It’s nice to use. That’s the main reason for me. It’s a specific app for each device (phone, tablet and laptop). Which means the UX is specifically tailored to the patterns of the device. The closest to it for me is Bear (my note taking app). IA Writer and Reeder came close (still not as nice)

What I most used is their deadline feature. On other to-do apps this is the due date, but for me that concept is a little confusing, since I use Things for both work, family and personal.

I have a recurring project called Monthly Bills and each tasks has a deadline of their payment.
