osmino WiFi is a WiFi network manager for Android that, among other things, helps you find all the free WiFi networks around you. Bus stations, grocery stores, restaurants, hotels ... if there's a WiFi network available, the app lets you know.
Although finding WiFi networks is really useful, it's not the only feature included in osmino WiFi. It also lets you test the speed of the network you're using at the moment, both for the download and upload speed. This is especially useful if you want to make sure you're getting the speed you're paying for.
Another interesting feature is the statistics record, which saves all the information about the different WiFi networks you've accessed. The virtual reality option is also an interesting one; it lets you look for WiFi networks by pointing your Android's camera in different directions.
Overall, osmino WiFi is a really useful app that helps you find WiFi networks, wherever you are. The rest of the features just make it even more interesting and well-equipped.
