I need an app

We can make an app and we can name it as “SPACE BUDDY”.
When a person will open that app, a chat bot will appear and welcome the user
and will show up the tutorial and then 3D interface of our solar system will appear
and the person can touch any planet , orbit, axis etc. and after touching the that
the whole information will be given to the user regarding the thing which user
touched (in form of 3D videos, written, some interesting facts and some
information in voice note type) and even we can provide the user an option of
notepad so that user can jotdown the stuff if he/she wants to. After learning
about 1 particular thing we can make an option of quiz, we can make quiz of 2
types (regarding the particular thing which user touched) : one practice mode
and other competition mode. In practice mode user can practice in which only
stars will be given and in competition mode any person from anywhere in the
world can join and both can compete and points will be given to the one who will
win and the one with highest score will get a badge….And like this person will
keep learning and keep earning the score and after learning about all the planets ,
orbits axis etc. and after winning the quizzes of all planets the person will get a
certificate and a badge and finally after learning about full solar system there will
be combined quiz about solar system and then person will get a final certificate.
