Know the instant your network switches between 5G, 4G, 3G, or 2G
About this app
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.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.signalsense.app is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for SignalSense – Network Switch Alerts, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SignalSense – Network Switch Alerts, and a listing is removed when the evidence for it stops holding up.
