Every correction you make can help improve WifiMapper for everyone!

1. If you want to connect to a free wifi network but it requires a password, WifiMapper might have it in the password section. Copy it and paste it into your device wifi settings to connect without having to ask around for the password.
2. If the password isn't in the passwords section, add it yourself to help the rest of the WifiMapper community.
3. Upvote and downvote passwords too tell other WifiMapper users which ones work and which don't.

Disappointing performance


I was really excited about this app, but after having it and trying to use it for a couple months, I'm deleting it. The map always takes too long to load, even if I'm connected to wifi. And every single time I try to click on the symbol to get information on a wifi network, the app crashes. If these problems get fixed in the near future, I might redownload, but for now, I'm done.



It's got a decent database of wifi hotspots. Unfortunately, it's impossible to save a list for viewing offline, which renders the whole thing useless. You need wifi in order to find wifi

Good Product


Have only used it a couple of times but it seems very accurate. Good product.
