FlockHopper

FlockHopper shows you where license plate reader cameras are and routes around them. Every camera in the Deflock/OpenStreetMap database is on the map. Ask for directions and you get two routes — the fastest and one that avoids known cameras. Alerts warn you when one is nearby, whether you're navigating or just driving. Most of the app is free: directions, turn by turn navigation, camera alerts, background detection, CarPlay, Live Activity, Free Drive, saved places, Siri Shortcuts, and the full camera map. Users that upgrade to FlockHopper Pro get custom alert tones and timing, exposure stats, multi-stop routing, longer routes, offline maps, extra map styles, and live traffic. No account, no ads, no analytics, no trackers, no data sales. Route requests go to FlockHopper's own servers, and nothing is logged. Built by the developer behind maps.deflock.org, working closely with the DeFlock community on camera data. One person, no investors. There is a Tip Jar if you want to support the project. It doesn't unlock anything. Camera data is crowdsourced by DeFlock and the OpenStreetMap community. Coverage varies and won't always be current. FlockHopper reduces your exposure to surveillance networks but doesn't eliminate it. Drive safely. Not affiliated with or sponsored by any surveillance vendor.

Verdict
The clearest difference is in-app purchases: RadarCopter at none against FlockHopper's 4. RadarCopter also leads on update cadence (every 5 days vs every 2 months). FlockHopper's advantage is ads (none vs shown) and chart position (#62 vs unranked). On price, device support and iOS requirement there is nothing between them.
