Greetings,
It would be a pleasure to me help you in the project, i have an idea about what you want, let me tell you, my strenght is Unity3D and some others modeling and compilation systems, i know about PhoneGAP, but as i said, i can do the project direct to a .apk. i don´t know if i am in the correct way, with the information inside the app (Like points and actions) what i understand is, you want to create a social media interaction or compile a data base with information. You can look for some of my projects in the portfolio in DevianART, my user is ¨Gmanu93¨, my experience is based on games for local purpose, but i have some others projects in the way, (From virtual reality to web games).
If u want a game, i am your designer.
