RFMeter turns Android telephony and location data into practical RF intelligence.
RF trends
Spot change as it happens
Follow signal and quality trends over time with matching metric colors.
Drive-test heatmap
Color the route by RF, RAT, or PCI
Visualize RSRP, RSRQ, SINR, technology, and serving PCI along your trail.
Cell-file overlays
Sites and sectors in context
Import large cell files, match serving cells, render azimuth sectors, and label sites.
RF events
A timeline that explains the drive
Capture cell changes, RAT transitions, weak coverage, poor quality, and field events.
Built-in RF AI
Ask the drive. Find the evidence. Share the report.
Ask natural-language questions about coverage, quality, mobility, events, and worst locations. Then turn the analysis into a professional automated PDF drive report.
CSV logging
Detailed records ready for analysis
Log RF, GPS, neighbors, modem states, events, and speed tests with automatic rotation.
AI built for RF field work
Your drive already has the data.
Now ask it questions.
RFMeter combines the active RF session, route samples, serving-cell changes, modem state, events, and speed tests to give its AI assistant the engineering context behind the drive.
Ask Your Drive
Investigate weak coverage, poor quality, mobility concerns,
technology changes, and the worst measured locations in plain
language.
Automated Drive Report
Generate a structured engineering summary with evidence,
significant events, limitations, and prioritized recommendations,
then save and share it as a PDF.
Your provider. Your personal key.
Choose Gemini, OpenAI, or Claude. RFMeter protects your key with
Android Keystore-backed secure storage and never saves it to
Firebase or drive logs.
Where were the main coverage problems, and what evidence supports them?
✦ Drive analysis
Primary concern: route segment near Event 14
RSRP fell to -116 dBm while SINR remained below 0 dB across multiple samples. The device stayed on LTE B3 / PCI 184 during the affected segment.
- Coverage evidence identified from measured samples
- RF events and serving-cell changes correlated
- Recommendations separated from observed facts
AI output is advisory and should be validated by an RF engineer.
Simple field workflow
From first sample to actionable evidence.
Monitoring begins automatically. Import a cell file when available, follow the route, ask the AI assistant what happened, and export the evidence.
