NetProbeX vs Fencekeeper

NetProbeX shows you what's actually on your network — not just that a device exists, but what it's running and what it's exposing. WHY NETPROBEX Most network scanners tell you "a device is here" and stop. NetProbeX goes further: tap any open port and see the exact raw data the service sends back, in hex and ASCII, just like a professional network tool. No other consumer scanner shows you this. Everything runs on your device. There's no account to create, no cloud backend, and nothing about your network is ever sent anywhere except the one optional, manual public-IP check you can trigger yourself. WHAT YOU CAN DO • Discover every device on your Wi-Fi — routers, phones, laptops, printers, smart speakers, cameras — with real names via mDNS/Bonjour, not just IP addresses. • Raw Response Inspector — tap an open port and see the exact bytes the service returns. Copy it, export it, or send your own custom probe. • Hidden Camera Finder — scan for exposed RTSP/DVR camera ports, the kind hidden cameras and unsecured IP cameras commonly leave open. • Router Vulnerability Check — a read-only look at whether your router has UPnP, NAT-PMP, or Telnet left open, the three most common home-router misconfigurations. • Real diagnostics — actual ICMP ping and traceroute (not an approximation), DNS lookup, and an internet speed test. • Wake on LAN — save a device's MAC once and wake a sleeping PC or NAS on demand. • Rename, label, and hide devices — keep notes on a busy network so you can identify the culprit fast if something causes a slowdown or an IP conflict. • Save scans and revisit them anytime. HONEST ABOUT WHAT IT CAN'T DO Apple restricts what any app — including NetProbeX — can see about other devices' real hardware (MAC) addresses, as a privacy protection. NetProbeX respects this rather than trying to work around it: device identification relies on network behavior, hostnames, and mDNS names, which is what makes NetProbeX reliable where other scanners overpromise. Built for anyone who's ever wondered "what is that device on my network?" — from home users curious about their smart devices to IT-minded people managing a busy office Wi-Fi.

You're standing in a field with a drone, and the question is always the same: how high can I legally fly here? Fencekeeper answers it. Tap the map where you're taking off — or draw your actual flight area — and it pulls the live FAA facility-map grid, checks the terrain under the whole area, and hands you the exact numbers to type into DJI Fly's Safety settings: Max Altitude and Max Distance. It even reminds you where your return-to-home altitude has to sit. And it knows about terrain — the trap almost nobody covers. FAA ceilings are measured from the ground beneath the drone, but DJI's altitude limit is measured from where you took off. Stand on a rise and fly over a valley, and your "legal" altitude quietly isn't. Fencekeeper samples USGS elevation across the whole fence, corrects your Max Altitude, and can shade the ground itself — green where your altitude is legal, amber where it's tight, red where it isn't. Then it does the thing nothing else does. Tap Track before you switch over to DJI Fly, and Fencekeeper watches your position against the fence while you fly — because pilots walk while filming, and it's easy to drift out of the area your numbers were computed for. Wander toward the edge and your phone sounds off — and your wrist too, with Apple Watch taps that quicken as you get close. What's free, forever: — Live FAA UAS Facility Map ceilings on a dark flight-deck map — Governing ceiling for your exact fence, not just the cell you're standing in — Terrain-corrected altitude limit from USGS elevation data — The two DJI Fly Safety numbers, in feet or meters, with tap-to-copy — Return-to-home altitude guidance — Pre-flight conditions: wind and gusts, Kp for GPS health, civil twilight, rain — plus a one-tap TFR check — Saved fences: name a spot, reload it in a tap, numbers recompute fresh — Warns you when your fence overlaps a 0 ft cell where LAANC can't authorize flight Pro, one purchase, no subscription: — Live pilot tracking with INSIDE / NEAR EDGE / BREACH alerts that work while DJI Fly is on screen — Apple Watch companion: fence state at a glance, wrist taps that quicken near the edge — Legality shading: the ground colored by whether your altitude is legal there — Drawn fence shapes for your real flight area — with an honest warning where DJI's circular limit can't protect you — USGS topographic and satellite map styles, fences to 8 km What it doesn't do — and you should know before you buy: it tracks this phone, not your aircraft (DJI doesn't share drone telemetry with other apps). It doesn't show TFRs, and it doesn't file your LAANC authorization — you still need an approved provider like Aloft for that. Ceilings are feet AGL from the FAA's public facility map, fetched live, so you need a data connection at the field. Built for a friend who flies, by someone who got tired of guessing.
