1. Overview & Native Capabilities

Branded notification sounds increase brand recognition and user retention. Nativine's Custom Notification Sounds plugin embeds audio resources directly into native iOS and Android resource bundles:

Branded Push Chimes: Play custom ringtones or sound effects when receiving FCM / APNs push notifications.
Channel Sound Mapping: Assign specific sound files to different notification channels (e.g. chime_order.wav vs chime_alert.wav).
In-App Sound Triggers: Play bundled native audio files programmatically during web app interactions.

2. No-Code App Builder Setup Guide

⚡ Nativine Builder Feature: Custom Notification Sounds is integrated directly into the Nativine native app engine. Configure options natively in the App Builder under Add-ons & Plugins > Native UI.

Nativine App Builder Configuration

Open the Nativine App Builder at /web-to-app-converter-pro.
Click Add-ons & Plugins in the left builder menu and locate Custom Notification Sounds.
Toggle Custom Notification Sounds to ON (or click Enable), then click Config.
Configure your required settings, permissions descriptors, or target web parameters.
Click Save Config and navigate to the Builds tab to compile your mobile application.
