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.

Who is this SDK built for?

Smart After Call SDK is built for mobile app developers and publishers who want to improve user engagement and create new monetization opportunities outside the main app experience.

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.

Can I monetize users outside my app?

Yes. The SDK helps you reach users after a call, creating an additional interaction point beyond the standard in-app session.

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.

When and how will I receive my earnings?

Earnings are paid on a NET 30 basis. You will receive payment within 30 days after the end of the previous month. To receive payment, you must issue an invoice for the approved revenue share amount. Payments are made via bank transfer to your company’s bank account.

How can I track my revenue from the SDK?

You get access to a detailed dashboard where you can track SDK performance and revenue from the SDK ad unit for each of your apps. After logging in to the client dashboard, you can see detailed information about earnings generated by the ad unit implemented inside the Smart After Call Assistant modal. Revenue data is refreshed once every 24 hours.

Is Smart After Call Assistant SDK annoying for users?

No. The user does not see a full-screen modal immediately after a call. After the call ends, the user only receives a notification. The Smart After Call Assistant modal is shown only after the user taps the notification. We never cover the entire screen automatically. The experience is designed to be helpful, non-intrusive, and focused on actions users may need after a phone call.

What is the main benefit for app developers?

Smart After Call Assistant SDK helps developers monetize users even outside their app. You can generate revenue from your user base even when users do not open your app. The SDK creates a new monetization opportunity after phone calls and can significantly increase your app revenue.

What is the benefit for your users?

Your users get useful tools they may need immediately after a phone call. They can quickly call back, send a message, save a contact, create a note, set a reminder, add a calendar event, send an email, share a location, or block and report spam numbers. The SDK can also help protect users from spam and scam calls.

Is your SDK compliant with Google Play and AdMob?

Yes. Smart After Call Assistant SDK is designed to comply with Google Play policies and advertising platform requirements, including AdMob. Every integration is individually reviewed to ensure that the app, permissions, and user experience meet applicable platform guidelines.

What permissions are required?

To enable the Smart After Call Assistant experience, the app may require permissions related to phone call state, notifications, and contacts. Before asking for access, the permission flow should clearly explain why each permission is needed and how it benefits the user.

Can developers customize the modal design?

No. The Smart After Call modal is designed and optimized by our team to maximize user engagement, ad performance, and conversion rates. The modal automatically adapts to different call outcomes such as completed calls, missed calls, spam calls, busy calls, and other scenarios. Based on the call status, the SDK intelligently displays the most relevant actions and information that users are likely to need at that moment.

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 Smart After Call Assistant SDK localized?

Yes. Smart After Call Assistant SDK is localized into 70 languages, making it suitable for apps with a global user base.

What advertising platforms do you use?

We use multiple advertising networks to maximize fill rates and revenue performance, including AdMob, Meta Audience Network, AppLovin, InMobi, and other leading demand sources. Our mediation approach automatically selects the best-performing ads for each user and region.

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.

How can I start monetizing with Smart After Call SDK?

Simply fill out the SDK access request form and submit your Google Play app for review. Our team will evaluate your application and respond within 2 business days. If your app meets our quality, policy, and monetization requirements, we will provide SDK integration instructions and onboarding support.
