Wifi Switcher will switch to the Wi-Fi network with the strongest signal from your remembered networks.
It runs constantly in the background. When the Android system scans the Wi-Fi networks, Wifi Switcher will check to see if any of your preferred networks has a better signal strength than the one you're currently connected to. If it finds one significantly better then it will switch to it.
At home I have a Wi-Fi access point downstairs and another one upstairs. If I go upstairs I stay connected to the one downstairs but the signal is much weaker. This app will automatically switch you to the stronger Wi-Fi connection.
Make it less sensitive to smaller differences in signal levels.
Fix crash when network ID is empty.
Choose network with highest priority when more than one of the same best strength.
Add Crashlytics crash reporting.
Made a User Interface.
Initial version. Functional but no nice User Interface.
