nofication_hub

Project information

notification_hub is a lightweight, open-source Android application built in Kotlin that monitors incoming SMS messages from user-selected apps in real time and automatically initiates a voice call to deliver a pre-recorded alert. Unlike many approaches that depend on external servers, notification_hub processes all notifications locally, offering maximum privacy and full customization tailored to each user.

Key Features: • Real-Time SMS Detection: Constantly monitors designated SMS sources and instantly detects incoming messages. • Automated Voice Alerts: On receiving an SMS, a phone call is automatically triggered to play a pre-recorded alert message. • Local Multi-Channel Integration: Offers on-device support for local Discord and Telegram bots, meaning each user’s bot is integrated directly into the app. • Customizable Settings: Users have full control over SMS sources, voice messages, and notification channels, with settings securely stored on the device. • Efficient On-Device Operation: Designed to run seamlessly in the background with minimal impact on battery and system resources. • Available on F-Droid: Distributed via F-Droid to ensure free and privacy-respecting access.
