Don't expect much from this free app – ABC Letter Tracing – Free Writing Practice for Preschool Review

Pros: provides a dotted set of cap and lowercase letters to scribble on. Fairly intuitive for my kid. Has potential for improvements. Free! Cons: Ad tab is annoying on a kid app, thankfully in-app purchases can be locked. No feedback on the traced item, quite basic interface.
