The best thing I like about learning applications is its "content creation and notification system" is very nice. One can easily create the learning contents notes using existing material just by draging the files from loacl machine to the application and thats hit. Once you create any learning content a broadcase notification to all the users who is a student receives notification on their Mobile/Computer inside Vivo app. Another good featurs of vivo are listed below : 1) Role based access to the screen and contents. If the role is admin he can add/remove user previliges and can change their roles. Students can only see the contents adn play the videos but cannot edit. 2) Student can opt for course and once he completes the course he must have to give the assesment test as well. Student can ask questions to the tutor or the content writer. 3) It has provide a good search engine which gives precise results which ultimatelly helps to find right contents fast. 4) All contents are organized very neatly in the different catagories like commerace, arts, science, programming, ML and AI, Big data, etc. 5) As a tutor you can create a assesment in the form of small game which maks the student happy and interesting to complete assesment. 6) It has a specal permissions and access to the corporate employees which helps to improve/upskill them helps make carrier growth. 7) It supports I18N as well means anyone from any rigion and country can use this application and create/learn. 8) Last but not least Dashboard is the view all at a glance.
