Core01
Android notification listening
Grant Notification Listener access so Mbox can read supported payment app notifications (Google Pay, PhonePe, Paytm). This is separate from SMS or location permissions.
Product
Features built for the counter
Mbox combines an Android soundbox experience with an honest merchant cloud — so you hear payments and still understand what is unverified.
On-device TTSOffline-firstDetected ≠ verified
Voice02
On-device Native TTS
Announce eligible amounts with Android Text-to-Speech. No paid cloud voice is required for the core counter experience.
Reliability03
Offline-first journal
Events are stored locally in SQLite first, then synced when online. Shop floor announcements should not depend on flaky internet.
Trust04
Detected ≠ verified
Every UI surface separates notification detection from provider-verified settlement. Merchants see honest trust labels — not marketing fog.
Scale05
Multi-branch & multi-device
Growing shops can register multiple Android handsets and branches on paid plans with entitlement-aware limits.
Cloud06
Merchant dashboard
Web overview, transactions, devices, billing, and data export (when entitled). Cloud features activate after verified subscription webhooks — never from a redirect alone.
