Code does not work as advertised, poor quality and poorly written. Hard to install, the "documentation" it has is a copy-paste from another site, which partially corresponds to this code. Had to do a lot of investigation on my own to get it partially working.
After struggling with the admin panel installation, I tried to get some help to make it work correctly as I was not receiving any notifications on my test device, but the only solution that came up was to pay for a $100 USD customization to make it work as intended; paid for this customization and got another poorly written code full of errors, which neither I nor the authors could make it work. They said that they would work on a solution and would let me know as soon as they got it, but it has been half year without a reply, and when I try to contact them I receive harsh replies or no reply at all.
I got in touch with another coder and he told me that the code was a mess, and recommended to begin from scratch.
My recommendation is to avoid this author.
Not able to setup the iOS version unlike adnroid app which was quite well documented and even support during android phase was much better.
If you ask for assistance they tell you straight for installation fee rather than taking it positively for updating their documentation. Very shallow doc for iOS app not acceptable...
The author himself couldn't get this script installed on my server when I asked for paid service. He said that my server has some ports blocked. However, I followed an online tutorial and was able to send notification from my server. This script isn't well documented and it was just waste of money and TIME!
