Field reporting for disaster response. RDAP puts damage assessment and situation reporting in the hands of everyone working an incident. Reports from the field flow into the RDAP EOC platform, where coordinators build the operational picture that drives resource decisions. REPORT FROM THE FIELD Submit structured reports without paper forms or radio relay. What you observe on scene reaches coordinators as soon as you hit submit, with no transcription step in between. WORKS WITHOUT SIGNAL Coverage in a disaster area is unpredictable. Create reports, attach photos, and log assessments with no connection at all. RDAP holds everything on the device and uploads automatically the moment service returns, so nothing is lost in a dead zone and no one has to reconstruct what they saw hours later. STRUCTURAL AND INFRASTRUCTURE ASSESSMENT Document the condition of buildings, roads, bridges, and critical infrastructure. Attach photos and location data so coordinators can prioritize resource deployment and evacuation decisions on current information. RESOURCE AND RESPONDER STATUS Update the position and status of response units and teams from the field, keeping the EOC's operational picture accurate as conditions change. POPULATION AND CASUALTY STATUS Record population status and casualty information by location so coordinators can identify which areas need medical response first. ONE PICTURE ACROSS JURISDICTIONS Reports from state, county, and city teams land in a shared operational picture, so agencies working the same incident work from the same information. FOR RESPONDERS AND VOLUNTEERS State, county, and municipal emergency management agencies EMS, fire, and law enforcement Emergency operations center staff Damage assessment and CERT teams Volunteers joining relief efforts RDAP is a reporting tool and does not replace 911 or official dispatch systems. In a life-threatening emergency, call 911. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

ReceptionRating · Positive reviews · Number of ratings

RDAP Pro holds the better App Store score, 2.8 against 2.3. That said, the two scores are not equally well evidenced: AntScope has 52 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 23% of AntScope's written reviews are positive against 0% of RDAP Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AntScope ships an update every 2 months, RDAP Pro every 3 weeks. The most recent releases landed on October 12, 2026 and September 23, 2026 respectively.
