I finally published the first update to WiFi Probe on the Android market. For this release, I have added some nice features: Probed networks are stored and their status is recovered once these networks are found again (given they provided Internet access or at least a captive page).
Additionally, I have added a settings menu with some cool settings. First of all, WiFi Probe can now run in the background (not as a service, but if the app is left using the home key or the device goes into standby) and continue scanning. It can notify you when an already probed free network was found again. Another new feature is the auto probe mode. In this mode, WiFi Probe checks each new network that it finds automatically. If the network is free, it will, depending on the setting, also notify you. So you can just start the app, put the phone in your pocket and be sure not to miss a free network on your way.
The first week WiFi Probe is available was quite encouraging, nearly a thousand downloads and about half of the downloaders kept using my app. So look forward to the next release!
