The app works very well, especially the GPRS module with the cloud sim card.
The subscription is only £46 per year which a no brainer as there are no call changes and the like.
The GSM sim module will not work on the app panels as it needed to be the GPRS module I believe but would have to check.
"Why I think its better or one of the best" Having used all but two of the manufactures apps (& equipment) out there I'm an easy man to please in that if its basic and works without spending hours setting up its got my vote.
I dont want to install equipment at a customers and then be on call 24/7 because the app's not working.
The "current" Pyronix equipment and customers app is basic set/unset and activate some outputs, that's it and that's all you need from an alarm app in my opinion.
