How does Calldorado work?

The Calldorado SDK is designed for apps that have a natural fit with phone calls. This can be anything from communication, utility, productivity, tools, business to other call-related categories. It integrates a detailed call information screen into your app which draws its information from Calldorado’s extensive database. Your app is presented directly to users following every phone call made or received. It secures daily ad impressions while simultaneously enhancing the user experience by offering advanced features.

Your app is presented at the exact moment the device is in use, and at a time when it contextually makes sense, adding value for users. This direct presentation of your app into the hands of users at the most opportune moments offers tangible enhancements to help sustain the continued use of your app and encourages engagement.

Native field template samples

Calldorado is very easy to integrate into your app, taking just minutes. To help make the integration process as simple as possible for you, we have developed a number of ready-to-go templates to present your app’s features clearly to users on the call information screen.

Here are just a few examples:


The messaging template allows users to write and send texts directly after finishing a call.


The email template makes it easier for users to write and send emails directly after a completed call.


The recorder template facilitates call recording while the phone rings, and listen to it after the call is completed.
