It has a lightweight interface, but does everything needed and does it well. With this app, I am able to get in, get the job done, and get on with life.
