How good is the wifi right where you’re standing? WIIFII tells you with one number, one word and one colour, then helps you find the weak spots and fix them.
Coming soon to Google Play
The whole screen turns blue, green, yellow or red as the signal moves, and the point where video calls get shaky is marked on the ring.
Band, channel, link speed, Wi-Fi generation, and how fast your router is answering, all at a glance.
Stand somewhere, name it, save. WIIFII times your router too, then ranks every spot from strongest to weakest.
Export it all as a spreadsheet to plan where a mesh point or extender should go.
Every network in range, grouped by name, with its security, Wi-Fi generation and access point maker. Open networks and old, breakable security are clearly marked.
Tap any network for the details, including whether your own connection actually reaches the internet.
See how crowded each channel is on 2.4 and 5 GHz, which one you’re on, and whether switching would help.
A log of every time your phone switches band, channel or access point as you move around, with the signal before and after.
And a home-screen widget, for a glance without opening the app.
WIIFII reads your wifi on the phone and keeps everything there. It never sends your data anywhere: not to us, not to anyone.
Yes. Every feature is free, with no ads.
Android only lets apps see wifi network names and the list of nearby networks if they have location permission. WIIFII uses it only for that and never records where you are. The signal reading works without it.
It’s the signal strength in dBm. Closer to zero is stronger: around −50 is excellent, −67 is where video calls start to struggle, and −80 is very weak.
No. WIIFII measures the wifi between your phone and your router, which is usually what changes from room to room. It also times how quickly your router answers, and tells you whether your connection is reaching the internet.
Not at the moment. Apple doesn’t let apps read wifi signal strength in the same way.
Android 7 and later. Some details, such as link speeds and your connection’s exact security type, need newer versions of Android.
