Exactly, each version is an upgrade. Like version 1.00 then 1.01 then 1.02 That counts as 3 different appz, get it. I've been observing this with the weather appz, etc. There are not 280 "unique" appz, even though the number shows 280 as of today. It went from 279 to 280 today with the "latest" ncalc. Which if you look is called Ncalc upgrade. Think how many OMWeather theme upgrades and versions there have been!
