SMS Interface

Your Phone

Google Voice

Gmailnotification

of SMS

aaronparecki.com

You send me an SMS

Google Voice sends me an

email with the SMS

A Gmail filter catches it and

forwards it to my web server

then sends an email reply to the “from” address of

the SMS notification

Google Voice sends you an SMS

from my phone number

My web server retrieves my location data

* it would also be simpler to use Twilio for this, but I like that the SMSs are to and from my own number, hence the Google Voice round trip

Withings API reports to

IFTTT

IFTTT sends me an email with all the

data

A Gmail filter catches it and forwards it to my

web server and creates a new post

* the Withings API was too difficult to use directly, so I had to go through IFTTT as a proxy. I would love to find a simple Ruby/Sinatra or PHP app that someone else has written as a template!

Sleep Cycle App

Original Fitbit

Tracks steps, activity, and sleep

To track sleep, requires you wear it around your wrist

I was not able to sustain this because of the extra effort of using the wrist strap

Long button press to put into “Sleep” mode, gives visual feedback but no vibration (timer starts running)

@aaronpk

Jawbone UP

Always on my wrist, so I never forget about it

Battery lasts 8-10 days

Long button press to put into “Sleep” mode, gives visual and tactile feedback

I set up systems to passively collect data so that I have lots to work

with later!
