Ideament is a tool that allows you to build graphic organisers, which can help you organise information or your thoughts in different ways. If you prefer to map your  thoughts in point form, Ideament can change your maps to point form, or point form to maps. I liked this feature because it would take into account learner preferences that are more text-based rather than graphics-based. It's also available for both Android and Apple devices, and the ability to download the apps would be restricted by access to these devices and also parental approval of downloading apps, even free ones.
