A phone app that maps signal strength room by room and tells you where to move the router or add a mesh node.
The problem people are complaining about
On 2026-10-21, a thread titled “Wi-Fi: Does router height make any difference?” reached #13 in our daily ranking of tech support problems on Reddit. In tech support, people most often struggle with broken Windows installs, phones that won't charge, slow PCs, networking glitches and account lockouts; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what WiFi Spot aims at.
Who the customer is
Homeowners and renters with Wi-Fi dead zones who don't know whether to move the router, buy an extender or switch to mesh.
In short, the first customer to target is: Homeowners and renters with dead zones. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
WiFi Spot is a freemium app + affiliate idea. A phone app that maps signal strength room by room and tells you where to move the router or add a mesh node. It makes money through free scan; affiliate commissions on recommended mesh/extenders; $3 pro heatmap export.

What people say they would pay for
Short quotes from the source threads that mention money, price or cost. They are attributed to the original Reddit users and linked, and are not edited beyond trimming.
“There's a reason microwave towers exist and charge higher rent every 20 feet up you want to mount a transmission device.”— u/unapologeticjerk on r/techsupport
Pricing guess
Estimate: free scan; $3 pro export; affiliate payouts on mesh systems. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Month: Android app logging RSSI per room with a simple floor sketch. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Write a router-placement guide and track affiliate clicks.
- Build a simple Android prototype and test it with five households.
- Check what signal data phone operating systems allow apps to read.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
NetSpot, router makers' apps (eero, Google Home), WiFi Analyzer Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- iOS limits Wi-Fi signal access, which constrains the app.
- Router makers' own apps are free.
- Affiliate margins on electronics are low.
How we scored it
Opportunity score (6/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (3/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
