Two of your apps mention Montessori by name, which makes me wonder how often you are criticized for using her name in vain?

My wife is a Montessori teacher and would flip her shit if a parent ever substituted the real montessori numbers/letters (usually sand paper letters) for an app. Montessori would've surely been incredibly against an app for children young enough to learn anything from sand paper letters.

It is a big discussion in the Montessori community. Some montessorian love my apps, some wants kids to play only with wood objects... Nobody knows what would think Maria Montessori but since she was an innovator, I think she would be open-minded and uses all the tools that can help kids to learn. If you check my last app about tracing letters, the sense of touch coming from the sand paper has been replaced with sound (another sense). Anyway, I say it again: the iPad is just another tool, it does not replace all the existing materials.
