I'm a huge fan of https://momentum.earth. It's the best GTD system I've seen online, and the infinite sub-tasking/grouping, where each grouping can be set to be done either sequentially or in parallel, either surfacing the next task or all the tasks in the "Next" list automatically is amazing. Throw in the review settings, and the big picture areas of responsibility? And end-to-end encryption? It's amazing. - Source: Hacker News / about 2 years ago

The NirvanaHQ productivity app -- one of the better GTD-style todo apps -- is not Siri-enabled nor has a Share With... function. (The former is a killer, I mean, how many times do you want to jot down a note while driving?!). Source: almost 2 years ago
