Where to get ideas for mobile applications?

Question

Layouts and prototypes

I develop in my free time towards prototyping and design of mobile applications.
There is no strength to come up with players, timers, calendars and all sorts of todos.
Now, basically, I'm looking for interesting ideas on freelance sites or I take old java applications as a basis.
Maybe somewhere there is a site, a centralized catalog with descriptions of application ideas that can be shifted to design?

Answer 1

Only in my head. No one will share interesting ideas. And everything is normal already.
