Your entire smart home network. One view. HomeMapper builds a unified inventory of every device on your network, scanning HomeKit, Home Assistant, Thread, Matter, and IP at once and correlating them by hardware identifiers. DISCOVER Every method runs at once: • Apple's ecosystem. HomeKit via Apple's framework, plus Thread accessories, Border Routers, and Matter. • The network itself. Bonjour, subnet scans, and protocols like SSDP/UPnP. Printers, NAS boxes, and other local-only devices show up too. • Home Assistant. Direct read of your device registry: Matter, Thread, Zigbee, Z-Wave, ESPHome, and MQTT. When a device appears through several methods, HomeMapper merges it by seven hardware identifiers, not names. If HomeMapper isn't sure two entries are the same device, it lists both. YOUR DEVICES, EVERY DETAIL See devices Apple's Home app can't, and details it doesn't show: manufacturer, model, firmware, serial number, battery, IP and MAC address, and how each device connects, in columns like Connected via, Signal, Channel, and Stability. A room-based view groups them by room. TOPOLOGY MAP The Topology map shows how your devices connect: your Thread mesh, from the border routers down to the end devices they carry, your Zigbee network from Home Assistant, and each HomeKit bridge with the accessories behind it. It draws only connections it can measure. Tap a device for its full detail, or tap a connection to see its signal strength and how stable it has been. A red triangle marks a connection that is not working: weak, dropping traffic, or gone quiet. When a device will not report how it connects, HomeMapper shows that rather than guessing. A Health view lists what needs attention on your mesh, worst first: what is wrong, which devices, and one thing to try. Most homes show "Everything looks healthy." Export the map as a PNG, PDF, or SVG, titled with the home and dated. HOME ASSISTANT HomeMapper scans your Home Assistant servers as deeply as HomeKit, including the Thread mesh behind their border routers. Zigbee, Z-Wave, ESPHome, MQTT: devices HomeKit can't see appear alongside the ones it can. Pick a Primary Platform, and its room names win when a device is known to both. PLACES Scan more than one location, like your home and a relative's. Each Place holds its own Apple Homes and Home Assistant servers, and the app shows one Place at a time. HomeMapper picks the Place from devices on its local network, not your location. SETUP CODE VAULT Every HomeKit, Matter, and Z-Wave device has a setup code on a sticker that fades or gets lost. You need it to pair the device, and again if you reset or move it. No scan can recover one: setup codes never travel over the network. Save each code while you still have it: scan the QR with the camera, pull it from a photo, or type it in. It reads printed 8-digit codes too, for older accessories without a QR. A room-by-room list shows which devices are still missing one. Have a lot? Export a CSV worksheet, fill it in on a computer, and import it back. Your codes are stored on your device, in your backups, and synced through your own iCloud. EXPORT AND BACK UP Export your inventory to CSV, filtered how you want, for Numbers, Excel, or Sheets. Back up your inventory, settings, and setup codes to iCloud Drive or a local folder, and restore on another device. PRIVACY No ads and no tracking. Nothing leaves your device unless you send it. No account, and the only login is your own Home Assistant. FREE AND PRO HomeKit scanning, the device list, the room-based view, and switching between Apple Homes are free forever, with no scan or time limits. Pro adds multi-protocol scanning, all 20+ columns, Places, Home Assistant, the Topology map, the setup code vault, backup and restore, and CSV export.

GearTech OS replaces the box of single-purpose calculators in your truck with one app built for the trades — by someone who works them. Pick your trade and get tools made for it: pipefitting, welding, electrical, framing, concrete, HVAC, plumbing, machining, solar, sheet metal and automotive. No pipe jargon cluttering the electrician's screen, no electrical keys on the welder's — each trade gets its own tools and its own keypad shortcuts. EVERY result shows the math. Tap "Show math" under any answer to see the formula, your numbers plugged in, and the result. Learn it, trust it, and check your work in the field. REAL diagrams. Every tool draws what you're building — a 3D rolling offset box, a butt-weld elbow you can cut to a custom degree, a saddle/fishmouth, a reducer cone, roof rafters, conduit fill, ducts, gears and more. NEW — CRANE HAND SIGNALS IN 3D. 22 ASME B30.5 signals. The signal person gives the signal and the crane performs the motion, with the load always plumb. Spin the camera and watch it from wherever you have to stand. NEW — FLANGE BOLT-UP. Target-stress torque by bolt size, material, lubricant and percentage of yield, with the 30/60/100% passes worked out and the tightening order drawn for 4 to 32 bolts. Built for pipefitters and welders first: - Pipe offsets, rolling offsets, fishmouth/saddle templates, miters, trunnions, reducers (concentric & eccentric), and ASME B16.9 fittings with custom degrees - Spread/line banks, slope/grade, thermal expansion - Crane hand signals in 3D and flange bolt-up torque - Constants cheat-sheet and a 272-question practice EXAM for the NITC / UA STAR, including crane signal person — every question explained step by step, and the app remembers what you missed Plus 100+ tools across 10 more trades: - Electrical: voltage drop, conduit fill (NEC), box fill, ampacity + derating, motor FLC, 3-phase power, stub-up take-up - Framing: rafters, hip/valley/jack, stairs, pitch, baluster spacing, board feet - Concrete: slab/footing/column volume, bags, rebar, blocks - HVAC: tonnage, CFM, duct sizing (round & rect), friction rate, sensible BTU - Plumbing: drain slope, DFU, fixture units to GPM, pipe sizing, gas pipe - Machinist, Solar, Welding, Sheet metal, Automotive Works 100% offline — the 3D included. No account, no ads, no tracking. Your settings, cut lists and memories stay on your phone. Bilingual: English and Spanish, switch anytime. We build the world around us. Our tools should be built for us. — Per Diem Syndicate
