Hi Nasir,
I am interested to use by myself and encourage others to use the Wikimedia Commons Android App [1]. But the problem is, i could not find the app by searching at Google Play and it is not listed even under the apps developed by Wikimedia Foundation[2].
See https://commons.wikimedia.org/wiki/Commons:Mobile_app :
[The Wikimedia Commons mobile app] was available for Android and iOS but
has not been maintained in a while and will likely not see further development, thus it has been removed from Play Store and App Store per this e-mail thread [1]
