Cross-Platform Call & SMS Forwarder

I’m building a small suite that lets end-users redirect both voice and text traffic exactly the way they want while I handle the configuration from a single web dashboard. The job covers three components:

• Android and iOS apps
• A web-based admin panel
• Full, well-commented source code

Core behaviour
The apps must forward all incoming calls by default, yet also let me set exceptions so only numbers I list are redirected when needed. SMS forwarding follows the same principle, but with an extra layer: I can choose to push every message, only those that contain specific keywords, or just those arriving from numbers I flag.

Admin panel
Through the browser I should be able to:
– Add or edit forwarding rules for each device (all, keyword, specific numbers)
– View real-time logs of calls and messages processed
– Toggle features per user or device
– Manage basic user authentication and permissions

Technical notes
• Both platforms should feel native and remain compliant with the latest Android and iOS permission policies for call/SMS handling.
• The apps need to run unobtrusively in the background and survive reboots where the OS allows.
• API endpoints for the panel must be secure (token-based auth, HTTPS).
• I’m open to native Kotlin/Swift or a robust cross-platform stack such as Flutter or React Native—whichever delivers reliable telephony integrations on both OSes.

Acceptance
Once you deliver the builds, source, and a short deployment guide, I’ll test end-to-end forwarding scenarios from the panel. If calls and messages route correctly under each rule set and the logs reflect the activity, the project is complete.
