I have used OmniFocus in the past and it’s a great app for Mac and iOS. I used it a lot while I was working but now that I’m more of a stay-at-home dad than freelancer, I haven’t used it.
I have been using Apple’s Reminders app which has served me well so far. It is obviously on all of Apple’s devices, syncs, and here’s the big one with me, it can share with other iCloud users.
Since having kids, my wife and I have needed to share more stuff together like grocery lists, bills, and other random things that we need to keep track of. We have a shared calendar, reminder lists of groceries and bills.
Before Yosemite and iOS 8, I had to create my own shared family calendar and reminders list. It was working out great except that on iOS 7, the Reminders app could not do custom repeat items. One of our utility bills is due every 3 months so I had to track that on my own or use OmniFocus.
Now, with Yosemite, iOS 8, and Family Sharing, Apple has remedied the little things that I couldn’t do or did already. I can create custom repeat items in Reminders, we have our own family calendar, reminders, and photo album.
OmniFocus is a great program and who knows, I might use it in the future again once I get projects again but for now, Reminders is my GTD app.
