It’s a fine time to ditch paper for good and move to an all e-mail- and SMS-based system. Start with Google’s online calendar (google.com/calendar), which lets you set up multiple alerts for one event—for example, a text message one week before Mother’s Day, then another the day before in case you still managed to put off sending flowers. New event pop up while you’re away from a computer? Add it to GCal from your cellphone by texting the event details to GVENT (48368).
If you’re not interested in calendar functions, the Web site Sandy (iwant sandy.com) is a free virtual personal assistant whose sole purpose is to help you remember things. Just send it an e-mail such as “Remind me to move my car in 45 minutes,” and Sandy will e-mail or text you. It’s especially useful for recurring events like bills and birthdays. Add tags like “@weekly,” “@quarterly” or “@yearly” to your e-mail, and it will ping you every time the event comes up.
[Editors' note: Sandy went out of business this month. There's a project to create an open-source version of the service -- keep an eye on its progress here.]
Or skip the typing altogether with the voice-to-text
service Jott. Call 866-JOTT-123, say “reminder,” and answer the subsequent prompts (What day? Tomorrow. What time? 8 a.m.). Once your reminder is set, you’ll receive text and e-mail reminders.
