To use this app I have provided a google drive link below. Just click on it and download the apk on your phone and you are ready to go!!! some credentials:
for employee & security login:
username : [email protected]
password : 123
for employee email in visitor you can use this email : [email protected].
while registering in visitor you need to write employee email as [email protected] as you can login as an employee only on this email
P.S ONLY The first response takes around 50 seconds loading time as the server is deployed in render and with less activity it spins down :))
