Here are some of my favorite self-help Android apps. These are the ones I actually use regularly.

Content Intake / Note-taking

Audio Speed Changer - (link) - Lets me listen to audio programs faster or slower. - Great audio program that allows you to speed up or slow down your audio tracks from 25% - %400 (like VLC). Easily loads tracks by folder w/o a playlist, you can set start and end markers, etc.

Aldiko Book Reader - (link) - My ebook reader of choice.

CamScanner -Phone PDF Creator - (link) - Awesome app that allows me to take photos of articles or things I see while I'm out and creates a PDF right then and there of the snapshots.

Diaro - diary writing - (link) - My preferred journaling app.

Easy Voice Recorder Pro - (link) - Best voice recorder I've found that's quick to launch and use. Voice memos, recording meetings, etc.

Health and Fitness

A HIIT Interval Timer - (link) - The best programmable workout timer I've found. I love this app. It also vibrates your phone so if you're listening to loud music, you feel it.

Instant Heart Rate - (link) - Uses your camera and LED flash to get your pulse. Works great!

100 Push-ups - (link) - Straight forward pushup workout program to get to 100 consecutive pushups.

CC Tracker - (link) - An app made for logging your Convict Conditioning workouts.

Sensor music player - (link) - I love this music player when I'm working out. It uses your phones sensors to skip the track and pause the player (via shake, waving your hand over the phone, etc.)

Nutrition

Fooducate - Healthy Food Diet - (link) - Scan the barcode on any food item and get nutrition notes on what you're eating and drinking. Love it.

Dirty Dozen - (link) - Quick access to the fruits/veggies with the most pesticides and the least pesticides.

Productivity

Astrid Task/To-do List - (link) - My preferred "To Do" list. Syncs with my calendar, great reminders.

StayOnTask - (link) - This app allows you to set a time interval where it checks on you to see if you're staying on task.

Business Calendar - (link) - Just the best calendar around for a variety of reasons. It's been worth every penny to me.

Gentle Alarm - (link) - I love the pre-alarm (doesn't wake you up if you're in deep sleep). The regular alarm slowly gets louder and louder. You can set a safety alarm that's super loud. You can make it say stuff to you. All sorts of great stuff.

Fashion

How to Tie a Tie - (link) - How to tie like every tie knot there is.

Sex

Sex Positions- (link) - Great app with user submitted votes. Add variety, have fun, have a great conversation.

Sex Positions #2- (link) - Same as above but more.

Spirituality

Buddhist Meditation Trainer - (link) - Gives you an idea to meditate on for a few minutes a day.

AMAZING ZEN QUOTES- (link) - Great grounding quotations.

Zen Koans - (link) - Zen Koans.

Miscellaneous

Guard My Angel - (link) - This app is amazing and I just had to include it. For those of you with people you care about and worry about it (girlfriends, etc), it's a way to make sure they get home safe and if they don't it sends alerts to people without intervention. (Not really self-help, but I thought more people should know about it!)
