RFLossIOS vs Sensor Viewer

RFLossIOS helps you evaluate radio links between two locations on an interactive map. Set two points, search for towns, inspect the path, and view line-of-sight and terrain profiles. The app highlights possible obstacles along the route and provides RF calculations including FSPL, received power, noise floor, SNR, and link margin. It is designed for practical field-oriented link planning for VHF and higher frequencies. Obstacle and terrain sources include OSM buildings, AHN5 DSM/DTM for the Netherlands, Copernicus DEM 30m, and NASA SRTMGL1 where available. Building height data depends on the selected source and may be incomplete. FSPL calculations are intended for VHF and higher frequencies, and only when the path has no blocked LOS obstruction.

Visualise the data from 3 of your phone's sensors And adjust the sensitivity of the sensors to match the sounds, vibrations or magnetic fields you're measuring For sounds: See a sound wave for all sounds picked up by the microphone For Vibrations: See 3 line graphs showing the movements of the phone, 1 line per dimension (up/down, left/right, forwards/backwards) For Magnetic Fields: See a graph of the magnetic field your phone can detect, even if that's just your speakers or the batteries in some of your other devices Supports Light Mode / Dark Mode Supports Dynamic Text Sizing Supports English, French, Spanish, German Optional one-time in-app purchase available to remove ads permanently.
