The web is now full of helpful reminder systems. I like Task.fm because you can write the way you speak and it converts your note into a smart reminder, such as if you tell it to remind you about “my meeting with Scott Thursday at noon.” You can set reminders to come to you via text, email, twitter or a phone call.
The basic level is free, and the deluxe is less than $4 a month.
Want another reminder system? Try my old favorite, Jott.
