OmniFocus
GTD at full depth for people with serious task loads
About OmniFocus
OmniFocus is what you graduate to when Things 3 starts feeling too simple. Defer dates, sequential projects, custom perspectives, deep review workflows — this is GTD implemented with total seriousness.
The learning curve is real, and casual users should stay away. But for people juggling hundreds of commitments across work and life, nothing else on Apple platforms goes this deep.
Licenses run $74.99 Standard or $149.99 Pro one-time, or $99.99 a year as a subscription that includes the web version.
