📡 RF Tools

🔹 RF Calculator

Get quick RF calculations using simple adjustable controls:
• Set power, gain & reduction values with sliders to instantly calculate EIRP & ERP in dBm and watts
• Set frequency and distance to get open-space path attenuation (FSPL) in dB
Perfect for engineers, installers, and technicians working with antennas, routers or RF equipment.

🔹 RF Signal Detector

Start scanning to view nearby RF activity levels in real time.
Ideal for diagnosing wireless interference, checking signal presence, or performing security sweeps.

🔹 RF Signal Generator

Create and control custom test signals:
• Adjust frequency using a rotary control knob
• Select wave types – sine, square, saw
• Set duty cycle, Hz frequency & output level
• Record generated audio for later analysis
Useful for audio-frequency experiments, signal simulation & electronic testing.

🔹 RF Signal History

View previously generated RF audio frequencies with quick playback access.
━━━━━━━━━━━━━━━━━━
📶 Cellular Network Analyzer

🔹 LTE + GSM Meter

View live cellular signal strength including GSM and LTE levels for better network understanding.

🔹 5G / 4G Force Utility

• Open the device’s LTE settings page for manual network selection
• Run a compatibility test to understand operator support, band presence & network type availability
(Note: Actual network switching depends on device & carrier support)
━━━━━━━━━━━━━━━━━━
📡 Wi-Fi Quality Detector

Analyze your Wi-Fi connection with detailed metrics:
• Wi-Fi signal level in dBm
• RSSI, SSID, BSSID
• Link speed in Mbps
• Wi-Fi channel & frequency in MHz

🔹 Confidence Area Map

See your network provider’s approximate service coverage area on the map.

🔹 RF Signal Strength Graph

Visualize nearby Wi-Fi signals using live signal graphs for easy comparison.
━━━━━━━━━━━━━━━━━━
📱 Cellular Data Info

Deep device-level information including:
• SIM & carrier details
• Telephony data
• Device hardware identifiers
━━━━━━━━━━━━━━━━━━
🧲 EMF Signal Detector

Monitor surrounding electromagnetic fields with your device sensors:
• Live EMF readings in µT
• Graph-based history for trend tracking
Useful for EMF checks in homes, offices, electronic projects, and classroom demos.
━━━━━━━━━━━━━━━━━━
🚀 Internet Speed Test

Check your network performance in a clean layout:
• Download speed
• Ping & latency
• Instant network quality rating
Helpful for diagnosing slow internet or Wi-Fi issues.
━━━━━━━━━━━━━━━━━━
🔒 Permissions Used

• android.permission.ACCESS_FINE_LOCATION
Used only for the Confidence Area feature to display the approximate geographical coverage area of your network provider on the map. Location is required because Android needs it to show nearby network information and map-based coverage details.

• android.permission.READ_PHONE_STATE
Used to access basic device and network information, such as SIM data, network type, and telephony status.
━━━━━━━━━━━━━━━━━━

Get clear RF insights, stable Wi-Fi checks, EMF readings, and network diagnostics with smooth performance across all tools. The app works seamlessly with your device’s supported sensors to deliver accurate signal information and a dependable connectivity experience.

Ratings and reviews

too many ads and it doesn't even work properly.

too many ads on the free version to know if it's worth it or not uninstalled within the first 5 minutes

Unbearable amount of adds. I blindly clicked to try and get adds to close, because you can't see where to click. and I closed like 6 or 7 adds to get where I needed, and then it didn't work.
