The WTR Notebook App is a writing app with a sounding keyboard. Using the app, you can listen to the letter sounds while you are writing, and hear your text being read by a speech synthesizer. You can insert images from your image library or take new pictures with your camera. Focusing mainly on kindergarten, pre-school and school, the WTR Notebook App supports multiple users, making it a perfect tool for environments where several users share the same iPad. 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. The finished text can be converted into a PDF or saved as plain text for Microsoft Word or Apple Pages. Additionally, text files can be imported from other sources such as DropBox, OneDrive, Google Drive, iCloud. The WTR Notebook App provides many possibilities for teachers and parents to adapt the contents of the app such as spell check, autocorrect, language, and speech synthesizer. The app contains no in-app purchases, rewards, music or sound effects. The sounding keyboard supports Swedish and English, whilst the sound synthesizer can be used with any language supported by Apple. This app has full support for Voice Over.
