No tactile with horrible sound! – Montessorium: Intro to Cursive Review

I tried this app because being a guide I wanted to be aware of technological enhancements or tools for the original materials. While I enjoy the visual it misses the critical aspect of tactile perception. Also, the scratching noise of tracing the sandpaper sounds like nails on a chalkboard! Ich!! I'm not recommending to parents until they change sound minimum.
