1. You can include whatever ad network you want when building your app and remove those that are not performing. 2. After the app is live very fine control about what ad providers and format are used based on segments and/or a number of parameters. 3. Historical weekly data on how each of the ad networks has performed across all their clients not just your impressions. 4. Great reporting, for example, you can find out what hours during the day or days of the week your ads perform the best. 5. Great support. They will respond to an e-mail within a day and usually within a few hours. 6. Good eCPM. I have tried so many monetization mediators and none has been able to consistently outperform Appodeal. 7. Free adServer for cross-promotions or any direct deals you might get. And the ability to give the company that purchased your impressions to go into the Appodeal control panel and see only the performance of their impressions.

Very easy to implement and stable. Their support is great and fast. We basically doubled our revenue after we implemented Appodeal.

Working with appodeal from may 2015. And only great impressions: - high ecpm(about avg. 2.5$ for android); - easy integration with troubleshooting section, where I found how to avoid "Dex 65536" problem; - best support team; - no need to registering on many different ad networks; - possibility to request immediate payout(2% fee).
