PPC for IOS / Android APP

Hi everybody,

finally I finished my IOS / Android app by last week. As soon as it is listed in the app stores I'm going to advertize for it.
The app is based on Google Maps and is really interactive.

For advertising purposes I'm going to do a test with Facebook sponsored messages on mobile devices - so far my only plan. Maybe I'll test some mobile newspapers as well.

So now my questions:

- any other suggestions for Ad-Networks which are big in mobile advertising
- or any other kind of advertising for an app
- is there a way to advertize in the app stores directly

Thanks in advance - looking forward for good feedback

Airpush and admob are good .

what software did you use to make the app?

LeadBolt is the best for monetization of your app.
