Interstitial ads for normal apps (NO games/entertainment/social).

It’s easy to monetize users in game / entertainment or social app but what with tools / utilities / audio etc apps ? What interstitial ads do you recommend ? MobileCore / Appnext / chartboos are good for games/etc but for mentioned apps something like admob interstitial. BUT admob sucks, their payment terms suck. Is airpush the only alternative? It will be nice to see ECPMs from interstitials in utilities app.

Lets face it, market and users are going for more games. for apps, airpush offer wall sucks as it automatically takes user to play store without them clicking anything. unless productivity app users are from U.S., I don’t see any good monetization solution than admob.

I thought that I missed something but looks like my feelings were right, thank you for answer.
