David Allen's Getting Things Done revolutionized productivity by solving a fundamental problem: your brain is terrible at remembering tasks but excellent at pattern recognition and creative thinking. GTD works by creating an external system that captures everything, so your mind stays clear for the work that actually matters.
On iPhone, this means finding an app that makes capture effortless and review automatic. Most people fail at GTD not because the method is wrong, but because their tools make it harder than it needs to be.
The Five GTD Stages: What Your iPhone App Must Handle
GTD breaks productivity into five stages: Capture, Clarify, Organize, Reflect, and Engage. Each stage has specific requirements that determine whether an app will work for serious GTD implementation.
Capture means getting every thought, task, or idea into your system within seconds. On iPhone, this requires an app that opens instantly and saves immediately โ no waiting for sync or complex input screens. The two-minute rule applies here: if capturing a task takes longer than doing it, the system fails.
Clarify is where you decide what each item actually means. Is it actionable? What's the next physical step? Your app needs to support this processing workflow, not just store random text. This is where most note-taking apps break down โ they capture well but don't help you think through what comes next.
Organize means sorting items into the right buckets: next actions, waiting for, someday/maybe, reference material. Your iPhone app needs clear ways to categorize and tag items so nothing gets lost in a giant unsorted list.

Context Lists: Why Location and Tools Matter
GTD's genius lies in context-based organization. Instead of prioritizing by urgency (which changes constantly), you group tasks by the context needed to complete them: @calls, @computer, @errands, @home. This matches how you actually work โ when you're at your computer, you want to see only computer tasks.
On iPhone, this means your GTD app needs robust tagging and filtering. You should be able to pull up your @calls list when you have ten minutes between meetings, or see @errands when you're near the store. The app should make it easy to add context tags during capture, not force you to remember them later during review.
Many productivity apps ignore this principle and focus on due dates instead. But GTD recognizes that most knowledge work doesn't have hard deadlines โ it has contexts where the work becomes possible. Your iPhone app needs to support this way of thinking, not fight against it.
The best GTD implementations also support energy levels. Some tasks require deep focus (@high-energy), others you can knock out while half-asleep (@low-energy). Your phone knows when you're moving, sitting, or have been idle โ smart GTD apps can surface the right tasks for your current state.

Weekly Review: The Make-or-Break GTD Habit
Weekly Review is where GTD lives or dies. This is when you process everything you captured, update your lists, and plan the next week. Without consistent weekly review, GTD becomes just another task list that grows until you abandon it.
Your iPhone GTD app needs to make weekly review pleasant, not painful. This means fast search across all your notes and tasks, easy ways to bulk-edit and reorganize items, and clear views of what's been sitting untouched. Many apps make review tedious by requiring too many taps to see and update items.
The review should also surface patterns. Are you consistently not doing certain types of tasks? Are some contexts never getting attention? A good GTD app helps you see these trends so you can adjust your system, not just accumulate more stuff.
Mobile review has unique advantages: you can do it anywhere, during small pockets of time. But it also has constraints โ small screen, touch interface, possible distractions. Your GTD app needs to be designed for these realities, not just ported from desktop software.

TaskLoco: GTD Principles in Practice
TaskLoco applies GTD principles without the complexity that kills most implementations. Capture happens through instant note creation โ no categories to choose, no required fields, just type and save. The app assumes you'll clarify and organize later, during proper review time.
The sticky note interface mirrors how GTD actually works in practice. Each note holds one thought, task, or idea. You can cluster related notes together visually, just like arranging physical sticky notes on a wall. This makes weekly review feel natural โ you're literally looking at your thoughts spread out in front of you.
Context happens through simple tagging and search. No complex project hierarchies or forced categorization. If you want to see all @calls tasks, search for @calls. The system stays flexible as your contexts change, which they will.
TaskLoco Premium adds reminders and file attachments, turning notes into complete task packages. Attach the document you need to review, set a reminder for when you'll have time, and the system delivers everything together when the moment arrives.

Frequently Asked Questions
What makes a good GTD app for iPhone?
A good GTD iPhone app needs instant capture (open fast, save immediately), flexible organization (tags and contexts, not rigid categories), and effortless review (see everything at a glance, update quickly). The app should support GTD principles, not fight against them.
Can you do GTD completely on iPhone?
Yes, but you need an app designed for mobile GTD workflows. The key is choosing tools that make capture effortless and review pleasant. Many people successfully run their entire GTD system from their phone using the right app and consistent weekly review habits.
Why do most GTD apps fail?
Most GTD apps fail because they're too complex or too simple. Complex apps require too many decisions during capture, killing the flow. Simple apps don't support the organization and review workflows that make GTD actually work. The sweet spot is effortless capture with powerful review.
How do you handle contexts in a mobile GTD app?
Use simple tagging: @calls, @computer, @errands, @home. Tag items during capture or clarify, then filter by context when you're ready to work. The best mobile GTD apps let you see only relevant tasks for your current situation and available tools.
What's the biggest GTD mistake on mobile?
The biggest mistake is choosing an app that makes weekly review painful. If you can't easily see and update everything you captured during the week, the system breaks down. Review should feel like planning your next moves, not cleaning up a mess.
How often should you do GTD weekly review?
Weekly review should happen every week, same day and time. It typically takes 30-60 minutes to process everything you captured, update your lists, and plan ahead. Skipping weeks breaks the system because you lose trust that everything important is captured and organized.
Can TaskLoco work as a GTD app?
Yes, TaskLoco follows core GTD principles: instant capture through quick notes, flexible organization with tags and search, and visual review that lets you see everything at once. $9.99/month per person (currently $4.99/month per person for first 500 charter members with code CHARTER50)
