Subscription based alternative to Rosetta Stone.

So far Duolingo is the winner for me in the free language app space. I love that it's gamified, social, community-support oriented. Caveat: One does come across some funny phrases sometimes, such as "I like eating pepper" but perhaps that adds to the fun... From their website, here's an explanation on how it can be free which I love for the savvy synergy:
"Here’s how it works: Somebody who needs a webpage translated uploads it to Duolingo. That document then gets presented to Duolingo students who can translate it in order to practice the language they are learning. When the document is fully translated, Duolingo returns it to the original content owner who, depending on the type of document they uploaded, pays for the translation."
An opportunity for lifelong learners everywhere to build skills and advance their careers by capturing and curating informal learning.

So many more and changing all the time.
Effectiveness and Time Management
I like this app a lot. Freemium model. Because I have the Pro version ($24.99 per year) it integrates with Google Calendar and Evernote and allows me to capture To Do items I remember while driving by voice recognition with "eye's-free" one touch.
Allows user to send emails schedule for a future date and time. Free.
This is a virtual assistant service that I'm so far enjoying. It's good for tasks which can be delegated easily with a fast email but will save you time. (eg. place order for catered food, arrange meetings, research etc). Various levels of monthly fee. (Full disclosure: if you use my link above, you get 50% off the first month and I believe I get a $5 credit.)
I've been a fan (and sometimes user) of 10 Daily Habits since I started my Coach training at CoachU in 2000. I've used paper and more often spreadsheets but I just got turned onto this simple, effective and share-oriented app and am finding it a nice addition to the process.
Other Self-Tracking and Quantified Self
Web or computer app which allows for the tracking of food and evaluation by composition. I'm currently using it to help me achieve a 6:3:1 fat:protein:carb food ratio. I'm testing the hypothesis that a higher fat diet will result in weight loss. My focus is on increasing fat which I believe will naturally lead to ease of reducing carb intake.
The app goes part and parcel with the hardware but this is one of the best ones due to the ease of tracking. I love it! I've previously been a hater of scales but this one softens the emotional impact. I did a QS talk on how the Withings scale and app worked for me as a result.
Another hardware/app combo deal. I only use this to track steps. I aim for 10,000 per day with a bare minimum of 4K per day.
More hardware! This one is the best I know for learning about sleep. It has amazing accuracy and seems to be able to tell through EGG when you're awake. Postscript: R.I.P. Zeo it was nice knowing you!
Love this app for the times when I'm running or walking outdoors. It let's me use a GPS to see where I've been. It's also a nice place to track indoor activites (like my treadmill walking) and other activities.
