RadioDig

Find every tower. Know who owns it. A tower on the horizon. A site on your route. A name behind the infrastructure. RadioDig brings public records onto one map so you can move from location to context. FOUR SOURCES. ONE VIEW. Explore antenna structures from the Federal Communications Commission (FCC) Antenna Structure Registration (ASR) database, licensed sites from its Universal Licensing System (ULS), Federal Aviation Administration (FAA) obstacle records, and broadcast stations. RESEARCH THE SITE. Search by place, ZIP code or coordinates. Explore site records and ownership information to understand what youβre looking at. TAKE YOUR RESEARCH INTO THE FIELD. Download map areas before you head out, then access downloaded maps and records when a connection is unavailable. FOLLOW PUBLIC FILINGS. Browse public notices and their filing windows in the app. RadioDig is an independent research tool, not affiliated with the FCC or FAA. Public records are not an exhaustive inventory of every tower or transmitter. Record availability and detail vary by source.

Verdict
The clearest difference is update cadence: RadioDig at every 6 days against VOLT ELD's every 3 months. VOLT ELD's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
