i dont think there is any android app for this but Setup Wi-Fi connection without connecting any display to raspberry pi, just simply create a text file and call it wpa_supplicant.conf and place into the /boot/ folder and add following contents to this file.
network={
ssid="MyWifi"
psk="mywifipassword"
key_mgmt=WPA-PSK
}
