Description
DenyCalls helps Android users reduce unwanted calls by letting trusted contacts ring through while other calls are screened according to the user’s settings. No account is required, filtering happens on the device, and the app includes a 7-day free trial. DenyCalls is designed for people who want more control over unknown calls, spam and phone scams.

Could you build this?
Partial While the UI and settings can be vibe-coded, reliably intercepting, screening, and managing incoming calls on modern Android requires deep knowledge of Android Telecom frameworks, CallScreeningService, and restrictive OS permission handling.
What it would actually take: The app requires native Android development (Kotlin) leveraging Android's `CallScreeningService` or `InCallService` APIs, requesting sensitive `READ_CONTACTS` and `MANAGE_OWN_CALLS` permissions while handling manufacturer-specific battery optimization killers. The challenge lies in complying with Google Play's strict policy exceptions for call-screening roles and managing background service lifecycles deterministically.
