US$29.95 for a smart stylus? What's the catch?

There is NO catch! The design of the Sonar Pen is fundamentally different. Conventional smart styli are self-contained and have their own "brain", battery and communication circuit. By contrast, the Sonar Pen is created as an extension of your iPad, it contains minimal components just enough to get the job done.
The result is a big cut in production cost with no compromise to all the standard features of a smart pen.

Testimonials

I found Sonar Pen to be very responsive. It gives the right amount of traction, that makes drawing on the iPad easy. For only US$29.95, I will definitely recommend Sonar Pen to my illustrator friends and anyone who like to start drawing on the iPad.

The Sonar Pen is very nicely designed, pretty smooth and fairly responsive when I tested it in a note-taking app. With integration to more apps in the works, it promises to be a truly affordable, hassle-free starter stylus that works with any iPad.

I wish Sonar Pen was available, when I bought my iPad Pro and Apple Pencil to take notes in class. I always forget to charge my Pencil.
