I just got an Iphone 4 and I was wondering what kind apps do you guys use for weight loss if any?

LoseIt to track calories, did a C25K program for running, and now use Nike+ for running.

LoseIt, c25k (not free, though, and with the gps feature), and iMapMyWalk.

As they said Lose it is a great free app where you can keep track of what you eat everyday, and set up some basics that you want to stick with.
C25K- $5 (its for someone who wants to start running couch to 5k.
Weight Watchers- free
Jillian Michaels Fitness Motivation- free.
Dining out Guide by Jenny Craig- free.
Weightbot- keep track of your weight easily- 99cents.
Calorie Tracker from LiveStrong.com- free.
Restaurant Nutrition- free.

Here is a link to the top 10 free weight loss apps:

I have a Blackberry and I use My Fitness Pal to track calories. There is an app for it on the iPhone as well.

I have used a couple and my favorite (and my good friend's new favorite) is MyNetDiary. The basic is free and it does everything you need. I also have an Ipad, so I had to buy that app, but I love it. One thing I find it is better about is the selection of foods. I hardly have to input ANYTHING. From my atkin's nutrition bars to a Croatian meat dish - it's already there.

I use it for my fitness, has a place to mark notes (so when I ovulate/TTOM _ I can mark it so I understand better the spikes in weight gains and so on). I've been using it for 5 months.

I use a Droid and MyFitnessPal and CalorieCounter are my two favorites

Thats the one I use too.Super easy to use on the go!

Awesome guys thanks! I checked out the Jillian Motivation one and I'll more than likely use that as well as Calorie Count!

I use Myfitnesspal to count calories and one of the Couch to 5k apps to do that. This isn't health related, but you HAVE to get plants vs. zombies if you like playing games on your phone. Ridiculously fun and addicting. Just thought I'd throw that in there lol

MedChick87 I have spent many countless would be boring moments entertaining myself with plants v zombies LOL

Anyway the apps I use are LoseIt! TargetWeight, and if you want to keep track of your monthly cycle I recommend IPeriod too(there is a lite version that's free or the full version for 1.99 I think the only difference I noticed is that you can change themes)

I recommend you "Eatwit". It is a kind of food journal and free. You can record what you've eaten simply, and if you want you can share it with your friends on Twitter of Facebook. It's fun!

You know I saw that game and because it had zombies in it I was going to get it but decided not to haha...I got zombie smashers which is super fun except I can't beat a certain level. lol I think I'll check it out!

Gosh!! What did we do before smart phones?! Definitely helps tracking easier and more convenient... easier to hold yourself accountable! Love it!
