While using 2Do, I learned to use the calendar app or the Due app on my iPhone to remind myself to do the reviews. If a function didn’t exist in the app itself, I find another app that can co-exist. Ideal? No really. But as long as I can find something to plug the hole, I’m OK.
Any projects or checklists that have a lot of change in them (adding, deleting tasks, constant environmental changes) will get a shorter review process because I need to review a project or list on a more continuing basis.
Someday/Maybe projects will get a monthly visit to be reviewed. You might feel more comfortable with doing it once a week or every 2 weeks. I use a monthly checkup because most of these projects don’t require action yet. But I can visit them once a month to see if I need to start something up in the next month.
Most of my active projects will be reviewed weekly.
I think Mat Rhein mentioned using the start date as a way to review. Then defer it again to another future date for a future review.
