Find your Bluetooth things. • Bluetooth hunt — pick any nearby Bluetooth device and walk toward it. A live signal fan and distance readout update as you move, so you can sweep a room for misplaced headphones, a speaker, a keyboard or a tracker. • Steady readings — Bluetooth signal strength jumps around constantly, even when nothing moves. WiFizer now filters it, so the numbers hold still enough to act on and the list stops reshuffling itself. • Proximity at a glance — every device sits on a five-step scale from "very far, or shielded" through to "arm's reach", using the same red-to-green colours as the Wi-Fi heatmap. • Hide unknown devices — one tap clears the anonymous beacons out of the list, and it always tells you how many it hid. • Forget a network — swipe to remove Wi-Fi networks you no longer visit from My Networks.

WiFizer 3.1 is our biggest update yet: • Wi-Fi Heatmap — walk your home and watch a live coverage map draw itself over your camera view. On LiDAR iPhones, scan a room and see the heat on a real 2D floor plan and rotatable 3D model. • Personal Hotspot insights — hosting a hotspot? See every connected device with its name, IP and live latency on an animated signal meter. On someone else's hotspot? See the provider and your latency to the host and to the internet, so you know which hop is slow. • Works on cellular — no Wi-Fi? The Signal tab now shows your live connection quality (ring + 60-second chart), your network type (5G/LTE), provider, and Low Data / Expensive flags. • Apple Watch app — live signal strength and latency on your wrist while you walk the map. • Home & Lock Screen widgets — your network, provider, public IP and last speed test at a glance. • Bonjour Services — discover what every device on your network advertises: AirPlay, Chromecast, printers, shares, smart-home gear and more. • Speed test upgrades — smoother gauge, tap any point in your history for details, manage or export your results as CSV. • Signal page now shows your internet provider and public IP. • Many fixes and visual polish across all four themes. New in this release: the live signal tools (Go Live, Heatmap, Watch view) are part of WiFizer Pro — a single one-time purchase with a 14-day free trial. Everyone who downloaded WiFizer before 3.x keeps these features free, forever, as a thank-you. Everything else in WiFizer stays free for all.

• New Signal Strength screen: a live signal chart with a smooth trend line, SNR, channel/band, and Wi-Fi standard — in four visual themes. • Go Live: stream advanced Wi-Fi details in real time (via the companion Shortcut), with the screen kept awake while you watch. • Link rate shows the running average plus min/max and the instantaneous rate. • Live throughput: real-time download/upload Mbps read natively from the Wi-Fi interface. • Readability and contrast improvements across the light theme (input fields, chart labels).
