FAQ.

Common questions from mobile app developers before integrating the Smart After Call Assistant SDK.

What is Smart After Call Assistant SDK?

It is an SDK for mobile apps that displays a helpful after-call assistant modal with caller details, quick actions, smart replies, spam tools, and an integrated ad unit.

How does the SDK help increase app revenue?

The SDK creates a new monetization moment after a phone call ends. The modal can show an ad unit, and revenue from that placement is shared with the app publisher.

How does the 50% / 50% revenue share work?

Revenue generated from the ad unit inside the after-call modal is split equally: 50% for the developer who integrates the SDK and 50% for our SDK platform.

What permissions are required?

The app may need call-related access and display-over-apps permission, depending on the implementation. The permission flow should clearly explain the user benefit before asking.

Will this interrupt the user experience?

The assistant is designed as a smooth after-call modal, not an aggressive full-screen interruption. It should feel helpful, fast, and easy to dismiss.

Can developers customize the modal design?

Yes. Developers can customize visible actions, branding, colors, wording, smart reply options, and how the ad placement is presented.

What actions can the modal include?

The modal can include call back, send SMS, save contact, block number, report spam, trust score, verified business info, AI reply suggestions, and call-later reminders.

Is this SDK only for messaging apps?

No. It is especially useful for SMS, caller ID, dialer, utility, productivity, and communication apps, but it can fit any app where after-call context is valuable.

Does the SDK support Android?

Yes. The landing page and integration flow are currently focused on Android app developers because after-call and overlay permissions are most relevant there.

How long does integration take?

Integration depends on the app architecture, but the SDK is designed to be lightweight and fast to configure with publisher ID, feature flags, theme options, and ad settings.
