hi

i need to create some product advertisement apps , there are some menus on home ( main menu , products , about us , contact us )

and i want this app work and load picture of products in offline mode without internet ( there are about 30 products that i want introduce them with images and texts )

im confused which one of these ways can do it for me faster , easier and give me more options to design nice Graphical environment for my app :

• android studio
• phonegap
• online websites like AppYet
• or some weired technics like using Unity for create nice GUI
