Any experiences using HiveSmartHQ?

[Mark.G]

I'm using a spreadsheet at the moment to track inspections (multiple hives at several locations) and want to start tracking some extraction info too. I'd looked at apps a few months ago but hadn't found any that suited or even included extractions but I've been seeing this one mentioned on a couple of fb posts recently and found the fb page & website for it.  It looks like it could be more helpful but thought I'd check experiences others have had using it before I leap...
