I want to develop a complex app, but I want to start with the core of it. Would be a app that by cellphone network(not gps) find your position. Then by it and also using the cellphone sensors, know when you are 10 minutes in the same place and ask you what is this place. It will only ask once, after it will detect automatically and by the end of the day , will show you report of how you spent your day.
It will have few fuctions like:
When you are at home and do not move the phone for 2 hours, It will auto-detect you are sleeping.
It will record automatically how much time you spend in transit(car&bus&train)
it will have few default categories (like home,work,exercise,pleasure,sleep,transit) and customize subcategory(Like Exercises>Gym,Soccer,Running,etc)
Second phase,(its not inlcude now) I want to clone "tinder" but to use the profile made above for social searching.
