In version 3 of Fongo for Android and iOS, we've added a in-app purchase option to remove visual ads from Fongo.
Here is what is included when you purchase the "Remove Ads" option:
1) Bottom Ad block removed and replaced with a handy quick menu bar
2) Ability to set a custom outgoing Call Display Name
Go to the Add Ons screen to purchase the "Remove Ads" option to enable the above features.
Please note, the "Remove Ads" purchase refers to the visual display of banner ads and interstitial ads being shown within the app. Non-Personally Identifiable analytical information may still be sent to 3rd party ad networks even though the "Remove Ads" option has been purchased.
