This simple yet oh so clever site, Oh Don’t Forget, is a chip off the old string around the finger technique- Don’t forget to get dog food, drop off your dry cleaning, call your mom on her birthday! Yet it’s done via the web and text messaging, which is super cool and way more effective.
All you do is enter your cell number, set a date and time for the text to come in, and then type out the reminder that you want to send yourself. While I’m sure I could do this by programming my phone calendar to beep or buzz when I needed to be reminded of something, that’s just so 2007…

Side note- I’ve also used this service as a “just in case” on a random “coffee” date. I set up a designated time to text myself a perfect excuse to leave. My phone goes off and if I’m having a bad time, I simply show him the text and– Sorry, I HAVE to get to the hospital- my cousin is having her baby! I’m so excited- thanks for the drink- call me sometime!— and if I’m not, simply close the phone and smile. Thank goodness it wasn’t needed, but you really never know!
