ALL LISTS (projects, next actions)
I have tried many things for calendaring and next actions on the iPhone. The best so far for me, seems to be the native Nozbe iPhone application for managing my next action and project lists. They do a fantastic job!
ALL TIME/DATE SENSITIVE with SMS and Gmail reminding.
Nozbe unfortunately, and despite doing the next action / list management thing exceptionally well, has not added sms or email reminders to their calendar so I use SaiSuke iPhone app to sync with the Google Calendar instead of Nozbe for all calendar related items. Google's calendar is better than I thought it would be initially. I can quickly (at lightning speed) add a calendar item via a Gmail message. You would have to see it in action to understand what I am talking about. For now at least, calendaring with Google is the best way to go for me.
Now I need a tickler. This is the 'missing piece' to my puzzle. I have looked at Nozbe for this and just can't quite get this to work the way David suggested in his attached write-up on it. I would prefer mobility with this one, but to be honest (iPhone or no iPhone), I simply can't find 'anything' really that will do this tickler file thing electronically.
