Koshe SS7 Monitor
An early warning sign when your phone's cellular signal looks wrong.
An Android app that watches your own phone's carrier, network type, roaming, and cell signalling for the on-device patterns consistent with silent SMS (Type-0 SMS) probing and SS7-style tracking or interception attempts. No app — this one included — can read or decode carrier SS7/Diameter signaling directly; every detection is a heuristic confidence score built from what Android itself exposes, never a confirmed intercept.

Silent SMS heuristic
Correlates radio wakeups, registration churn, and missing visible-SMS signals into a weighted confidence score.
Cellular anomaly detection
Flags network-technology downgrades, unexpected roaming, and cell-identity changes as they happen.
Dual/multi-SIM aware
Tracks and labels detections per SIM on dual-SIM devices instead of one SIM's changes masking the other's.
Detection timeline & history
A searchable on-device log of every detection, with CSV/JSON export.
Background monitoring
Keeps watching via a foreground service after you leave the app, with a persistent notification.
Confidence-scored alerts, never certainty
Every detection is shown as a probability (risk level + numeric score) — this app never claims a confirmed SS7 intercept.
