Does NoodleTools have a mobile version or app? How does it work?
NoodleTools does have an app for both Apple and Android mobile devices; called NoodleTools Companion. Simply go to the AppStore (iPhone) or Google Play (Android) and search for the free NoodleTools Companion app and download it.
When you download the app, there is a tutorial that will walk you through using the app (How to add/choose a project, how to scan barcodes, how to export them into your projects).
Note: as of 7/25/18, books are the only type of source you can add to your NoodleTools projects using NoodleTools Companion. If you want to add websites, journal articles, YouTube videos, newspaper articles, magazine articles, etc., you will need to go to the web-based version of NoodleTools.
