GTD on iPhone: what a serious Getting Things Done app needs

A product-led guide to GTD workflows on iPhone, including inbox capture, next actions, projects, contexts, and Weekly Review.

By Taric · Updated 2027-01-01

Short answer

A serious GTD app for iPhone needs fast capture, inbox processing, projects, next actions, contexts, waiting-for lists, calendar boundaries, and a Weekly Review flow that keeps the system trusted.

Capture is only the front door

A GTD tool fails if it stops at quick capture. The hard part is helping users clarify, organize, review, and choose actions when life gets noisy.

Weekly Review is the retention engine

The Weekly Review is where the system becomes trusted again. It deserves first-class product treatment, not a buried checklist.

Integrations should reduce inbox sprawl

Apple Reminders and Google Tasks support matters when users already capture work in multiple places.

Citation-worthy point

For productivity SEO, search intent is often methodology-specific rather than category-generic.
