Habitica Planner

Read on for some ideas for using HabitRPG as a comprehensive planner.

Caveat
As others have pointed out, the single application that does everything every user needs for agenda and project management doesn't exist yet—and arguably may never exist. This is not an attempt to show how HabitRPG can replace the kitchen sink.

If your needs are simple, or you think-outside the box, you may find HabitRPG can meet most or all of your planner needs. Here are a few starter workarounds:

HabitRPG Direct Implementation
Here are some example implementations/workarounds for various elements of a planner.

Scheduled Actions: eg. appointments, meetings, calendar items

 * To-dos: Use the due date feature and/or add a date in the task title,
 * 4/01 7 AM dentist
 * 5/05 13:00 military report due
 * 5/04 dinner with friend
 * 5/15 5:30 dragon invasion
 * Habits: Add dated habits for regularly repeating habits:
 * 1st Pay Rent
 * 15th Pay Auto
 * Dailies: Add times dailies for repeating scheduled tasks
 * 8:00 am BREAKFAST
 * 9:00 - 10:00 School/Work

Unsched​uled Actions: tasks, habits, daily repeats with no assigned times

 * Method 1: list below and/or above scheduled actions by priority
 * Eat Healthy
 * 1st Pay Rent
 * 15th Pay Auto
 * Take Stairs
 * Method 2: list in between scheduled actions at approximate time you hope to do them
 * Brush Teeth
 * 8:00 am BREAKFAST
 * Clean Kitchen
 * 9:00 - 10:00 School/Work

​Projects: Multi-Step tasks

 * Add a unit of time, a step, milestone, and/or next action for each project to HabitRPG. In this case the substeps would be tracked elsewhere. This works well for moving forward projects that are difficult to break down into steps (eg. writing and revising a book) or contain multiple repeated actions.
 * daily: work on Project X 1 hour
 * habit: work on Project Y 2 hours
 * habit: next step in Project Z
 * habit: one document for Prepare Documents for Client Q
 * todo: Take Car to Garage (next action) for project Road Trip to Alaska
 * see more ideas in GTD HabitRPG
 * Upcoming Feature: Checklists

Additional Resources

 * request a feature: if it's a popular request and fits into the HabitRPG system, there's a high chance of implementation, but you'll have to wait (or submit code).
 * HabitRPG integration: HabitRPG has begun implementing integration with other apps and sites. So, there's an increasing chance of finding the feature you need in another app.
 * Google Calendar Integration/Sync
 * Google Tasks Integration
