Sadly, there's not one app that interests me.
There are a few photo apps I'm sort of interested in, but my record of actually USING the apps in these bundles has been rather spotty, I'm afraid.
One app I do/did use and got in a bundle many moons ago (Sous Chef) now instantly quits in Sierra. I then tried to find an update, only to discover it had been discontinued in 2012!
Luckily, it synced the recipes I used between both Macs, so I can still get to them before I update the iMac. I'll have to move them elsewhere, I guess. It was a nice little app - it's too bad. I have a copy of MacGourmet from another bundle - an older version 3.x version (it's up to 4.x now) which still works. That I can upgrade for $25 USD. But on the whole, I have way too many little apps from bundles which I have to keep looking up because I can't remember what the heck they do and why I have them.
