As a teacher or a parent, you are able to create as many accounts as you wish. You can easily switch between different users. Users are only able to view their own texts. Using the WTR Notebook App, the writer will type words using the sounding keyboard. Pressing the letter key, the app will sound out the letter for the writer, in order to connect the sign of the letter to its sound. Every word is read by the speech synthesizer when the writer hits space or a punctuation mark. The writer can move back and forwards in her text and listen to the whole text at any time. This makes text development easier. The WTR Notebook App enables you to create any number of documents. This app allows you to choose between several fonts, some similar to hand-written letters.

Periodic Table's advantage is price ($1.99 vs $4.99). On ads, in-app purchases and device support there is nothing between them.
