Know when the same unknown device signal keeps showing up around you. VELREN helps you spot recurring signals from nearby devices that may be moving with you. Start a monitoring session and the app analyzes nearby observations alongside your movement and route. Instead of a wall of technical data, you get a clear timeline: what repeated, where it appeared, why the pattern matters, and what you can do next. SEE THE PATTERN — NOT JUST THE SIGNAL • Track detected and persistent device signals during a session • Receive clear alerts with the reasons and evidence behind them • Review events on a timeline and save important incidents • Mark trusted devices and places to reduce familiar noise • Export a report when you need a record of what happened • Capture your surroundings as a perimeter and learn if something from it turns up elsewhere • See which signals keep recurring across your days and places, ranked and explained PRIVATE ON YOUR IPHONE No account. No advertising profile. No VELREN cloud. Analysis and stored history stay on your device. Precise routes, event details, geofences, and device names are protected locally. Apple Maps may process the information required to display map content under Apple’s privacy terms. FREE PROTECTION Monitoring, every safety alert and explanation, saved incidents, one perimeter capture with its match alerts, two geofences, and basic export are included free. You can also see how many signals the observer ledger is following and the strongest level it holds. VELREN PRO — PAY ONCE, KEEP IT Unlock the full observer ranking and alerts for any signal you put under watch, more perimeter captures with your own names and a dossier, history search, cross-session signal comparison, longer retention, additional geofences, and detailed incident export. No subscription. Monitoring and safety alerts always remain free. BUILT FOR CLARITY, NOT FEAR VELREN can reveal a recurring signal pattern, but it cannot prove that someone is tracking you. Signal strength cannot provide an exact distance. iOS may limit background discovery, and no app can guarantee detection of every tracker or continuous background monitoring. VELREN does not access Apple Find My. If the same signal keeps appearing, VELREN helps you see the pattern before you dismiss it as coincidence.

Verdict
The clearest difference is in-app purchases: RobotVision at none against VELREN's 1. RobotVision also leads on update cadence (every 5 days vs every 4 weeks) and iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
