WiFi+

Slow Wi-Fi or dead zones and no idea why? WiFi+ turns your phone into a complete Wi-Fi diagnostics lab: it finds what's wrong, explains it in plain English, and shows you exactly how to fix it.

UNDERSTAND YOUR WI-FI — NO TECH KNOWLEDGE NEEDED
Most tools throw numbers at you and leave you guessing. WiFi+ is built for everyone. Every result comes with a clear explanation of what it means and why it matters. Tap the info button on any check to learn what things like latency, channel congestion, jitter or bufferbloat actually are — so you don't just fix the problem, you finally understand your network.

ALREADY WORKING? YOU CAN STILL DO BETTER
Even a connection that feels "fine" usually has room to improve — a cleaner Wi-Fi channel, lower lag for gaming and video calls, a smarter spot for your router, or hidden issues like bufferbloat that only show up under load. WiFi+ reveals the headroom you didn't know you had, whatever you use your connection for.

ONE-TAP QUICK TEST
Run a single test and get the whole picture: download and upload speed, ping, a full network health check, channel congestion, and every device on your network — followed by a prioritised list of plain-language recommendations.

WHAT'S INSIDE
• Speed test, two ways — a real-world result (like streaming or a video call) plus a max-capacity test that shows the true ceiling your ISP and router can deliver
• Diagnostics — clear checks for security, DNS, IPv6, bufferbloat, router response and more, each with a simple explanation and step-by-step fix
• Channel analyser — see how congested your Wi-Fi is and switch to the clearest channel
• Device scanner — find everything on your network and spot what's slowing it down
• Signal map — map your home room by room, find dead zones, and get the best place to put your router
• Setup wizard — check if your connection is ready for 4K streaming, video calls, gaming, working from home and more, and see exactly what's holding it back
• Live signal meter — watch your signal strength in real time as you move around
• Step-by-step how-to guides for every fix, from switching to 5 GHz to choosing the right Ethernet cable
