Find out where to put your router so WiFi works in every room
Perfect WiFi analyzes your floor plan and shows you the best spot for a router or mesh node. It accounts for walls, distances, and the places where you actually need a strong signal.
Wherever you're starting from
Building, dealing with dead zones, or wondering where to put a second mesh point — pick your situation and the wizard adapts the whole process to it.
Building / renovating
No router on hand and no measurements — the app uses a general signal propagation model to show, right from the floor plan stage, where to run the outlet for your router.

Full version — step-by-step planning
The wizard guides you through the whole process, adapting every step to the mode you chose and the number of floors.
Wall detection
Analysis of your uploaded plan detects the walls automatically — you can always fine-tune the result with two taps.
Multiple floors
Multi-storey home? Add the ground floor and upper floors — the recommendation is calculated together, with a penalty for attenuation through the floor slabs between levels.
Router or mesh?
If the router's position is already fixed and can't be moved, the app switches to finding the best spot for a node — also checking the quality of the backhaul link.
Scale and dimensions from the plan
Mark two points of a known distance on your uploaded drawing — the entire floor geometry is calculated automatically.
The spots you care about
Mark the TV, the desk, or the bedroom — the algorithm makes sure even the weakest of these spots gets a solid signal, not just a good average.
Live measurement
Stand in a given spot and tap the plan — the app saves the real signal reading and fits the propagation model to it.
We don't guess where to put your router. We calculate it.
Perfect WiFi takes into account what actually weakens the WiFi signal in your home — and uses that to point out the spot where it will be strongest exactly where you need it.

Protects the weakest corner of your home
Instead of optimizing for average coverage, the app looks for a position where even the furthest room gets a solid signal — not just the one closest to the router.
Checks an extender before recommending it
Before suggesting a spot for a mesh node, it makes sure that node will have a good connection to the router — otherwise the extender would just relay an already weak signal.
Suggests spots you can actually use
Suggestions stay close to walls, near outlets — because the router has to stand somewhere anyway, not float in the middle of a room.
The more measurements, the more accurate
In the “I already have WiFi” mode, every additional measurement refines the result for your walls and materials — it's not a one-off guess.

Before you open the app
Short answers to the most common questions about WiFi coverage at home — no guessing.
Before you start
Does the app send my floor plan or location anywhere?
No. The uploaded plan, walls, measurements, and recommendations are calculated and stored only on your phone. The location permission is required by Android to read WiFi signal strength — the app never sends it anywhere.
Is the router position recommendation guaranteed to be right?
In “Building / renovating” mode it's a physical model based on typical wall parameters, clearly marked as a starting point to verify with a measurement once you move in. In “I already have WiFi” mode the model is fitted to your real measurements, so it's more accurate.
I don't have a router yet or don't know where to put it — can I still start planning?
Yes, that's exactly what “Building / renovating” mode is for. You skip the step of setting the router, and the app suggests the best spot based on the plan and the rooms you marked.
I have a mesh network with the same SSID on multiple devices — can the app tell them apart?
Yes, in scanning mode you can mark which BSSID is the router and which is the extender/node — this distinction is also visible when planning positions.
Which phones does Perfect WiFi work on?
The app is available for Android (from version 8.0). An iOS version is not currently available.
Does Perfect WiFi work without an internet connection?
Yes. Planning, calculations, and measurements all run locally on your phone — an internet connection isn't needed for the planning process itself.
Do I need to know the exact dimensions of my home?
You don't need to know them by heart. Just mark two points of a known distance on your uploaded plan — the rest of the geometry is calculated automatically.
Can I use a photo of my floor plan instead of a project drawing?
Yes. You can upload either a PDF of the floor plan or a plain photo of it — for example one taken on your phone at the developer's office or an architect's studio — and use it as a background to mark walls and rooms.
Does Perfect WiFi work in a multi-storey home?
Yes. The app supports multiple floors within a single project, calculating the recommendation while accounting for signal attenuation through the floor slabs between levels.
Does the app work with every router?
Yes — Perfect WiFi is based on the physics of signal propagation and your own measurements, not on a specific router model, so it works regardless of manufacturer or provider.
Can I plan several mesh nodes at once?
Yes. You can mark several planned nodes on your floor plan and check, for each one, whether it will have a solid link to the router.
Put your router where the signal actually reaches
Upload the plan, mark the walls and the spots that matter to you — Perfect WiFi will work out the rest.
