It is a smart pen for children. With the iPad, it can teach children how to write ABC, how to color illustrations, how to draw, etc., and the product development is based on the actual feedback of teachers and parents.

AppCrayon Deluxe has added a lot of interactive functions to the pen. There are six optional colors, an eraser button and a sensor on the pen.

AppCrayon Deluxe can help children master how to hold a pen and train them to do fine exercises. AppCrayon Deluxe's application includes a course on how to write ABC, which can provide real-time feedback to ensure the correct order and direction of children's writing letters. The sensor on the pen holder can monitor the strength of the child's grip and remind him/her whether he/she is holding the pen too tightly.

Children can switch the color on the iPad through the color switch button, and can also erase the content on the iPad through the erase button.

The working principle of AppCrayon Deluxe is very special. It communicates with iPad through internal high-frequency audio. There is a speaker inside it. The audio frequency emitted by the pen in "eraser mode" and "color exchange mode" is different. The iPad will monitor the audio frequency emitted by the pen through its microphone and make corresponding changes according to the frequency.

But don't worry that the frequency of these audio is inaudible to the human ear. Maybe pets will hear it, but the decibel of this audio is far lower than the volume range that harms the ear.

AppCrayon Deluxe is internally integrated with educational applications. You can open a blank canvas or select a coloring template made by famous illustrator Tim Brazier.

At present, AppCrayon Deluxe is raising money on Kickstarter, and friends who like it can support it.
