Ad-Mob is a great popular and largest tool. It helps publishers collect revenues from their mobile apps linked to relevant ads withdrawn from a huge inventory of advertisers. Simply, there is no need to sign up for a free account, and it involves basic steps as installing SDK in to the app. Revenues earned on CPC basis with CPM advertising with it as well. Even better is no need for language requirement. “AdMob Mediation” for more revenues. Fantastic features that lets you set up, deliver, monitor, and report on that campaign.

AdSense account required, ad placement limits. ECPM is absolutely terrible. May not be a viable way to support an iOS app. Review collected by and hosted on G2.com.
