About WiFi Signal Finder: Best Spot
An app that shows where your WiFi reaches well at home and where it does not. It shows the current signal in big, clear numbers, and lets you walk around and find the strongest spot by sound. Technical terms are replaced with plain words wherever possible.
■ See your signal at a glance
The strength of the WiFi you are connected to is shown on a meter and in five plain words, from "Excellent" to "Very weak". You also get the dBm value and a line of the last 90 seconds, so you can see how it changes as you move. It shows whether you are on 2.4 GHz or 5 GHz, and which channel.
■ Walk around and find it by sound
Press "Start" and it beeps higher and faster the stronger the signal is. You do not need to look at the screen: just walk toward the higher beeps. You can use vibration instead. While you are searching, no full-screen ad gets in the way.
■ Compare your rooms
Wait a few seconds in a room and save it. The average of the last 5 seconds is kept. Line up the living room, bedroom, kitchen and more, and see which room is best and which is weakest. Useful for deciding where to put your router or a WiFi extender.
■ Nearby WiFi and crowded channels
Nearby networks are listed from strongest to weakest, and the one you are connected to is marked. Bars show how crowded 2.4 GHz channels 1 to 13 are, and it tells you in words which of channels 1, 6 and 11 is the least crowded.
■ 2.4 GHz and 5 GHz, explained simply
2.4 GHz reaches farther and goes through walls better. 5 GHz is faster and less crowded. Together with which one you are on now, it explains which suits which kind of place.
Good for
・Rooms where video freezes or calls break up
・Deciding where to put your router or extender
・Choosing where to put your desk or bed in a new room
・Places with lots of WiFi around that feel slow
How to use it
1. Open the app to see your current signal
2. Press "Start" and walk slowly toward the higher beeps
3. In a good spot or a room you want to check, press "Save this spot" to compare
What to know
Your phone re-reads the signal every few seconds, so move slowly. Android requires location access ("Precise") to show the WiFi name and the list of nearby networks. The app does not use your location itself and sends nothing anywhere. The signal strength alone works without the permission. There is no speed test and no list of connected devices. The app only reads the signal: it does not change your router or your WiFi settings.
