It’s been a while since I really used reminders, but I believe it doesn’t make those callback links I can get for Things tasks and Bear notes. I link back and forth between them all the time, so that’s something I would miss.
Overall Things feels like it’s set up precisely for my gtd-ish workflow, whereas reminders felt like I had to work for it to function like that. I can’t put my finger exactly on what it is.

Great! They don’t show up for me on kbin yet, but I’ll check back in a few days. Great apps.
