Frustrated by silent drops from 5G to 4G? SignalSense alerts you the instant your network changes – giving you the power to pause downloads, save your data, and avoid unexpected charges.

SignalSense continuously monitors your mobile network and notifies you whenever your connection switches between 5G, 4G, 3G, or 2G – helping you identify network issues before they affect calls, streaming, gaming, or downloads.

FEATURES

- Instant Alerts
Get notified the moment your network drops from 5G to 4G, or 4G to 3G. Stop wondering why your video buffered – know exactly why.
- 5G SA and NSA Detection
Accurately distinguishes between 5G Standalone (SA) and Non-Standalone (NSA) connections – not just "5G".
- Custom Ringtones & Vibration Control
Choose your own custom ringtone and control vibration settings for network alerts.
- Live Speed and Ping
See real-time download and upload speeds in the persistent notification, and live ping on the home screen.
- Call-Aware Alerts
Alerts are automatically held during active phone calls and fired after the call ends. No interruptions at the wrong moment.
- Anti-Spam Debouncing
Rapid signal fluctuations are detected and grouped into a single "unstable signal" alert instead of spamming your notification shade.
- Switch History Log
Every network change is logged with a timestamp and network speed. Review your full connection history at any time.
- Fully Customizable Alerts
Choose exactly which transitions alert you:
- Network Upgrade
- Network Downgrade
- Mobile Data Lost / Restored
- Any Network Change
- Smart Auto-Start / Auto-Stop
Monitoring can automatically start when mobile data turns on and stop when it turns off – completely hands-free.
- Boot Auto-Start
Optionally start monitoring automatically every time your phone boots.
- Dual SIM Support
Choose which SIM slot to monitor or use Auto mode to always follow your active data SIM.
Switches instantly when you change your default data SIM.
- Battery-Friendly
Uses a lightweight foreground service with minimal battery impact. Built for all-day use.
