I was one who was rather peeved about the failed app. Especially as I live in a high risk bushfire area.
The app did used to be pretty reasonable. Although I thought the GUI design was actually rather B grade (the icons used to denote the events made very poor use of space and were difficult to distinguish.) I was rather surprised to discover that the whole system is little more than a data scraper and a server that pushes the scraped data out to the app. The alert data is scraped from various government sources and aggregated. That is it.
The web site for the company gives you the sinking feeling that it is a tiny one or two person startup. They probably pitched the app to SA and Victorian state governments and asked $250,000 a year for it. If they had made it stick they would have been on to a good little earner. No doubt hoping to get the other states in as well in time, getting to the point where they might be pulling in say $3 mill a year. And really, not for much. But, as noted above, the update to the app last year made it perform worse - they lost my user settings when they did it, and it seems they simply never had the server resources set up or the required resiliency in the system to justify the price they asked. Altogether a bit sad, but also a very common story.
