About this app
Turn your Android device into a powerful cellular network analyzer. CellFitch continuously scans nearby mobile cells, transforming complex radio data into clear, actionable insights — all within a thoughtfully designed, visually clean interface. Whether you’re evaluating coverage, diagnosing weak spots, or taking a closer look at nearby LTE/5G activity, CellFitch gives you the information you need—instantly.
KEY FEATURES
* Automatic Cell Scanning
Customize automatic refresh intervals ranging from seconds to minutes—or switch auto-refresh off entirely to save battery life.
* Comprehensive Cell List
View detailed information at a glance, including Operator (PLMN / MCC-MNC), Cell ID (CID / ECI / NCI), % signal strength, dBm (RSSI / RSRP), RSRQ, SINR, PCI/PSC, ARFCN (GSM/UMTS), EARFCN (LTE), NR-ARFCN (5G), band and technology (GSM / UMTS / LTE / NR).
* Quick Sorting & Real-time Filtering
Instantly sort cells by Signal Strength, Operator, Technology, Band, or ARFCN/PCI. Filter live by typing part of the operator name, PLMN, technology, or band to quickly find what you’re looking for.
* Customizable Color Highlights
Highlight specific operators, bands, or keywords using a color of your choice, helping you spot important entries instantly.
* Intuitive Signal Strength Visualization
Mini-graphs within the cell list show recent signal stability. Full-screen graphs offer detailed historical views with scan intervals from seconds to minutes and up to 200 scan points. Compare multiple cells side by side and toggle them on or off as needed.
* Quick Clipboard Copying
Double-tap any cell to copy its details to your clipboard—ideal for sharing or documentation.
* Built-in Screenshot Capability
Capture the current screen with one tap and save it directly to your device.
* Adaptive Interface
Automatically adapts to Light or Dark mode and works seamlessly in both portrait and landscape orientation. Clean, readable design ensures comfortable use across phones and tablets.
* Broad Android Compatibility
Compatible with Android 11 (API level 30) and above. No root required. (Location permission is used to access radio information.)
* Privacy-Focused
All scan data stays on your device. CellFitch collects no personal information.
ADVANCED CELL DETAILS
Explore deeper insights for each cell:
* Operator name + PLMN (MCC-MNC)
* Technology/RAT (GSM / UMTS / LTE / NR)
* Cell identifiers (CID / ECI / NCI), eNB/gNodeB where applicable
* Tracking/LAC/TAC and PCI/PSC
* Channel numbers (ARFCN / EARFCN / NR-ARFCN) and Band
* Signal metrics: RSSI / RSRP, RSRQ, SINR (where available)
* Historical signal strength graphs with full control over time range and scan points
WHO BENEFITS MOST?
* Radio/network engineers validating coverage and cell configuration
* Field technicians checking signal quality on-site
* Power users exploring LTE/5G behavior in their area
* Home users diagnosing weak indoor coverage or drop-offs
* Café or small-business owners verifying reception for customers
* Anyone seeking a clearer overview of nearby cellular activity
